Unlock Block - Puzzle

Unlock Block - Puzzle is a sliding block logic puzzle game where players maneuver wooden blocks within an enclosed grid to clear an escape path for a special blue block. By sliding horizontal blocks left and right, and vertical blocks up and down, you untangle tight grid jams and guide the key block out through the grid exit door.

How to play

On desktop, click and drag wooden blocks along their aligned axes to shift their positions. On mobile screens, swipe blocks using your finger. A common beginner pitfall is sliding blocks randomly back and forth without identifying which blocking piece directly obstructs the main exit pathway.

Tips

• Identify the primary blocking piece closest to the exit door and work backward to clear space for it to slide away.
• Move long 3-unit vertical blocks to grid corners first to open up central horizontal maneuvering corridors.
• Aim to solve levels in the minimum number of moves to earn gold 3-star puzzle completion trophies.

Who it's for

Ideal for sliding puzzle fans, logic enthusiasts, and casual brain-teaser lovers seeking satisfying spatial problem-solving on desktop browsers or mobile touchscreens. If it clicks with you, try Color Hoop Stack or Falling Blocks - Tetris Game next.
