The same rule, with depth
A clue counts mines in all touching cubes: faces, edges, and corners. An interior cube has 26 neighbors: eight in its own layer, nine above, and nine below. Edge and corner cubes have fewer.

How to play in 3D
Mines can be above and below you. Explore a real volume, inspect its layers, and connect clues across three dimensions.
Reveal every safe cube to win. Each number counts touching mines. Flag squares you believe contain mines; opening a mine ends the game.
Rotate the volume; play a layer
Drag the volume to rotate it, or use its rotation buttons. Selecting a cube in the volume brings its layer into view. Reveal and flag squares in the flat layer board, where every cube stays easy to reach.
Connect clues across layers
Point at or focus a square to highlight its neighbors. Use the layer controls to inspect clues above and below. A zero opens safe space across all three dimensions, not just the visible layer. The opening is safe; later moves can require a guess.
