On-chain mini-arcade with provable randomness

Clicks call contracts. Randomness comes from future blocks. You can audit odds, edge, and payouts.

Fairness

No black boxes. Here’s the model you’re playing against.

Commit → future block

Rounds commit now and reveal after a target block. We mix its blockhash with prevrandao. UI waits until the seed is live.

On-chain clicks

Every reveal is a transaction. What you see is produced by the contract. Front-end can’t peek or reorder.

Transparent edge

Multipliers use fair odds × (1 − edge). Caps are explicit. Numbers sit on-chain, not in a spreadsheet.

Bankroll & payouts

Owner funds a pool. Wins debit it and credit your pending balance. Withdraw when you want.

FAQ

Short and clear. No fluff.

Why do I sometimes see two tx at the start?

If you want the first card/tile face-up before guessing, we “prime” once the seed is ready. That’s a separate tx. You can skip priming and guess blind if you want fewer clicks.

Where do my winnings go?

Cash-out credits your on-chain pending balance. Hit “Withdraw” inside any game to move it to your wallet.

What about multi-wallets?

Entries are priced and rounds are independent. When we add leaderboards, we’ll score over short windows and use anti-sybil rules.
