Best free strategy games for iPhone

Hero Academy

Hero Academy is a turn-based, multiplayer-only tactical combat game that pits cartoony armies against one another. Each side gets five actions points every turn to move their troops, kit them out with gear, cast spells and otherwise attack opposing units on the board. Each player (online, either random or a designated buddy) has one or more crystals they must defend while trying to destroy the other side's. You can also win by running your opponent out of reinforcements, as each side only gets so many of each type every game.

Hero Academy includes The Council army (humans) for free, but charges for the others, such as Dwarves, Dark Elves and The Tribe (orcs). You can also pay for fancy army-themed avatars as well as taunts to make your soldiers jeer after a turn.

Spice Bandits

As you level up, you get upgrade points (which can also be bought with spice) to customize your play style as you see fit - cheaper turrets, faster rate of fire or more mesmerizing disco music are just a few options. Spice Bandits lets you buy spice through in-app purchases, which also eliminates ads between levels.

Triple Town

Triple Town is a simple puzzle game where you place various kinds of greenery on a small grid so that you can line up three of a kind and have them merge into another object. For example, three patches of grass make a shrub, three shrubs make a tree, three trees make a house, and so on. Occasionally, you'll have to put down bears, which block building on squares until you're able to corral them into a confined area. You keep building until you run out of squares to build on, which actually takes awhile since the board is continually shifting with sets merging together and opening up space.

Triple Town is monetized by providing only a limited number of placements. Your move count regenerates over time, but you can pay for more turns, or simply buy unlimited turns for $3.99. The coins you earn through gameplay can also be spent on buying particular items, like bots, which can eliminate pesky bears with a single tap.

Don't get too trigger-happy, since your ammunition is limited. If you're not into shooting down your buddies, you can also invite Game Center wingmen to play through the campaign levels co-operatively.

A lot of the hardware upgrades require you to use premium coins, which are sold in batches for $0.99 and up or earned through regular gameplay.

Frontline Commando

Frontline Commando is an on-rails third-person shooter about a gung-ho military man left behind enemy lines. You dodge behind cover with single taps, and pop out to take aim and eliminate nonspecific middle eastern insurgents. Don't get too attached to that wall you're hiding behind though, since it can be destroyed as a firefight drags on, and grenades can quickly flush you out into the open. When you level up, new weapons are unlocked for purchase, plus you get a few bars of gold, which can be used to buy premium items. Weapon upgrades span assault weapons, sniper rifles, shotguns, and grenade launchers, each with their own set of damage, clip size, reload speed, and accuracy attributes.

You can also increase survivability with medkit purchases and body armor upgrades. When things get too hot, you can buy airstrikes to clear out the immediate area. Both "war cash" and gold can be bought through in-app purchases.

Best free sports games for iPhone

Baseball Superstars 2012

Baseball Superstars 2012 is a whimsically exaggerated baseball game with Japanese-style characters and dialog. While the game keeps tabs on minute details, such as batting averages, running speed, stamina, and confidence levels, there are some more cartoony encounters with "super players", with ridiculous anime costumes and powers. As a batter, you can control where you swing by tilting the iPhone, but don't worry, you won't actually have to swing it like a bat - just tap the screen at the right moment. Pitching is done through a series of swipes within a box. You'll encounter plenty of challenges, including injuries which require recuperation in a hospital, managing your team roster, and playing against friends online. Personally, I found this game impossibly hard when set on normal difficulty, but I'm not a sports guy. Baseball fans will love it, though. For more baseball-themed apps, check out our ballgame roundup over here.

Through in-app purchases, you can get G points, which are spent on character items, training sessions to improve your stats, or even buy levels for your batter or pitcher.

NFL Pro 2012

NFL Pro 2012 is a full-fledged football game complete with leagues, playbooks, and extensive rosters based on real players and teams. Your players gain experience and level up as you go, letting you improve their stats in a number of areas, like run blocking, catching, awareness, and agility. Every down, you pick a play available (either offensive or defensive), and while you manually control one player, the AI handles the rest. Controls during play are dead simple, but most of your time will be spent flipping through and picking plays. Unfortunately, your selection is really limited to start, and it takes an obscene number of credits to permanently keep playbooks.

Every game you play uses up energy, which you can replenish or time or through in-app purchases. Experience points to level up your players can also be bought, along with credits to buy new playbooks, stadiums, gain access to new teams, divisions, and conferences, and extend quarter lengths.

