The follow-up to my "yellow," "red," and "black" games is now available! This fun and exciting game is called "blue". In 50 stages, you will need to turn the screen blue in order to pass and survive. Every level has a distinct logic.

However, if you got stuck in the middle and will need a hint, it won't be easy. To acquire a hint, use the light bulb button that will eventually appear in the top right corner of each level, which has many hints available.

Additionally, you will not see advertisements before the hints if you use the in-app premium unlock.
