Klax — About this game
The paddle can hold five tiles, giving you a short buffer while planning the stack below. Missing incoming tiles fills the drop meter, and an overcrowded well can also end the game. A first match may expose another matching group for a chain, so consider what will fall after a clear. Different wave requirements change whether you should prioritize lines, score or another displayed target.
