EMBER³ – 3D Minesweeper

Minesweeper, with a whole new dimension.

EMBER³ turns the familiar logic puzzle into a glowing cube. Rotate it to explore every side, slice through its layers and use the numbers to find the hidden mines.

Each number counts mines among up to 26 neighboring cells, including diagonals across layers. Reveal every safe cell to win.

Logic you can follow

Boards are checked by a logical solver before play, starting from your first reveal. Mines stay fixed for the rest of the game.

If you get stuck, request a hint: it highlights a certain move and explains the clues behind it. Three small layer diagrams help you inspect the relevant neighborhood. A built-in solving guide introduces the rules and more involved deductions.
