Minimum bet: 3. Coin Flip never takes raw Qu — QSC or STAR only. Every bet is also capped at whichever is smaller of your own balance, the shared bonus pool's payout capacity (QSC only), and a flat 100,000-unit maximum per bet — the "Max" chip always reflects the current limit.

Refilled automatically — nothing to click here. A standalone off-chain process (see the randomprovider tool alongside this project's source) watches this reserve and calls Qusino's permissionless, free refillRandomBank the moment it runs dry, buying fresh entropy from Qubic's RANDOM contract out of the bonus pool shown above. If Reserve filled ever stays at zero for a while, that process isn't running against this node right now — not something a bet or a page reload here can fix.

How the randomness works

Coin Flip does not use a client-seed provably-fair scheme. Instead, the Qusino contract buys entropy in bulk from Qubic's RANDOM contract and caches it in an on-chain "Result Bank" (a per-game pool backed by a shared reserve). Each flip draws instantly from that pool, then the slot is refilled from the reserve so no value is ever reused. The draw is re-hashed with call-specific context (invocator, tick, pool nonce) before it decides heads or tails, so outcomes can't be predicted ahead of a bet.
