The three board shapes are three different games
Square, hexagon and triangle change how many neighbours a number counts — six, eight or twelve. That changes what a number tells you and how far a cascade runs.
Updated 31 August 2026
The rules are Minesweeper’s and have not been touched. The board shape is not a skin, though: it changes the arithmetic underneath every number you read.
| Shape | Neighbours | What changes |
|---|---|---|
| Square | 8 | The original. Everything you already know applies. |
| Hexagon | 6 | No diagonals. Numbers read lower across the whole board and cascades run wider. |
| Triangle | 12 | Alternating up and down; every triangle sharing a corner counts. Numbers run high and each one says a great deal. |
How to adjust
- Hexagons: a 1 is far more informative than a square-board 1, because it is one mine among six rather than among eight. Open aggressively — the cascades are generous.
- Triangles: stop reading numbers as "how dangerous" and start reading them as "how much information". A 5 among twelve neighbours is a weak constraint; a 1 or a 2 is enormous.
- Do not carry square-board pattern recognition across. The familiar 1-2-1 shapes do not mean the same thing.
The first click is always safe, on every shape. Open in the middle, not the corner.
Is this wrong?
Then say so
These are written from the games’ own balance references, but a number that was true in one build can stop being true in the next. If something here does not match what you are seeing, that is worth knowing.
