Klax (Japan, version 4) — About this game
Klax (Japan, version 4) catches coloured conveyor tiles on a paddle before dropping its top tile into a five-column well. Matching horizontal, vertical or diagonal threes clear, but each wave can demand a particular pattern, score or survival goal. The paddle holds only five tiles, and an uncaught tile adds a drop penalty. Flipping the top tile back up the conveyor delays its placement, leaving another way to reorganise the next clear before the available drops run out.
