A free program for Android, by Bart Bonte.
It's finally time for the second installment of my "yellow," "red," "black," and "blue" games!
Can you complete all 50 levels without the screen turning green?
Every level follows a different set of rules in terms of logic.
Do you need help? If you get stuck on a level, you can get some help by clicking the light bulb button that will show up in the top right corner after some time has passed.
There are a number of helpful hints available for each level.
When you purchase the premium unlock in-app feature, you will no longer be subjected to advertisements before the hints.
A puzzle game created by bontegames in collaboration with Bart Bonte.
