Swap Tiles is a fun app for iOS devices that trains and exercises your brain
Swap Tiles is a brain game developed by Liam Chase of Orandasoft. Swap any two tiles on the screen to swap them and when three or more of the same tile make a row, then they join together. Get to the highest score you can by making hundreds of possible combos. At least three empty tiles are needed to generate new tiles. Compare your score with your friends and compete to be the best on the worldwide leaderboard.
