Arena

Last one standing takes the pot

Arena is a last-one-standing brawl where every fighter in the pit is another player with real money on the line. Everyone shares the same live round: you stake SOL, ETH or FUEL, the pit fills while the timer runs down, and when it hits zero one fighter is left standing and takes the pot. This is player versus player — the house never plays against you, it only takes a fixed cut of the pot.

How to play

  1. Pick your token and your stake. Each token runs its own pit, so you are matched against everyone else betting that token — SOL players fight SOL players.
  2. Get your bet in before the timer runs out. Every round has a 60-second betting window, and you can top up your stake at any point while it is open.
  3. Your stake is your odds. The pot is split into ticket ranges proportional to what each player put in — stake a quarter of the pot and you hold a quarter of the tickets.
  4. Watch it play out. The winner is decided the moment betting closes; the brawl you see is how that result is revealed, not what decides it.
  5. The last one standing takes 95% of the pot, credited as soon as the round settles.

Is it fair?

Every round is committed before anyone bets. When the round opens, the server generates a secret seed and immediately publishes its SHA-256 hash — so the seed is locked in public before a single stake is placed, and cannot be swapped once the house can see who bet what. When betting closes, the winning ticket is derived as SHA-512 of the server seed, the public seed and the round id, taken modulo 1,000,000, and whichever player's stake-weighted range contains that ticket wins. After the round resolves, the server seed itself is revealed: you can hash it yourself, check it matches the hash published at the start, and recompute the winning ticket from scratch. The fight animation has no influence on any of this — it is a dramatization of a result that was already fixed.

Stakes and payouts

Stake limits are per token: 0.001 to 100 SOL, 0.0001 to 5 ETH, or 200 to 200,000 FUEL. The house takes a flat 5% of the pot and the winner receives the remaining 95% — that rake is the entire house edge, and it does not change with the size of the pot or the number of players. A round needs at least 2 players to resolve; if only one bet lands before the timer expires the round is cancelled and that stake is refunded in full.
