1. What's the difference between creative and survival modes?

Minecraft Pocket Edition: Top 10 tips, hints, and cheats!

Minecraft Pocket Edition has two main game play modes and depending on your gaming style, you may heavily prefer one over the other. Creative mode gives you endless supplies of all inventory, there are no monsters and mobs to combat, and you can craft and create until your heart's content. If you like game play similar to that of the Sims, you'll most likely prefer Creative mode.

Survival mode features both night and day and you start off with nothing. You'll need to harvest resources in order to build even simple things such as tools and work tables. You also have to beware of angry mobs and monsters that come out at night. If you prefer a challenge, Survival mode is what you want.
