Results are demo simulations, not a provably-fair protocol. Wins and losses update your shared demo balance, which is stored only in this browser and has no value.

How to play Coin Flip

  1. Choose Coin Flip in the demo arcade and enter a wager between 0.01 and 1,000 demo credits.
  2. Pick heads or tails from the menu, then press Flip coin.
  3. The server flips a fair coin with Node's cryptographic random number generator. If it matches your pick, you win 1.96× your wager back (a profit of 0.96× the wager); otherwise you lose the wager. The result and your updated balance appear immediately.
  4. Want to flip against another player instead of the house? Signed-in players can open a PvP coin flip room on the homepage and play head to head for ROLL points.

Coin Flip payouts and multipliers

There is only one outcome to bet on, so there is one payout.

House edge

A 50% chance at 1.96× gives an expected return of 98%, a 2% house edge. That is slightly higher than Dice at 49.5%, which pays 2.00× at a 1% edge, so Coin Flip trades a little edge for simplicity.

Base wallets and demo credits

You can play every round as a guest. Sign in with an EVM wallet on Base or BNB Smart Chain (BSC) and each round also earns ROLL points for the leaderboard. Signing in only asks your wallet to sign a message; it never sends a transaction. Ethereum mainnet and Robinhood Chain sign-in are coming soon.

Demo credits only. Credits have no cash value and cannot be bought, deposited, withdrawn or exchanged. Results are server-generated simulations, not a provably fair protocol. See how it works and the FAQ.
