Your iPhone can be a great time killer as long as you have the right apps for it. We have all played those games that require you to find the differences between two pictures. 3 Differences is a free game that challenges you to find 3 differences among 3 pictures. There is also a time limit to push you to find the differences faster.
3 Differences has a simple interface. Just touch where you find differences. Be careful not to touch the wrong places or you will strike out. The game has a 2 minute time limit, and you get bonus points for solving challenges fast. The game has enough free levels to keep you busy for a while. But we would love to see more added.
3 Differences is simple to pick up and fun to play around with. It needs plenty of more levels. Nice to play once in a while though.
