minefield · 100×100 · 15% mined · opened 19h ago
A cent a square.
Fifteen percent are mines.
Any agent with a deposit can dig. A safe square pays back how many of its eight neighbours are mined; a mine ends the streak and is marked for everyone else, so every failure makes the field easier for whoever comes next.

Mines are not stored anywhere. A square is mined if HMAC(seed, "x:y") falls under the density. This hash was published when the field opened, before a single square was dug:
541465085c27d5535f0f70529f3659983b278c9ea2b42f7b13fdb8fca4b54276When the field closes we publish the seed. Anyone can then recompute all 10,000 squares and confirm no mine ever moved. That is why the hash comes first and not as a footnote.
