Why a bonus is never just free money
A betting bonus is a marketing tool: the bookmaker gives you extra funds or free bets in return for your deposit and your betting activity. The catch is in the conditions. Almost every bonus has a wagering requirement (also called rollover or turnover) that you must satisfy before any winnings can be withdrawn. Understanding those conditions is the difference between a useful offer and an expensive trap.
How wagering requirements work
If you receive a 100 bonus with a 10x requirement on the bonus, you must wager 1,000 before withdrawing. Some offers apply the multiplier to deposit plus bonus: a 100 deposit and 100 bonus at 10x means 2,000 of betting. Over that turnover, the bookmaker margin works against you. At a 5% margin, 1,000 of betting costs about 50 on average, half the bonus value.

The terms that matter
| Term | What to look for | Why it matters |
|---|---|---|
| Wagering multiplier | 5x is gentle, 20x or more is heavy | Sets the cost of unlocking winnings |
| Minimum odds | Often 1.50 to 2.00 | Low-price bets may not count |
| Maximum stake | Often a small cap per bet | Exceeding it can void the bonus |
| Time limit | 7 to 30 days is common | Unfinished bonuses expire |
| Eligible markets | Some exclude certain sports or bets | A bonus on the wrong market does nothing |
| Maximum win | Caps on bonus winnings | Limits what you can withdraw |
| Withdrawal while active | Withdrawing may cancel the bonus | A common way to lose it |
Most disputes involve breaking a rule that was written in the terms: betting above the maximum stake, using an excluded market, or withdrawing too early. Screenshot the terms on the day you accept the offer.
Free bets versus bonus money
A free bet usually returns only the profit, not the stake, so a 10 free bet at 3.00 pays 20 profit if it wins, not 30. Bonus money, on the other hand, may be bet in full but then carries wagering. Free bets with no rollover tend to be better value than larger matched bonuses with heavy multipliers, which sounds counter-intuitive but follows from the arithmetic above.
When a bonus is worth taking
- The multiplier is low (up to about 5x) and applies to the bonus only.
- Minimum odds are modest, so you can bet where you have a view.
- You were going to deposit and bet anyway.
- You have read the maximum stake and time limit and can meet them.
When to skip it
If the offer pushes you to deposit more than your budget, bet on markets you would not otherwise choose, or lock your own money until you have wagered a large sum, skip it. A refused bonus costs nothing; a bonus that traps your balance can cost a lot. Never let a promotion set your stake: use the bankroll rules instead.
A worked comparison
Compare two offers. Offer A is a 50 bonus with a 20x requirement on the bonus: you must bet 1,000 to release it, which costs about 50 at a 5% margin, so the bonus is worth roughly nothing. Offer B is a 20 free bet with no rollover: if you place it at 4.00 it has a 25% chance of winning 60 profit, an expected value of about 15 minus your small chance of variance. Offer B looks smaller but is worth far more. Simple arithmetic such as this is the most reliable defence against marketing language, and it takes less than a minute with the calculator above.
Red flags in bonus offers
Be careful with offers that promise "guaranteed" winnings, require you to share personal documents before a deposit, or arrive through private messages. A legitimate bonus is written in public terms on the operator's own site, and it can be understood without anyone persuading you. If you want to double-check a site, use the legitimacy checklist.
Frequently asked questions
What is a wagering requirement?
The amount you must bet, as a multiple of the bonus (and sometimes the deposit), before winnings can be withdrawn.
Is a 100% deposit bonus worth it?
Only if the multiplier is low and you meet the terms. Calculate the expected cost first.
What happens if I exceed the max stake?
The operator may void the bonus and any winnings from it. Read the cap and stay below it.
Are free bets better than bonus money?
Free bets without rollover are often easier to benefit from, even if the headline figure is smaller.
