Merge same icon and color tiles to evolve your eggs to the next level. The key to make built-up tiles is to merge several tiles all at once, which will get you a wildcard tile that can merge any color tiles. But, when the board becomes full, it’s game-over, so you should be careful not to be too greedy. This game has very simple rules, and there is no time limit. Everyone can have fun playing. [Features] - Autosave - Next tile notification - Help star button (tiles change to the wildcard) - Score ranking [Premium Package] - Remove Ads - UNDO