Real Soccer 2012

Real Soccer 2012 offers a wide variety of gameplay types in a fast-paced, realstic package. The core controls are laid out with a standard virtual joystick and sprint, pass and shoot buttons, but progresses in complexity with fancy gesture-based maneuvers. You can unlock a variety of different cups, starting with International, and working your way to Asian, African, American, and European cups, plus there's regional league play unlocked as you play and level up. Just remember that you're limited by how many matches you can play by a stamina rating, which recovers over time. Loading screens have bits of trivia, and occasionally test your own football, err, soccer knowledge with a multiple choice quiz.

Playing Real Soccer 2012 earns you coins which can be used to purchase new soccer balls that provide a variety of different bonuses, like extra XP per match. "Cash" is Real Soccer 2012's premium currency, which can be traded in for international teams, additional stamina, team stat boosts, access a few select stadiums, and even the ability to clear all yellow cards.

Best free casual games for iPhone

Tiny Tower

Tiny Tower is a really simple social management game with 8-bit-style graphics. Your job is to populate a tower with bitizens, assign them jobs relevent to their skills, keep their respective businesses stocked, and build more floors on top of your building. Over time, your bitizens earn you money which can be spent on purchasing new stock for various types of stores, or for putting the next storey onto your tower. You'll need to ferry bitizens from the ground floor with the elevator if you'll ever want to move new people in, plus once in awhile VIPs will provide you extra bonuses, like knocking off a few hours from your restocking time.

Tiny Tower occasionally gives you Towerbucks for handling the elevator, which can be used to hurry restocking, construction, or elevator upgrades. Towerbucks can also be bought through in-app purchases.

Draw Something

As is, Draw Something provides only a limited palette of colors, but you can buy more through in-app purchases. You can also buy bombs, which are used to offer a fresh selection of words if you're drawing, or eliminate letters to chose from if you're guessing.

GodFinger All-Stars

GodFinger is a fun little world control game where you tend to a little planet full of villagers. By spinning around a cross-section view, you make sure they're happy and productive, and check in on them time to time to collect the gold they generate. That gold goes to upgrading their homes which can house more people, who then, in turn, produce more money. Of course, you have to tend to their needs, like providing rain and sun for the farms, as well as altars to worship you from. To accomplish all of this, you do these gesture-based miracles, but they burn up Awe points, which regenerate over time, or can be bought through the app store.

Over time, you complete missions, gain experience points, and expand the surface area of your planet. You can have a lot of fun around your world by raising and lowering the ground, decorating the planet with appropriate and flinging your hapless devotees beyond the horizon.

Cut the Rope Free

Cut the Rope is a popular game that involves dropping a piece of candy into a hungry green creature's mouth by slicing rope with swipe gestures. While the candy's dangling and swinging, you use nearby tools such as magic hats and air puffers to avoid obstacles, like candy-devouring spiders and destructive spikes. If you can get the candy to pass through any of the three stars on the level, you gain bonus points and bragging rights, but they're strictly optional.

Though you only get 18 levels in the free version, the full version with 250 levels is only $0.99.

Fruit Ninja Lite

Fruit Ninja is a well-known slice-and-dice game where you swipe through various kinds of fruit as they sail through the air. You get bonus points for chopping through four or more fruit at once, but you have to make sure to avoid the bombs that get tossed in every now and then. Different kinds of bonus fruit can really help out, such as the freeze banana, which slows the movement of everything the screen, making for easy targets.

In the free version, you get Classic mode in which you only get to let three fruit hit the ground, but the paid version, available for $0.99, includes a Zen mode where you cut up as much fruit as you can within a limited time frame, among other game modes.

Angry Birds Free

The free version of Angry Birds gives you a total of 24 levels, but you'll need to drop $0.99 in order to get tons more.

Jetpack Joyride

Jetpack Joyride is a side-scrolling evasion game with simple one-button controls and a great sense of style. You play as a rebellious bureaucrat named Barry who's tired of the work at his top-secret military lab, and decides to snag the company's experimental jetpack for a jaunt through the facilities. Holding your finger on the screen puts the gas on the jetpack, letting you elevate over obstacles such as laser security systems and incoming missiles. Along the way, you'll also be able to snag other experimental vehicles, including the Crazy Freaking Teleporter, and the Profit Bird which is powered by concentrated satire.

