For some people, the world is divided into black and white, because they are color blind and do not distinguish colors.
Imagine that you ended up with such a world.
But this does not mean that it has become less interesting, because it has ceased to be colorful.
To prove this, we present you the game Black and White Dimensions.
This is a mahjong pyramid made in three-dimensional space.
It consists of black and white square blocks.
Remove by two elements, they must be with the same pattern, but different colors - this is the main condition.
The game has forty levels, gradually becoming more complex.
To rotate the pyramid, use the arrows to the right and left of it.
