Quick answer: the best casino bonus is not the biggest one, it is the one you can realistically turn into cash. For most players that means low wagering, a sensible max bet and no tiny winnings cap.

How we review casino bonuses
- We read the full terms: wagering, whether it applies to the bonus or deposit plus bonus, max bet, winnings caps, excluded games and time limits.
- We cross-check the details: we compare the terms with the casino’s own pages and other independent review sites, and give a range when sources disagree.
- We test payouts where we can: our own withdrawal tests are in our 1win, iWild and FortuneJack reviews. Where we have not tested a casino, we say so.
How wagering requirements work
The wagering requirement (or rollover) is how many times you must bet the bonus before you can withdraw it. It matters more than the headline percentage. Use our wagering requirement calculator to see what any bonus is really worth.
| Example: $100 deposit + $100 bonus | You must bet |
|---|---|
| 35x the bonus | $3,500 in total bets |
| 35x deposit + bonus | $7,000 in total bets |
| 10x the bonus | $1,000 in total bets |
Also check game contributions. Slots usually count 100% towards wagering, while table and live games often count far less or not at all. Our welcome bonus guide explains every term in plain English.
Types of casino bonuses
Welcome packages
A match on your first deposit, often spread over the first three or four deposits. For example, 1win’s 500% package is split 200%, 150%, 100% and 50%.
Free spins
Spins on a set slot, usually bundled with a deposit match. Winnings are normally paid as bonus money with their own wagering and often a cap.
Cashback
A percentage of your net losses paid back daily or weekly. Some cashback is wager-free; some carries low wagering, such as Immerion’s 3x. Cashback softens losses but does not make gambling profitable.
No-deposit bonuses
Small offers, usually free spins, for signing up without depositing. They come with strict caps; see our crypto casino no deposit bonus guide.
How our casino bonus wheel works
The Wheel of Bonus Destiny at the top of this page is a quick way to choose a welcome bonus when several look good. Press Spin and the wheel stops on one casino at random. Each casino’s chance matches the size of its slice: 1win has a bigger slice because it is our top-rated casino (about a 24% chance), and the other five casinos have equal slices (about 15% each).
Spinning our wheel doesn’t win you anything by itself. It shows you a real welcome offer from the comparison table below, and you still need to sign up and make a deposit to claim it. Spin as often as you like.
Spin the wheel promotions at online casinos
Some casinos also run their own bonus wheels, often called daily wheels, fortune wheels or prize wheels. You usually get a spin each day or after a deposit, and prizes can include free spins, bonus money or loyalty points. Before you spin a casino’s wheel, check:
- Wagering on prizes: bonus money and free spin winnings from a wheel usually have to be wagered before you can withdraw them.
- Deposit rules: some wheels only unlock after a qualifying deposit.
- Expiry and caps: prizes often expire within days, and free spin winnings may be capped.
A casino bonus wheel isn’t the same as a slot with a bonus wheel feature. That is a bonus round inside a slot game; see our types of slots guide.
Casino bonus FAQs
Is the bonus wheel random?
Yes. Each spin is decided at random in your browser, and each casino’s chance equals its share of the wheel: about 24% for 1win and about 15% for each of the other five casinos.
What is a sticky casino bonus?
A sticky (non-cashable) bonus lets you bet with the bonus funds, but the bonus itself is removed when you withdraw. Only the winnings above it can be cashed out.
Can I claim a casino bonus with crypto?
Yes, at most crypto casinos. Some offer different bonuses for crypto deposits, so check the cashier for your coin.
Is a 40x wagering requirement worth it?
It is high. On average you will lose part of the bonus to the house edge while you wager, so a lower requirement such as 10x is usually better value. Check any offer with our bonus value calculator. Treat any bonus as extra playtime, not a way to make money.
Do I have to take a bonus?
No. You can usually decline it and play with your own money, with no wagering on withdrawals beyond the casino’s normal rules.
Important: check your local laws before you play
Online gambling laws differ from country to country, and in some places it is restricted or not permitted at all. Check that online gambling is legal where you live and that the casino accepts players from your country. You must be 18 or older (or the legal gambling age in your country, if higher). Only gamble with money you can afford to lose.