You earn coins based on how far you make it through, but can also pick up loose coins through the level. You even earn more through completing missions, like high-fiving the scrambling scientists on the ground floor. Those coins are spent on new jetpacks, outfits, and soon gadgets, all available through in-app purchases stored in The Stash. Of course, you can buy more coins through in-app purchases, too.

Temple Run

Temple Run is a dead-simple platform game where you sprint through ancient ruins while being chased by displeased spirits. You turn corners, duck under obstacles, and leap over pits with swipe gestures while collecting coins along the way. There's a bit of accelerometer control, so you can snag coins in the middle or to the left or right side of corridors by tilting the iPhone, but for the most part, you're just relying on twitch reflexes. Gameplay can be extremely bite-sized, but still amply rewarding.

The coins you collect while temple-running (or in-app purchasing) can earn you power-ups like speed boosts, new unlockable characters, and even exclusive wallpapers.

Cordy Sky

Cordy Sky is a jumping game where you're an adorable little robot trying to get from the ground of an alien planet to a docked spaceship so you can continue on your intergalactic mission. Small bouncy platforms aid your ascension, but be careful, otherwise you drop down to the bottom and have to start all over. Luckily, you have a fellow robot called Volt that can grab you if you drop too far, but only if you've collected the appropriate token while climbing skyward. Your trip is split up into five sections, the end of each being marked by a fuel cell you need to get the spaceship running again. Controls are are either through virtual buttons, tilt, or swiping.

As you go, you collect gears, which can buy one-time boosts, permanent power-ups, or vanity costumes. Of course, you can always just buy gears through in-app purchases, but you can get by perfectly well on your own. Despite the kiddy graphics, the game is actually pretty challenging at points.

Six-Guns

Six-Guns is an open-world multiplayer western. You embark on missions for beleaguered commonfolk, handling the likes of bandits and supernatural nasties to bring some iotum of peace to the wild west.

In addition to being able to buy in-game currency through in-app purchases, you can also get Sheriff Stars, which access high-end gear and auto-complete missions, though you can also earn them through watching ads. You're even able to buy experience points and health boosts, if you're having trouble getting through a particular quest.

The social element is very rich, with full support for guilds, and plenty of common spaces. Every mission you play is automatically instanced, so others people freely spawn in to help you out. Daily missions, implant crafting, and a ton of people to chat with insure you'll always have a reason to come back for more.

Platinum is the premium in-game currency, and is shared across accounts if you happen to play Pocket Legends as well. You can spend it on vanity items, like fancy jetpacks and robot pets, but you can also spend the the coins you earn through regular gameplay to keep your equipment in good repair and up-to-date.

Forever Drive

One of the core elements of Forever Drive is the track builder. It's pretty simple - you draw a line from one end of a square to the other, pepper some scenery along the sides, and the highlighted turns, varied elevation, stars, and extra traffic are added in automatically. You then have the option to share these tracks online, which then randomly compose the arcade mode of other players. When you play, you get fed a series of user-built tracks which you can rate up or down after you're done driving them.

There are also weekly leagues where you have a chance to win in-game currency, with which you can buy a few unlocks, but the vast majority of car bodies, variations, and paint jobs are earned by gaining experience points throughout gameplay. I was really happy with Forever Drive, and I'd go so far as to say it's one of the better games I found when hunting for the best free iPhone games out there. Definitely check it out.

Snuggle Truck

Snuggle Truck is a simple side-scrolling racing game where you're trying to drive a bunch of stuffed animals to the zoo in a pick-up truck without having them bounce out of the back along the way. It sounds like it's for kids, but the game was originally called Smuggle Truck, where the premise was to get Mexicans to America where a better life awaited them. Obviously Apple wasn't a fan, so the developer changed it up, though the core gameplay remained the same. You tap left or right to put your foot on the gas or back up, and tilt your iPhone to make sure your truck lands evenly when sailing through the air. Like Forever Drive, there's a treasure trove of user-generated courses, all ripe for the downloading and rating. You can build your own courses, complete with power-ups, obstacles, and waypoints where new fuzzy animals are tossed at you to catch in mid-transit.

Through in-app purchases, you can drive flashier pick-up trucks, but the vast majority of content is thankfully available for free.

