Flip a coin on play money
Heads or tails — a clean 50/50 at 1.96×.Theoretical return 98% · up to 1.96×
Coinflip in short
Heads or tails is the simplest game a casino can offer: pick a side, flip, your side came up or it did not. The chance is exactly 50% and no animation, bonus feature or paytable hides it.
Which makes it the best place to show the house edge. In every other game the edge has to be calculated. Here it takes comparing two numbers: the coin lands your way half the time, but the win is not double — it is 1.96 times.
The entire economics of a casino lives in that four percent.
How a round works
- Pick a side. Heads or tails.
- Place the bet.
- The flip. The coin lands. If it is your side, you get your stake times 1.96.
The fair price and the actual price
| A fair game | This demo | |
|---|---|---|
| Win chance | 50% | 50% |
| Payout | 2.00× | 1.96× |
| Win on a €10 stake | €20 | €19.60 |
| Return | 100% | 98% |
| House edge | 0% | 2% |
A fair game is two players flipping between themselves — one puts up ten, the other puts up ten, the winner takes twenty. That game has no house edge and its long-run result is zero.
Casinos do not offer that game. A casino pays 1.96× and keeps four cents of every euro paid out in wins. That is the entire business model — no cheating, no weighted coin. Just slightly less than the fair price.
What 2% means over time
Two percent sounds like nothing. Here is what happens staking ten euros a flip:
| Flips | Total staked | Expected result |
|---|---|---|
| 10 | €100 | −€2 |
| 100 | €1,000 | −€20 |
| 1,000 | €10,000 | −€200 |
| 10,000 | €100,000 | −€2,000 |
Note the middle column. A thousand ten-euro flips is ten thousand euros staked, not lost — the same money circulates, wins go back in. That is exactly why the long-run loss is so much larger than a player judges from their bankroll.
This is not a forecast for your evening. A hundred flips can easily end up ahead — the chance is half, after all. But the more flips, the more firmly the result settles toward 98%.
Why there are no strategies here
- Previous flips say nothing. Five heads in a row does not change the next flip. This is the gambler's fallacy at its purest — and a coin is the easiest place to check it for yourself.
- Doubling does not help. Martingale turns many small losses into one large one. The expected result stays at −2%.
- The side you pick is irrelevant. Heads and tails are the same game.
Where 2% sits next to other games
| Game | House edge | Return |
|---|---|---|
| Blackjack with basic strategy | ~0.5% | 99.5% |
| Dice, crash, limbo | 1% | 99% |
| Roulette (European) | 2.7% | 97.3% |
| Coinflip (this demo) | 2% | 98% |
| Slots (typical) | 3–6% | 94–97% |
So a coinflip is a middling game — better than a typical slot, worse than blackjack. And unlike blackjack, there is no decision available to improve it.
