John Adventure

John Adventure is a falling-block puzzle game developed by Sachen and published by Watara. Each stage takes place inside a bottle filled with dancing objects that must be destroyed.

Pairs of pieces fall from the top of the bottle. Match four pieces of the same color in a row to make them disappear, and clear all target pieces to complete the stage. If the pieces reach the top of the bottle, the game ends.

The game includes 20 stages and three play speeds, and was released in 1991 for the Watara/QuickShot Supervision and Watara Supervision.
