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 in-app you will not get ads before the hints. Enjoy! @BartBonte

Zen Pipe's advantage is ads (none vs shown) and iOS requirement (9.0 vs 13.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.
