1v1 PvP. Pick any amount from 0.01 to 500 SOL. Your wallet is charged the amount plus a 3% service fee. An opponent matches. Two candles race on a chart for 10 seconds. First to hit the take-profit line wins. Winner takes the full pot (2x the buy-in amount).
Example: 1 SOL duel. Each player pays 1.03 SOL. Winner gets 2.00 SOL. Platform gets 0.04 SOL (2% x 2). Jackpot gets 0.02 SOL (1% x 2).
Battle royale. Multiple players enter a lobby at a fixed buy-in. Once the minimum player count is reached, the game starts. Every 4 seconds, one or more players are randomly eliminated via Switchboard VRF. Last player standing wins 88% of the total pot.
| COMPONENT | PERCENTAGE |
|---|---|
| Winner | 88% |
| Daily Jackpot | 10% |
| Referral Pool | 1% |
| Platform | 1% |
Every game contributes to a daily jackpot that draws at midnight UTC. Ticket allocation:
1% of every duel fee and 10% of every royale pot goes directly to the jackpot vault.
All outcomes are determined by Switchboard On-Demand VRF (Verifiable Random Function) running on Solana. Randomness is generated inside Intel SGX Trusted Execution Environments. No party — not players, not RUMBLR, not the oracle operator — can predict or manipulate results.
Every game result is verifiable on-chain via Solscan.
All player funds are held in Program Derived Address (PDA) vaults controlled by immutable smart contract code. RUMBLR never has custody of player funds. Payouts are automatic and instant.
From round 2 onwards, alive players can "jeet" (cash out early) at escalating multipliers based on how many players remain. Multipliers range from 0.75x (early jeet) to 2.50x (late jeet when few players remain). The jeet payout comes from the game pot, reducing the final winner's share.
Phantom, Backpack, Magic Eden, and any Solana wallet that supports the Wallet Adapter standard.
