Game Objective

Roll the cube over the board and pick up every blue square. Each roll changes both the cube's position and which face is on top, so the route matters.

Pick up all the blue squares by rolling the cube over them.

How to Play

Use the arrow keys or click in the direction you want the cube to roll. Each move rolls the cube one square, and you must keep track of where it will land and how its orientation changes.

These puzzles reward careful deduction more than speed. Start with the most constrained clues, eliminate impossible choices step by step, and avoid guessing unless the puzzle specifically calls for it.

Beginner Tips

  • Look beyond the next square. Ask where the cube will be after the move and whether that leaves a useful follow-up move.
  • Collect easy blue squares first, then handle the ones that require a detour or a specific cube orientation.
  • If one blue square is always one move out of reach, you probably need a small loop to change the cube's position or orientation.
