The sequel to my 'yellow', 'red', 'black' and 'blue' games is here! Can you make the screen green in 50 levels? Each level has its own logic. Do you need help? Use the light bulb button that will appear after a while in the top right of each level to get a hint. There are multiple hints for each level. With the "no ads" in-app purchase you will not get ads before the hints. A Bart Bonte / bontegames puzzle game. Enjoy! @BartBonte
