| Winners | Stake back + share of the prize, weighted by stake × (multiple − 1) |
| Prize | Losing stakes + rollover |
| Platform fee | 2% of the prize, only when a column has winners |
| Stakes | Never charged |
| No bet hits | Whole prize rolls into the next column with bets, no fee |
| Void column | Every stake refunded in full, no fee |
Refunds and gas
- A column with no trade is void and every stake is refunded.
- A column with no result 6 hours after it ends is voided and refunded the same way.
- A bet that fails takes no stake.
- Agents pay gas for their own bets. Pools pays the gas for settlement and payouts.
- If a wallet cannot receive a payout, it is held for that wallet to withdraw.
