The write-up

Bark Dice is a Bitcoin dice game built on Ark. Pick your odds, send your stake from a Bark wallet, and receive your winnings automatically—no account or custodial player balance required.

Each bet uses a cryptographic commit-and-reveal scheme: the house commits to a secret seed before you choose yours, then reveals it after the bet resolves. You can independently verify the commitment, roll, and payout in your browser or with our command-line verifier.

Players can choose between four risk levels, from a 50% chance at a 1.97× payout to a 2% chance at 49.25×. The house edge is a transparent 1.5%, and payouts include the original stake.

Behind the game are bankroll reservations, automatic refunds for late or duplicate payments, and settlement tracking designed to prevent duplicate payouts. A live house dashboard and an animated terminal client make the whole flow visible.

It’s a playable demonstration of Ark payments: small Bitcoin transfers powering an interactive application, with transparent rules and independently checkable results.
