Unikitty! Rainbow Rage is a very classic puzzle game. If you are a fan of this kind of game, don't miss this game. A tile-matching video game is a type of video game where the player manipulates tiles in order to make them disappear according to a matching criterion. In many tile-matching games, that criterion is to place a given number of tiles of the same type so that they adjoin each other. That number is often three, and these games are called match-three games.