GT Racing: Motor Academy Free+

Motor Academy Free is a more down-to-earth, mostly-realistic racing game. You earn coins by completing tours, special invitation events, and completing contracts. Starting off, there are a bunch of levels where you earn various licenses, which help you learn how to drive different classes of cars. Coins let you buy a variety of recognized brand-name cars, like Bugatti, BMW, Bentley, Jaguar, Ford, Chevrolet, and Audi. They even kindly give you the option to rent the car for a round if you don't have enough to buy it outright. Even this racing game has some RPG mechanics in it, including quests which you complete, and leveling up to unlock new cars and courses.

Coins are earned through regular gameplay, while in-game cash is mostly bought through in-app purchases, which you can trade in for new cars.

CloudOn, a free iPad app that offered Microsoft Office functionality with Dropbox support, appeared briefly in the App Store yesterday before going up in a puff of smoke a short time later.

CloudOn has responded saying their app has "sold out", but we think this may have had something to do with server overload.

Thanks for your support of CloudOn! We're currently sold out. We look forward to the feedback we will receive as we continue to support the many users that have registered in this first phase.

The fact that CloudOn came with full Dropbox support for storing and managing office files on-the-go was a great idea for power users, and the overall offering is unique in respect to beating Microsoft to the punch at their own game. This could be another reason the app is no longer available, as Microsoft could have called shenanigans if CloudOn didn't go through the appropriate channels before release.

I gave it a quick whirl when it was actually up and running, and noticed the app was somewhat sluggish from the get-go (probably due to how much it relies on the cloud backend to get things done paired with the influx of users hammering their servers).

We'll let you know as soon as CloudOn is back in the App Store. In the meantime, here's its description:

• Use Microsoft Word, Excel and PowerPoint on your iPad to create or edit documents.
• Rename, delete and manage documents with your Dropbox account
• Display, edit or create charts, change formatting, spell check, insert comments, into any Word, Excel or PowerPoint files
• Track changes while reviewing Word documents
• Use pivot tables and insert formulas in Excel workbooks
• Display and edit animation or transitions in PowerPoint presentations
• Present in full PowerPoint mode (not in PDF)
• Open files directly from your iPad email accounts or Dropbox account
• Automatically save documents to avoid losing changes

Manton has an interesting post up where he theorizes that a lot of the problems we've seen in the App Store, from the across the board 30% revenue cut Apple requires for paid apps, to in-app purchases, to iAds, and now subscriptions can all be traced back to Apple's decision to host free apps for free. In other words, that the cost of approving, hosting, marketing, and delivering free apps is high enough that Apple is struggling and stumbling to make enough off paid apps and content to cover it.

When Steve Jobs said it, offering free apps for so little seemed almost foolish, like Apple was compensating for the high 30% by giving too good a deal to free apps. Why not charge some hosting fee? Or why not give up exclusive distribution and let free apps be installed directly by the user without forcing everything through the App Store? Unlimited bandwidth, promotion in the store, and everything else just for the $99 dev program fee was a pretty good deal. And now I wonder if Apple hasn't been backpedaling ever since, trying to make up for that mistake.

So in order to run the App Store at just over break-even -- as Apple reports they during their financial results -- they need to earn enough off paid apps to defray the cost of free apps. They also have to make sure they don't lose revenue -- they can't let developers offer free apps, shouldered by Apple, with ads that make money for Google or that use subscriptions or other forms of outside payments as a way to circumvent the revenue sharing. (Which is why we said from the beginning Apple couldn't charge less than 30% for subscriptions or every paid and in-app purchasing app that could would just switch to subscriptions in order to keep more of the revenue.)

Are free apps a burden? Apple doesn't say so it's difficult to tell. It's possible the cost of approving, hosting, marketing, and delivering all those free apps while not insignificant is easily covered by paid app purchase. (I'm not counting profits from hardware sales because Apple is going to want App Store to be profitable, if only barely, on its own.) If it is, then Apple certainly didn't make a mistake and their platform has benefited tremendously from having free apps in the ecosystem. If free apps are costing Apple significant money and resources, however, and if that cost is increasing as they reach milestones like hundreds of thousands of apps and billions of downloads, then what does Apple do?

Manton's answer is for Apple to allow side-loading of apps -- to allow developers to sell and users to install apps from outside the App Store on iOS the same way they do now on the Mac. That would take the hosting burden away from Apple... but it would create a new burden on consumers.

