Crypto casinos' original games — Dice, Limbo, Crash, Plinko, Mines — have simple rules and are usually provably fair: every result can be checked after the game. That is a real advantage over games whose fairness you have to take on trust.
But "verifiably fair" does not mean "good for the player". The house edge is built into the game's rules, and provably fair proves only that those rules were followed. In this post we calculate what that edge means in money. All the numbers below are examples: a specific game's house edge or RTP is stated in the game info and can differ from casino to casino.
The house edge is a percentage of turnover, not of the deposit
If a game's RTP is 99%, the house edge is 1%. That does not mean you lose 1% of your deposit. It means that in the long run you lose on average 1% of all your bets combined — that is, of turnover.
Example: you deposit 100 euros and play with 1-euro bets. If you make 1,000 bets, turnover is 1,000 euros and the expected loss is 1% of that, 10 euros. If you make 10,000 bets, turnover is 10,000 euros and the expected loss is 100 euros — the whole deposit. The same money "cycles" through the game several times and every cycle costs the edge. Background: expected value on Wikipedia.
How Dice builds the edge into the payout
In Dice you choose the win chance and the game calculates the multiplier. A typical formula is:
multiplier = (100 − house edge) / win chance in per cent
With a 1% edge and a 49.5% win chance the multiplier is 99 / 49.5 = 2.00×. Without an edge the fair multiplier for the same chance would be 100 / 49.5 ≈ 2.02×. The difference is small, but it is in every bet. The same logic applies in Limbo: if you target a multiplier x, the win chance with a 1% edge is about 99 / x per cent. In Crash the edge is hidden in the distribution of multipliers in the same way.
The most important conclusion: no combination of probability and multiplier changes the edge. A small win chance and a big multiplier, or a big chance and a small multiplier — the expected loss per unit of turnover is the same. Only how much the result swings changes.
Speed: the hidden price of an original game
Original games are fast and many have autobet. This is exactly where a small edge becomes a large sum:
| Bet | Bets per hour | Turnover per hour | Expected loss at 1% edge | Expected loss at 3% edge |
|---|---|---|---|---|
| €1 | 100 | €100 | €1 | €3 |
| €1 | 600 | €600 | €6 | €18 |
| €1 | 3,000 | €3,000 | €30 | €90 |
The table is simple multiplication: turnover × edge. But it shows why an hour played by hand and an hour on autobet are completely different things, even with the same stake. You can calculate it yourself with the house edge calculator or the RTP calculator.
Volatility: why the result differs from the expected one
The expected loss is an average. A single session can be far from it — in either direction. The smaller the win chance, the greater the volatility.
An example from Limbo: if you target a 100× multiplier with a 1% edge, the win chance is about 0.99% per bet. On average a win comes about every 101 bets. But the probability of no win at all in 200 bets is (1 − 0.0099)^200 ≈ 14%. So roughly one in seven 200-bet sessions ends without a single hit. That is neither a fault nor a cheat — it is probability. And it is why "it has to come now" is the gambler's fallacy.
In Plinko and Mines you choose a risk level or the number of mines. That changes the distribution of results and therefore the volatility; whether it also changes the edge is stated in the game info. Always look at the game's own RTP, not a general claim.
Bonuses and original games
If you play with a bonus, the wagering requirement multiplies turnover. A 30× requirement on a 100-euro bonus means 3,000 euros of turnover; at a 1% edge the expected cost is 30 euros, at 3% 90 euros. Many casinos, however, limit the game contribution or exclude original games from bonus play altogether. Calculate first: the wagering calculator and the guide how wagering really works.
What to take away
- Compare games by RTP and read it in the game info.
- Think of expected loss per hour, not per bet: turnover × edge.
- Avoid autobet or set a firm stop limit on it.
- No system — Martingale or "signals" — changes the edge. See also crypto scams targeting casino players.
If play has turned into chasing losses, take the self-test and if needed call 15410.
Frequently asked questions
Are low-probability bets more profitable for the casino?
No, if the edge is the same. The expected loss per unit of turnover does not depend on which probability and multiplier you choose. What changes is volatility: a low probability means longer losing streaks and rarer big wins.
Is autobet dangerous?
It does not change the edge, but it multiplies turnover per hour. The same stake therefore brings a several times larger expected loss. If you use it, always set a stop limit for both loss and win.
Where do I find a game's real RTP?
In the game info or rules at the casino. In original games it is often stated in the game window itself. If the RTP is not shown anywhere, that is itself a piece of information.
