FAQ Bonus Calculator

No , you don't need to log in to use the Bonus Calculator.

Yes, the Bonus Calculator is completely free for all Thunderbolt Casino customers. Use it anytime to calculate how to make the most out of your deposits and bonuses.

A max. coupon amount is the maximum amount of money the casino will add to your deposit when using a deposit bonus. For example, when you use a 100% bonus with a max. coupon amount of R8000, if you deposit R8000, the maximum amount the casino will add to that is R8000. If you deposit R10,000 and use a 100% deposit bonus, the casino will still only add a maximum bonus amount of R8000 to your deposit of R10,000.

Tab 2 "Max. Coupon Amount" allows you to calculate how much you need to deposit to get the maximum amount the casino is willing to offer from a deposit coupon. Tab 2 uses a combination of two values: 1) Max. coupon amount and 2) Deposit bonus %. Please enter these values to make the calculation.

Tab 1 "Amount on Account" allows you to calculate the total amount you'll have on your account using a combination of two values: 1) The amount you wish to deposit and 2) The deposit bonus % offered by the casino. Please enter these values to make the calculation.

No, the Bonus Calculator cannot add any coupons to your account for you. But you can enter a coupon code you wish to redeem, in the area below the calculation summary. The idea is that you use the calculator to advise you on how to maximize the benefits you'll get from a deposit coupon and are then able to enter your desired coupon code from there.

The Bonus Calculator can be found in the right-hand menu in the Thunderbolt casino lobby.