Sure, it would be a good answer for some developers and power users but certainly not for all of them -- even most of them. Many developers value the trust relationship Apple has created for users. Successfully creating a place where users feel safe and secure enough to buy an app and know they won't get malware or be defrauded, and can delete it easily if they don't like it is invaluable (even if not always valued.) That simply didn't exist before the App Store (it certainly wasn't the case with Palm OS and the Treo, which was side-load heaven and mainstream user hell.)

And not to be too cliched about it but if my mother couldn't find an app on the App Store she would either simply not realize it existed or bug me to help her side load it. (Or she would call me asking if "Amazon Kandle" was safe to buy via "PayPul".) That's not an Apple solution, and it's a crummy mainstream experience overall.

So what is the answer? Getting rid of free apps and creating a baseline of $0.99, like iTunes music of old, doesn't seem realistic. The genie is out of the bottle. Given how Apple has added in-app purchases, reversed their policy and allowed in-app purchases in free apps, added iAds, added subscriptions, they certainly don't seem to have found it yet.

Apple has just sent out a letter to developers introducing in-app purchasing for free apps.

UPDATE: Developers Erica Sadun on TUAW, and Marco Arment delve deeper into the subject, as does Techcrunch (twice).

ORIGINAL: Here's what Apple had to say:

In App Purchase is being rapidly adopted by developers in their paid apps. Now you can use In App Purchase in your free apps to sell content, subscriptions, and digital services.

You can also simplify your development by creating a single version of your app that uses In App Purchase to unlock additional functionality, eliminating the need to create Lite versions of your app. Using In App Purchase in your app can also help combat some of the problems of software piracy by allowing you to verify In App Purchases.

Visit the App Store Resource Center for more details about how you can add In App Purchases to your free apps.

So in one email, Apple ends the clutter of Lite apps, provides a real possibility for demoware (a developer can provide 1 level of a game, for example, for free, and 10 more via in-app purchase), and offers developers the carrot of anti-piracy measures at the same time.

Previously, Apple was resolute about "free apps stay free" so as to avoid user confusion. What changed their mind, all of the above? And will in-app purchases in free apps be extra-carefully marked to avoid just such confusion?

One of the highest profile iPhone games to state, EA's Spore, retails on the iTunes App Store for $9.99. Now, however, you can also get a "free" version, Spore Origins Lite Edition (iTunes link). The catch? It's teaser consisting of 1 level. Since Apple doesn't (yet?) have a model for demoing apps ("try" instead of "buy"), it's likely the only thing developers can do to give potential buyers a real preview. They hope, after one or a short number of levels, you'll be hooked enough to pony up the bucks for the full blown version.

How's this working? Well, Spore Origins Lite is not in the iTunes App Store Top 10... Pac Man Lite, which uses the same model, sits at number 5 in the free listings as of this posting, but it's full blown counterpart in nowhere to be found among the top 100 paid Apps.

What does this tell us? That people would rather pay nothing for a Lite edition than something for a full game? Or is it simply that the whole App ranking mechanism still broken?

Have you downloaded any free "Lite" Apps? And if so, how many have convinced you to move on up to the full version?

Last month, Dieter let us know that Facebook's popular, but feature-thin App Store application would be getting an update to (hopefully!) bring it up to par with the older WebApp version accessible via MobileSafari browsing. The due date was September, and boy did they just manage to sneak it in under the wire! Check out the iTunes App Store for Facebook 2.0 (still free!).

So what's in the Facebook 2.0 update?

TUAW (nice redesign, guys!) notices that the iTunes App Store no longer has a link on the lefthand side to browse all free apps. The best we have now is the Top 100 Free Apps over on the right. TUAW is hopeful that Apple will bring back the link to browse all them free apps, and indeed, so are we. Even stores that traditionally only sold for-pay mobile apps like the Mobihand store sister-site WMExperts have seen the writing on the wall and added a link for free apps.

Fear not, though, loyal TiPb Readers. We have the link to browse all 90 pages of free apps, over 1850 apps in total, right here. Go on, browse those free apps, don't let the man keep you down. Browse all Apps

Update: Turns out that you can, in fact, stop the signal. The "Browse all free apps" listing linked above contains, well, a lot of apps that ain't free. Could it be that Apple got sick and tired of developers listing their apps as free to move up the top apps chain, then switching to for-pay to bring in the cash? Our best guess: Apple must not have a good, automatic way to categorize "free," so they took the above link down to tweak the store.
