How it works

Choose how many of the 25 slabs hide a magma mine (1 to 24). Every slab you lift that holds an amethyst raises the multiplier. Cash out whenever you like. Lift a mine and the round's stake is lost. Find every gem and you are paid out automatically.

Try the demo with 1,000 local chips, or sign in with your wallet (a text signature, never a transaction) and claim your daily chips.

Set a stake and a mine count, then start. The layout is fixed the moment the round starts and stays on the server until it ends.

Lift slabs one by one. Cash out any time after your first gem. A signed-in round survives a page reload, so you can pick up where you left off.

Fairness mapping and RTP

Each round uses one nonce of your seed pair. The bytes are HMAC_SHA256(serverSeed, clientSeed:nonce), then clientSeed:nonce:1, :2, read 4 bytes per float: b0/2^8 + b1/2^16 + b2/2^24 + b3/2^32.
The 25 slabs are numbered 0 to 24, left to right and top to bottom. Start with the list [0, 1, …, 24]. For i = 0 … 23: j = i + floor(float_i × (25 − i)), then swap positions i and j (a Fisher–Yates shuffle that uses floats 0 to 23).
With m mines, the first m slabs of the shuffled list are the mines. The verifier below shows every slab's place in the list, so you can check a round for any mine count.
After k gems, the multiplier is 0.99 × C(25, k) / C(25 − m, k). The payout is floor(stake × 99 × C(25, k) / (100 × C(25 − m, k))), worked out in whole numbers. The same code runs on the server and on this page.

99.00%RTP for every mine count and every cash-out point (house edge 1%). Exact before rounding down to a whole chip.

C(25−m,k) / C(25,k)the chance of lifting k gems in a row with m mines. Multiplier × chance = 0.99, always.

5,148,297×top multiplier: 12 or 13 mines with every gem found.

Why the RTP is the same whatever you do: the chance of surviving k picks does not depend on which slabs you choose, so every way of playing (stop after 1 gem, after 5, or go for all) returns 99% on average. The only losses beyond that come from rounding the payout down to a whole chip. Holder win bonuses (+2/+5/+10% of profit) come on top for holders.

Holder perks

Sign in with your wallet to keep chips, claim daily chips and appear on the leaderboard. Holding the project's coin unlocks bigger daily chips, a small bonus on wins and the holders' table.

Daily chips reset at 00:00 UTC. Claiming on consecutive days adds a streak bonus (+10% per day, up to +50%). The holder tier is read from your wallet's token balance on Solana at sign-in and every 10 minutes. Perks are bonus play only: chips have no cash value.

Provably fair

Every result is decided on the server from seeds you can check. Before you play you see the SHA-256 hash of the server seed. Each play uses HMAC-SHA256(serverSeed, clientSeed:nonce), and the game's mapping below turns those bytes into the result. When you rotate, the old server seed is revealed, so you can re-run every past result yourself.
