Pick how many mines to hide, then open tiles one at a time. Each gem raises the multiplier; a mine ends it. The board is fixed and published as a commitment before your first click, and checked against the oracle afterwards.
The house publishes a Merkle root of the finished layout on chain before your first tile. Every answer it then gives comes with a proof against that root, which this page checks in your browser — so a lie about a tile is caught on the click, not afterwards.
When the round settles, the oracle word becomes public and the contract recomputes the board from it. If that does not match the root the house committed to, the round is voided and your stake returned. A dishonest commitment is not something to argue about later — it is a state the contract can see.
Opening a round names a one-round key your browser generates and keeps in memory. It can do exactly one thing — order tiles in that round — and never touches funds. That is what lets you click through a board instead of signing twenty five times.
A cash-out after k gems pays the edge divided by your chance of having survived them, so one mine and twenty four mines return exactly the same 99% over time. No mine count is a better bet than another; they only differ in how wild the ride is.
