Klax — About this game
The North American Mindscape edition presents Klax on a conveyor receding into the screen. Catch patterned tiles on a paddle and drop them into five columns to make matching groups of three horizontally, vertically or diagonally. The paddle and columns have limited capacity, and missed tiles fill a drop meter. Each wave asks for a specific goal, such as diagonals, points or a number of caught tiles. Throwing a tile back up the rails buys time to reorganise, while clever placements can trigger several matches as unsupported tiles fall. Choose 1 PLAYER, press START and begin with Wave 1. Catch a tile by moving under its rail, then press A to drop it into the chosen column. Read the wave goal before building a horizontal or diagonal setup; use Up to return a tile when the paddle becomes crowded.
