Mosaic is a puzzle game about simplicity, but that doesn't mean that it's easy. If you know the game Lights Out, you will already understand the premise of Mosaic. To win, you need to turn on all the color squares on the screen. Completely free. No in-app purchases or ads. Just play the game the way it is intended to be played. Three tough modes. Play through the Regular, Zen, and Challenge. Zen mode is an unlimited, un-timed, relaxing mode to play through the game peacefully. Challenge mode is exactly that: the hardest, most challenging version of Mosaic. Added a little tutorial on the first level to help new players better understand how the game works. Speed up tile animations just a pinch Made a very slight delay between flipping over the last tile and when the win screen displays.
