How to Play Klax
Quick start
Catch coloured tiles on the paddle and drop them into the five-column bin to form horizontal, vertical or diagonal groups of three or more. Start with simple horizontal Klaxes and avoid carrying the full five tiles. Flip unwanted tiles back onto the conveyor to create room, then watch each wave objective because later stages may demand a score, a number of Klaxes or a particular pattern.
Controls
Left/Right: move the paddle. Down: drop the bottom carried tile into the bin. Up: flip the top tile back onto the conveyor. A/B/C perform drop or flip according to the selected control option. Start: begin or pause. The paddle can carry up to five tiles, so release them in the needed order.
