Play for the pot

Every game on ROBIN Arcade can be played for free or for the pot. A game for the pot costs about $0.10 in $ROBIN, rolls the instant jackpot and counts for the weekly prize pool. A contract on NEAR runs every rule: no owner, no withdraw button.

On-chain, for real

Every game you play for the pot is a transaction on NEAR. Payments, the split of every play, jackpot draws and payouts are recorded on-chain and can’t be changed by anyone. The prize pool contract has no owner keys, so its rules can’t be changed either. Vault Cup scores are checked by the contract itself, which replays every move.

      The rules, as the contract runs them
      1. Free or for the pot. Every game can be played for free. A game for the pot is paid in $ROBIN: the exact price is shown above and in every game.
      2. Instant jackpot. Each game for the pot has a 1 in 2,000 chance to win the jackpot on the spot. Free players with an account get a few free rolls a day at 1 in 200,000.
      3. Burned on every game. 15% of each game for the pot goes to an address nobody controls. The more people play, the less $ROBIN there is.
      4. The weekly pool. Half of every game for the pot fills the weekly pool. 60% goes to the Vault Cup top 10, 40% to the 10 most active players. Ranks get 25, 18, 13, 10, 8, 7, 6, 5, 4 and 4% of each part.
      5. Moves, not scores. Vault Cup players send their moves. The contract replays the whole defense with the game's own rules, so a score cannot be invented.
      6. No owner. Anyone can close a finished week, and the contract has no withdraw method and no keys.
