Hey!
Here is a list of my favourite free 3 iPad/iPod/iPhone games!
1. Clash of Clans
Clash of Clans is an awesome game where you gather resources, raid other people's villages, and upgrade defenses and troops!
2. Boom Beach
Boom Beach is made by the same company as Clash of Clans (Supercell) and is pretty much the same thing except you can only deploy troops on enemies beaches!
3. Disco Zoo
This game is made by NimbleBit Games! You gather money from your animals, use your money to rescue more animals, and then you buy new areas to rescue! There are over 40 different animals you can rescue!
