Kitty Cat Merge, also known as Cats Drop, is a merge game similar to 2048 that features cat heads instead of numbered blocks. The player's must evolve smaller types of cats to become larger types via merges in a clear container.
When the player drops a head, it rolls and bounces around realistically. As a result, the player must make each drop carefully to prevent unintentional positioning of a head. That said, the player can shake the container once for free and additional times by watching ads.
