Oh, no! Another game of blocks... but wait, this one is different!
Each block is formed by the composition of three primary colors: red, yellow and blue. In this game you change the color of the blocks by adjusting the right amount of these three primary colors. If you group four blocks, in line or in column, this group of blocks is removed from the game.
Instead of playing with three primary colors, you can change the game mode and play with just one color: red, yellow, blue or sepia. In this case, you change the hue of the blocks.
Isnt it interesting?
