Puzzle Uo Poko (c) 1998 Cave.

Uo Poko is a puzzle game for one or two players (co-operative). The aim is to clear the screen of coloured glass balls by dropping like-coloured balls down onto them. Connecting three or more like-coloured balls creates a chain reaction and causes them to disappear.

Balls are launched into the play area via a joystick controlled 'pinball-plunger' and as in Pinball, the further the plunger is pulled back, the further the coloured ball will travel. Mastering the strength and distance required is essential in order to drop each ball accurately onto its target. To allow players to learn how to use the plunger, the first two stages feature a guide line which shows exactly where a ball will drop. From the third stage onwards, players must use their judgement alone.

Bonus points are awarded if a stage is completed quickly enough. If too much time is taken, however, the bottom of the stage will start to rise, pushing the balls already in play towards the top of the screen. If the top of the screen is reached, the game is over.

Uo Poko features thirty stages of play.
