Coin Flip game: odds of one call, RTP and what a run of calls pays
Heads or tails, with a stake on the call. A right call pays a little under double, and that small gap is how the game earns. Many titles also let you keep calling to build a larger multiplier.
How to play Coin Flip
- Set the stake and call a side: heads or tails.
- The coin is flipped. Each of the 2 sides has a chance of 50%.
- A right call pays the multiplier shown. A wrong call takes the stake.
- In titles with a series mode you may flip again after a win. Each right call multiplies the payout, and one wrong call ends the series with nothing.
Coin Flip odds: one call and a run of calls
One call wins 50% of the time. A run of right calls halves the chance with every flip. The multipliers in the table are what an RTP of 97.0% implies, as an example. They are not the pay table of a specific title. A single flip is a dice bet at a win chance of 50%, so the dice calculator gives its numbers for any RTP.
| Right calls in a row | Chance | Multiplier at 97.0% |
|---|---|---|
| 1 | 50.0% | 1.94x |
| 2 | 25.0% | 3.88x |
| 3 | 12.5% | 7.76x |
| 5 | 3.13% | 31.04x |
| 10 | 0.0977% | 993.28x |
A fair coin with no house edge would pay 2.00x on one call. At 97.0% it pays 1.94x. 3 right calls in a row happen 12.5% of the time, and 10 in a row about once in 1,024 series.
Single flip or series in Coin Flip: what changes
A single flip keeps results close together: half of the calls win, and a win nearly doubles the stake. A series trades that for a rare large payout. The cost does not fall or rise with the length of the series, as long as the title applies one RTP to every mode. It is 3 per 100 staked at 97.0%. Losing runs still happen at even odds. Several wrong calls in a row are ordinary, and the losing streak calculator shows how likely each length is. Doubling the stake after every loss is a plan often tried on even bets. It fails for the reason given in does Martingale work on crash games?: the stake grows faster than any balance or bet limit allows. The expected loss calculator gives the cost of a session at flat stakes.

Is online Coin Flip fair? Checking a flip
A fair flip means both sides are equally likely and the result is fixed before you see it. The payout below 2.00x is the price of the game and is not a sign of a bent coin.
In a provably fair title the side is derived from a server seed, a client seed and a nonce, and a finished flip can be rebuilt in the provably fair verifier. The game is close to Dice set at a win chance of 50%, where the same kind of check applies. Titles without seeds state their RTP in the rules and offer no check of a single flip.
