Bonus math
The banner is not the cost
A 100% match sounds simple. The wagering requirement is where the actual commitment lives.
Some terms calculate wagering against the deposit plus bonus, and games may contribute at different rates. Enter the exact clause into a calculator before treating the headline as value.
Long-run math
RTP and the house edge
Per $100 wagered
These are theoretical long-run averages, not a promise about a single session. The lower the RTP, the more the same volume costs over time.
How to use the tools without fooling yourself
A calculator can make the arithmetic visible, but it cannot make an operator safer or a promotion fair. Copy the exact figures from the current terms, save the clause that produced them, and treat any missing number as a question rather than an optimistic default.
