Puzzle Trouble is a Tetris variant with coloured squares which fall from
the top of the screen. The player’s goal is to arrange three ore more blocks
in a vertical or horizontal line. Then the blocks vanish and the player gets
points, An interesting modification of the original concept is that not only
the falling blocks can be manipulated but also the blocks already on the game
field. To do so the block is marked with space and moved with the arrow keys.

Additionally the player can earn himself a joker by recreating a block
structure which is shown on the top left, e.g. an “L”. In the multiplayer mode
a part of the erased blocks appear on the opponent’s side to hinder his
progress.
