How to play HEADS OR TAILS

How to play, step by step

1. Choose how many coins to flip: 1, 2 or 3.
2. Pick your call: heads, tails or middle (middle only exists with 2 or 3 coins). With 2-3 coins you can make up to 2 calls with the same stake on each; with 1 coin you make 1.
3. Enter the stake per call and check the limits shown in the game window.
4. Press "Flip". The server draws the result and pays from the table at once.
5. See the latest results, and check any round in the Provably Fair panel of the game page.

Auto mode plays a series for you: set the number of rounds and stop rules for a loss or a win of a set amount. Auto repeats the same calls and stake every round.

Rules

• Heads: every coin flipped lands heads.
• Tails: every coin flipped lands tails.
• Middle: the same flip shows both heads and tails (2 or 3 coins).
• Each coin lands heads or tails with equal chance; each coin comes from 1 bit of an HMAC-SHA256 digest.
• With 2 calls, one flip settles both. Each call has its own stake and payout, so the total can still be below what you staked even when one call wins.

Paytable and RTP

The multiplier is the total you get back, stake included, per unit staked on that call. For example, 1 USDT on heads with 1 coin returns 1.8 USDT on a win.

An RTP of 90% is the theoretical average over a very large number of rounds: players get back 90 of every 100 units staked. The rest is 5% site revenue and a 5% contribution to the Royal Jackpot. Each round is random, so a session can land far above or far below the average.

More likely calls pay less. Middle with 3 coins lands 75% of the time, so it pays 1.2×; heads with 3 coins is much rarer (12.5%), so it pays 7.2×. Every option returns the same average.

Bet limits

Each game shows its per-round bet range in the game window, and the range can change with the site policy, so no fixed figures are printed here. The lowest stake the site allows is 0.01 USDT.

With 2-3 coins and 2 calls, the minimum and maximum apply per call, and the largest possible payout of any outcome must stay within the per-round payout cap.

Royal Jackpot

Every real-money round adds 5% of the stake to the Royal Jackpot and gets a chance at one of its 4 tiers (MINI, MINOR, MAJOR, GRAND). A bigger stake gives a proportionally bigger chance. Demo rounds cannot win the jackpot.

Demo mode vs real money

Demo mode uses free points, not real money, and they cannot be withdrawn. The demo pays more than real play (RTP about 100% versus 90% with real money), so treat it as a way to learn the game, not as a preview of real-money results.

Verify a round yourself

Before you play you see a commitment (SHA-256 hash) of the server seed that decides the results. When you press "Rotate seed", the old server seed is revealed; press "Verify" on the game page and your browser recomputes every round itself. If the hash and the results match, the results were not changed after you played. The full steps are in the fairness guide.

HEADS OR TAILS computes HMAC-SHA256 with the server seed as the key and the message clientSeed:nonce. Coin i lands tails when the lowest bit of byte i is 1 and heads when it is 0.
