krank is a game of dexterity, being somewhere between Breakout and billiard, where the aim of each level is to shove floating stones towards compatible static stones. You control a short chain of stones with your mouse to achieve that.

While the game's visual and aural style is as simple as the rules are, there is no shortage of variety. Different level layouts provide enough challenge and different gameplay elements (the interactions between different types of floating stones with different types of static stones) are introduced at a reasonable paste. If you find the hardness curve too flat or simply don't like one level: the game permits you to skip one level ahead the last finished one.

Another important aspect, which keeps me playing, is the variety of look and sound.
