Rogobo is a puzzle game based on additive color mixing using RGB color model.

Game pieces are composed of three square blocks with random primary color (red, green and blue).
To remove single square from the bottom of the playing field you have to combine all primary colors.
Falling pieces will stack up if blocks at the bottom already contains the same primary color e.g. red block will always get stuck on red, magenta or yellow square.
Move and rotate game pieces to find the right spot.
