Analyse de l'application black (game) pour le 8 août

The sequel to my 'yellow' and 'red' games is here! Can you make the screen black 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 in-app purchase you will not get ads before the hints. This is the third game in my color puzzle series. There are already 7 color games each with 50 new levels. Enjoy! @BartBonte
