Cube Sweeper: 3D Minesweeper

Cube Sweeper: 3D Minesweeper takes the flags, numbers and logic of Minesweeper and places them on three-dimensional solids. You rotate and zoom the board to read clues across faces, around corners and through tunnels, where a tile can have more than eight neighbors. A 9 clue is possible, and solving one earns an achievement. Every board is certified solvable by logic alone, with no forced guesses.

Read the solid

Clues can refer to tiles you cannot see from your current angle. Hold Ctrl and right-click a tile to outline all its neighbors; the outline remains as you rotate the board. Learning to read how the solid’s faces connect is central to solving its puzzles.

Modes and difficulty

Four tiers scale both the shape and the difficulty, from small boards to dense Expert solids with challenging folds and tunnels. Three modes are available at every tier from the start:

• Classic: play a straightforward mine-sweeping board.
• Gem hunt: use clues to find and uncover hidden gems.
• Expedition: combine mine-sweeping and gem hunting; recovered gems become Lifelines that absorb a single mine hit.

There is no undo. A mistake ends the attempt, but because every board is solvable, you can identify what you missed and replay it from the start.

Boards to solve

Generated boards are fresh and certified fair, alongside handcrafted, named boards. A new daily board resets each day, with streaks, precise times and per-tier best times to pursue. You can also make custom boards by setting their size, carving, mine density and gems, then share them with board codes. Codes also let you send someone the exact board you played and challenge them to beat your time.

Learning and achievements

The 25-chapter Learning Journey teaches the game through hands-on boards, from your first click to reading whole solids. Its final section covers strategy patterns such as 1-2-1, first on flat surfaces and then across an edge. Hints show a provable move but leave you to make it yourself. The game has 24 achievements, including “Leave No Gem Behind,” “The Hurt Lockerer” and “The Impossible Made Unlikely.”
