How does the wagering calculator work?
The wagering calculator uses three steps, and you can follow each with the figures above:
- Bets needed = amount the requirement applies to x the multiple / the share of each bet that counts.
- Average cost = bets needed x house edge.
- Average value = bonus less average cost.
What house edge should you enter?
Use the edge of the game you plan to play. These figures come from our games pages, and they assume best or near-best play where skill applies. Check the rules of your exact game.
| Game | House edge |
|---|---|
| Blackjack, Atlantic City rules | 0.43% |
| Baccarat, banker bet | 1.06% |
| Roulette, single zero | 2.70% |
| Roulette, double zero | 5.26% |
| Slots | 2% to 15%, varying by machine |
What does "game counts at" mean?
"Game counts at" is the share of each bet that counts toward the wagering requirement. If a game counts at 50%, a $10 bet clears only $5, so you must bet twice as much. Michigan requires offers to set out requirements and limits by game type. Find the rate in your offer's terms, and leave it at 100% if every bet counts in full.
What does a negative bonus value mean?
A negative bonus value means the average cost of clearing the bonus is more than the bonus itself. A $50 bonus at 30x needs $1,500 in bets, which costs an average of $75 at a 5% edge, leaving a value of -$25. You may still win in one session, but on average the requirement costs more than the bonus gives. See wagering requirements.
What does the calculator leave out?
The calculator covers only the bets and their average cost. It does not include these terms, which can reduce a bonus further:
- The expiry date, which may give you too little time.
- Any maximum bet or maximum win.
- Rules on which games you may play at all.
- The chance of losing your balance before you finish.
What are the rules in your state?
Each state sets its own online casino rules. Pick a state to see its status, its regulator and the date we last checked it.
