How it works

Each roll draws a number from 0.00 to 99.99, every one of the 10,000 values equally likely. Drag the slider to choose a target, roll under it or flip to roll over it. A smaller win chance pays a bigger multiplier, and every target returns the same 99%.

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

Claim your daily chips. Holders of the project's coin get more chips, a bonus on wins and the holders' table.

iii.

Set a win chance from 0.10% to 98%, choose a stake and roll. Every result can be re-checked below.

Fairness mapping and RTP

Each roll uses one nonce of your seed pair: the first float of HMAC_SHA256(serverSeed, clientSeed:nonce), read as b0/2^8 + b1/2^16 + b2/2^24 + b3/2^32 from its first 4 bytes.
The roll is r = floor(float × 10000), a whole number from 0 to 9,999, shown as r / 100 (0.00 to 99.99).
Roll under target t wins when roll < t, which is 100·t of the 10,000 values. Roll over t wins when roll > t, which is 9999 − 100·t values. Call that count W; the win chance is W / 10000, allowed from 10 (0.10%) to 9,800 (98%).
The multiplier is floor(99,000,000 / W) / 10,000, so 0.99 ÷ chance rounded down to 4 decimals. The payout on a win is floor(stake × multiplier) whole chips. The same code runs on the server and in the verifier on this page.

RTP is W × floor(99,000,000 / W) / 10^8 for each target, before payouts are rounded down to whole chips. Rounding matters only for small stakes at low multipliers (for example a 10-chip stake at 98% wins 1.0102× → 10 chips back), so bigger stakes get closer to the exact figure.

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.
