No real money. No signup. No risk.
Your balance lives in this browser only via localStorage — it isn’t real and isn’t worth anything. Reset it any time from the controls panel. Every bet still uses real provably-fair machinery (HMAC-SHA256), so you can verify outcomes the same way you would on Stake, Shuffle or any of the other casinos WinLogger tracks. Click Provably Fair in the controls to inspect, rotate or audit your seeds.
Slide — Rules, Math & Receipts
How to play
Set a target multiplier — anything from 1.01× to 1,000,000× — and press Slide. The reel travels and stops with one multiplier under the pin. Land on or above your target and you win bet × target. Land below it and the bet is lost.
The payout is always exactly your target, so the only thing you are really choosing is how often you want to win. There is no timing and no cash-out: the whole decision happens before the reel moves.
Math
win chance = 0.99 / target
payout = target
2× lands 49.5% of the time, 10× lands 9.9%, 100× lands 0.99%, and 1,000,000× lands roughly once every million rounds. Multiply chance by payout and you get 0.99 at every single target — a 1% edge, identical whether you play it safe or go for the ceiling. Nothing about picking a big number gives you better value, it just changes the shape of the variance.
The cards either side of the pin are drawn from the same distribution, so the reel looks like the maths actually is.
Provably fair, with a public receipt
Each round takes HMAC-SHA256(server_seed, client_seed:nonce), reads the first 8 hex characters as a float, and runs it through the formula above. The server seed is committed as a hash before you bet, so the outcome cannot be picked afterwards.
Every settled bet is written to a public receipt with its bet size, target, result, payout, seed hash, client seed and nonce. The link appears under the reel. When you rotate your server seed, the revealed seed is attached to all the bets that used it — and from that moment the receipt page recomputes the result in the visitor's own browser and shows whether it matches.
Worth saying plainly: this is play money and the whole game runs in your browser, so the receipt is a record rather than an authority. But it publishes every input that a real casino keeps to itself until you go asking — which is the part worth copying.
