How to Use the Casino Offer Simulator
Our casino offer simulator plays through a casino bonus thousands of times using random results, just like the real game would. It then shows you the average outcome, how often you would lose everything and how long it takes. As a result, you get a far better idea of what an offer is worth than the headline bonus amount.
1. Choose the bonus type
Pick Standard for most welcome offers, where your deposit and bonus are added together and you can withdraw what is left once wagering is complete. Alternatively, choose Sticky if the terms say the bonus itself can never be withdrawn. Post-wager is for offers where you wager your deposit first and the bonus is then paid as cash.
2. Enter the deposit, bonus and wagering
Type in your deposit and the bonus amount in pounds. Next, enter the wagering multiplier from the terms, such as 10×, and say whether it applies to the bonus only or to the bonus and deposit. The simulator then shows the total amount you will need to wager. If the offer limits how much you can withdraw, add that figure in Max withdrawal too.
3. Choose how you will play
Select the game you plan to use. For slots, pick the volatility and enter the game’s return to player (RTP), which you can usually find in the game’s information screen. For table games, on the other hand, the RTP is filled in for you. After that, enter your stake per bet and roughly how many seconds each bet takes.
4. Run the simulation
Finally, choose 1,000, 5,000 or 10,000 simulations and press Run simulation. More simulations take slightly longer, but they also give more stable results.
Understanding Your Results
- Estimated value is the average profit or loss across every simulated attempt, after taking away your deposit. A positive number means the offer is worth taking on average.
- Chance of profit shows how often you finish with more money than you deposited.
- Bust rate is how often your balance runs out before the wagering is complete. With a high bust rate, you will usually lose your deposit, although you will occasionally win big.
- Average time tells you how long the wagering takes, based on your seconds per bet.
- Value per hour divides the estimated value by the average time. In this way, you can compare offers that take different amounts of time.
- Spread of results plots every outcome as a chart, with red bars for losses and green bars for profits.
Remember that the estimated value is an average over many attempts. On any single attempt, therefore, you could do much better or much worse.
Tips for Getting the Most From the Simulator
- Check which games are allowed. Many bonuses exclude table games or count them at a lower rate towards wagering, so only simulate games the terms allow.
- Try different volatilities. Low volatility slots give steadier results and a lower bust rate. By contrast, high volatility slots bust more often but can produce big wins.
- Respect the maximum bet. Most bonuses cap the stake you can use while wagering, often at £5 or less. Breaking this rule can void your winnings.
- Compare offers fairly. Use the same game and stake when comparing two offers. Then look at value per hour as well as estimated value.
Casino Offer Simulator FAQs
How accurate is the casino offer simulator?
It is as accurate as the figures you enter. With the correct RTP, stake and terms, the average of thousands of runs is a reliable guide. Even so, your own single attempt can still land anywhere in the spread.
Why does a bonus with a high bust rate still show positive value?
Because the rare big wins can outweigh the frequent small losses. In other words, the offer pays off on average but not every time.
Does the simulator store my data?
No. Everything runs in your browser, and nothing is sent to us or to any casino.
