Vault
Crack a 25-tile grid. Every gem you uncover lifts your multiplier — but the mines are placed server-side and hidden. Choose how many mines to face (1–24) to set your own volatility, then bank any time or push for one more tile.

One tile at a time.
Reveal to climb
Every safe tile you open raises a cumulative multiplier along a published ladder. The more you reveal, the bigger the bank.
Dodge the mines
A player-chosen number of mines is hidden on the grid before you start — placed server-side by a provably-fair shuffle, revealed only when the run ends. Hit one and the run is over.
Set your own risk
Pick 1 mine for a slow, steady climb or 24 for a single do-or-die tile at a huge multiplier. The RTP stays 97% at every setting — you choose the volatility.
The mines are set before you pick.
Before a run starts, the server publishes a hash of the seed that fixes every mine position. When the run ends it reveals the seed — anyone can recompute the exact mine layout with a provably-fair Fisher–Yates shuffle and confirm nothing moved. Outcomes, balances and the hidden layout live on the server; the client only renders.
