A welcome bonus is the offer a casino gives you when you sign up and make your first deposit. The headline numbers look generous (100%, 200%, sometimes even 500%), but the real value of a welcome bonus depends on the wagering requirement, time limits, game contributions and a few other rules that are rarely shown next to the big number.
This guide explains how deposit match bonuses actually work, how to read the fine print, and how to compare two welcome offers fairly. We focus on mechanics, not marketing, so you can decide whether a bonus is worth claiming for your style of play.
What a welcome bonus is and the most common formats
A welcome bonus is a one-time promotion for new players. It usually triggers on your first deposit, sometimes on your first 2 to 4 deposits. The three most common formats are:
- Match deposit: the casino adds bonus funds equal to a percentage of your deposit, for example 100% of $100 gives you an extra $100 to play with.
- Matched deposit plus free spins: a smaller match, or the same match, combined with a number of free spins on selected slots.
- Tiered welcome package: the bonus is spread over multiple deposits (for example 100% on deposit 1, 50% on deposit 2, 75% on deposit 3), each with its own cap and conditions.
All three formats can be fair or unfair depending on the terms. The format alone does not tell you the value.
How deposit match percentages work
The match percentage tells you how much bonus money you get relative to your deposit, up to a stated cap. A few worked examples:
- 100% match up to $500: deposit $500, receive $500 in bonus, play with $1,000 total.
- 200% match up to $200: deposit $100, receive $200 in bonus, play with $300 total. Deposit more than $100 and you still only get $200 in bonus.
- 50% match up to $1,000: deposit $1,000, receive $500 in bonus, play with $1,500 total.
The cap matters as much as the percentage. A 200% match capped at $50 is a much smaller bonus than a 50% match capped at $500, even though 200% looks larger. Always check both numbers, and never deposit more than you can comfortably lose.
Welcome bonus wagering requirements
Wagering requirements (also called playthrough or rollover) tell you how many times you must bet the bonus before any winnings can be withdrawn. There are two common ways they are calculated:
- Bonus only (B): you must wager the bonus amount a set number of times. Example: 35x on a $100 bonus means $3,500 in total bets.
- Deposit plus bonus (D+B): you must wager the sum of your deposit and bonus. Example: 35x on a $100 deposit plus $100 bonus means $7,000 in total bets, double the work.
Two bonuses with the same headline 35x can therefore have very different real costs. Bonus-only wagering is almost always more player friendly than deposit plus bonus wagering. For most welcome offers, anything under 30x on bonus only is competitive, 30x to 40x is average, and above 50x or any D+B requirement above 40x starts to look heavy.
Time limits for using and clearing a welcome bonus
Welcome bonuses usually expire. There are typically two clocks running:
- Activation window: how long after registration you have to opt in or make the qualifying deposit, often 7 to 30 days.
- Wagering window: how long after the bonus is credited you have to complete the playthrough, commonly 7, 14 or 30 days. Free spins often expire faster, sometimes within 24 hours.
A shorter window with a large wagering requirement forces a high betting pace, which generally favours the casino. If you only play a few hours a week, look for 30 day windows.
Game contribution percentages and clearing faster
Not every game counts equally toward wagering. Typical contribution percentages look like this:
- Slots: usually 100% (some high RTP or jackpot slots are excluded or reduced).
- Table games (blackjack, baccarat, roulette): often 10% to 20%, sometimes 0%.
- Video poker: typically 10% to 20%.
- Live casino: often 10% or excluded entirely.
If you bet $10 on blackjack at 10% contribution, only $1 counts toward the wagering requirement. To clear a welcome bonus efficiently most players use medium variance slots with high RTP that contribute 100%. Always check the excluded games list, because betting on a banned title can void the bonus.
How to compare two welcome bonuses beyond the headline
To compare offers fairly, look past the percentage and check the full picture:
- Match percentage and maximum bonus cap.
- Minimum qualifying deposit.
- Wagering requirement and whether it applies to bonus only or deposit plus bonus.
- Time limit to complete wagering.
- Maximum bet allowed while the bonus is active (often $5).
- Game contributions and excluded titles.
- Maximum cashout (some bonuses cap how much you can withdraw from bonus winnings).
- Country and currency restrictions.
Our bonus comparison tables score these factors together so you see the expected return after wagering, not just the headline match. You can also model a specific offer using our bonus calculator to estimate how much you would need to wager and the realistic value before you opt in.
What happens if you do not meet the wagering requirement in time
If the bonus expires before you complete the playthrough, the casino typically removes the remaining bonus funds and any winnings generated from them. Your original deposit, and any winnings you have already withdrawn from your real money balance, normally stay with you, but rules vary, so always read the specific bonus T&Cs.
This is why it is sensible to either commit to clearing a bonus, or decline it at signup so you can play with your deposit unrestricted. Many casinos let you opt out of the welcome bonus at the cashier.
How Casino Bonus Compare scores welcome bonus real value
We do not rank welcome bonuses by their headline match percentage. Our score combines:
- Effective wagering cost (bonus only vs. deposit plus bonus, multiplier and time limit).
- Game contribution and slot exclusions, which affect how realistically you can clear the offer.
- Maximum bet rules and maximum cashout caps.
- Transparency and fairness of the terms.
- Withdrawal speed and overall operator rating from our review process.
The result is a real value figure shown side by side with the headline number, so a 100% up to $500 offer with low wagering can outscore a 300% up to $1,500 offer with heavy terms. You can read more about our methodology and weights on our ratings page.
Finally, a reminder: bonuses are entertainment, not income. Play within your budget, set deposit and time limits, and only gamble if you are of legal age in your country (18+ in most regions, 21+ in some).
Frequently asked questions
Is a 100% match up to $500 better than a 200% match up to $200?
It depends on how much you plan to deposit. If you deposit $200 or less, the 200% match gives you more bonus money. If you deposit more than about $135, the 100% up to $500 starts to pull ahead and tops out at $500 in bonus funds versus $200. Also compare wagering, time limits and game contributions, because a smaller bonus with friendlier terms often has higher real value.
What wagering requirement is considered good for a welcome bonus?
For bonus-only wagering, anything under 30x is competitive, 30x to 40x is around the market average, and above 50x is heavy. For deposit plus bonus wagering, halve those numbers roughly: under 15x is strong, 15x to 25x is fair, and above 25x is demanding.
Can you withdraw your deposit while a welcome bonus is active?
Usually yes, but withdrawing typically cancels the bonus and any winnings tied to it. Some casinos also require you to wager the deposit a small number of times before any cashout. Always check the cashier and the bonus terms before requesting a withdrawal.
What is a tiered welcome bonus?
A tiered welcome bonus, sometimes called a welcome package, splits the offer across your first 2 to 4 deposits. Each tier has its own match percentage, cap and wagering. You only get the full advertised total if you make every qualifying deposit and clear each stage.
Why do some welcome bonuses include free spins and others do not?
Free spins are a marketing tool to promote specific slots, often new releases from a casino's main game providers. Operators who focus more on table games or live casino sometimes skip spins and offer a larger match instead. Neither format is automatically better, it depends on which games you actually want to play.
