We built RUMBLR because we were sick of crypto casinos where the house always wins. The Royale was our answer — a battle royale where players fight players, not algorithms.
But we heard you. Waiting for 20 or 50 players to fill a lobby takes time. You want action now. So we built Duels.
How RUMBLR Duels Work
It\'s simple. You pick an amount — any amount from 0.01 SOL to 500 SOL. Your duel goes live. Someone accepts. Two candles race on a chart. One hits the take-profit line. Winner takes the entire pot.
The whole thing takes 10 seconds from countdown to payout.
The Economics
When you enter a 1 SOL duel, your wallet is charged 1.03 SOL. That 3% service fee is taken upfront. Your opponent pays the same. The winner walks away with a clean 2.00 SOL. No hidden rake. No house position. The platform takes its cut before the game starts and never touches the pot.
This is the same model used by DegenCoinFlip and other proven PvP platforms. The difference? RUMBLR duels aren\'t a coin flip. They\'re a visual, high-tension candle race with the dopamine of watching a volatile chart.
Provably Fair
Every duel is settled by Switchboard VRF — the same verifiable random function that powers our Royale eliminations. The randomness is committed when your opponent accepts, revealed when the crank settles. Neither player, nor us, nor the crank operator can influence the outcome.
The smart contract is non-custodial. Your SOL goes into a PDA vault controlled by immutable code. Not our wallet. Not anyone\'s wallet. Code.
Jackpot Tickets
Every duel earns you tickets in the daily jackpot. The math is straightforward:
• 1 ticket per 0.1 SOL wagered
• 1 bonus ticket if you win
• 1 bonus ticket if you share your result to X
1% of every duel\'s fee goes directly to the jackpot vault. It compounds every game, every day. At midnight UTC, one wallet gets the whole thing.
Duel While You Wait
The real power of Duels is how they integrate with Royale. Joined a 0.50 SOL Royale lobby with 8 out of 20 players? That might take a few minutes to fill. In the meantime, fire off some 1v1 duels. Stack jackpot tickets. Keep the action going.
RUMBLR is becoming more than one game. It\'s a PvP ecosystem where there\'s always something to play.
What\'s Next
Duels are in beta testing right now. The smart contract has been through a 22-vector security audit. We\'re running final tests on mainnet before opening to the public.
