Ju

Ju is a puzzle game with 80 levels. You move a green cube across a maze to a red end area, choosing your route carefully to avoid traps such as endless loops. Each move sends the cube sliding until it hits a block or wall.

Four rule sets

The levels are divided into four groups of 20, each adding a different rule:

• Basis rule (levels 1–20): Move the green cube to the red end area.
• Following rule (levels 21–40): The end area moves when you try to move the cube, so you must decide whether to focus on moving the cube or the end area.
• Twins rule (levels 41–60): Guide two green cubes to two end areas. If the cubes touch, they become one entity.
• Rule (levels 61–80): Reach the end area before any of the green areas moves to the left-end-area. You must also move onto every blue block once, or the end area will be blocked.

The name Ju comes from a piece in Chinese chess. The game's idea began with adapting the rule of JU to a simple maze.
