Casino bonuses can look generous at first glance: extra funds, free spins, or a match on your first deposit. The detail that decides whether a bonus is genuinely useful is usually the wagering requirement.

A wagering requirement tells you how much you need to bet before bonus winnings can be withdrawn. Understanding that number helps you compare offers on their real value rather than their headline amount.

A wagering requirement, sometimes called a playthrough requirement, is a multiplier attached to a casino bonus. It sets the total amount you must stake before you can withdraw money won from that bonus.

For example, imagine you receive a €50 bonus with a 30x wagering requirement. You would need to place €1,500 in qualifying bets before the bonus winnings become eligible for withdrawal:

• Bonus amount: €50
• Wagering requirement: 30x
• Required playthrough: €50 × 30 = €1,500

The multiplier is not a fee. It is a condition that requires you to keep playing until the required turnover is reached.

The most important detail is what the multiplier applies to. Casinos commonly use one of two calculations.

With bonus-only wagering, the multiplier applies only to the promotional funds. A €100 bonus at 30x means €3,000 in qualifying bets.

This is generally the more player-friendly structure because the required turnover is lower.

With deposit-and-bonus wagering, the multiplier applies to both your deposit and the bonus. If you deposit €100 and receive a €100 bonus at 30x, the calculation is:

• Deposit plus bonus: €200
• Wagering requirement: 30x
• Required playthrough: €6,000

The headline multiplier is the same, but the actual amount you need to wager is twice as high. Always check the terms for the wording “bonus only” or “deposit plus bonus.”

Use this simple formula:

Required playthrough = qualifying balance × wagering multiplier

The qualifying balance is either the bonus amount or the combined deposit and bonus, depending on the offer.

Here are three examples:

A lower multiplier is usually better, but it is not the only term that matters. Game contribution, maximum bet limits, expiry dates, and withdrawal caps can all change the practical value of an offer.

Not every casino game contributes equally to wagering. Slots often contribute 100%, while table games and live casino games may contribute less or not at all.

Typical contribution rates look like this:

• Slots: 100%
• Live casino: 10%–20%
• Roulette: 5%–20%
• Blackjack: 0%–10%
• Video poker: 0%–10%

If a game contributes 10%, every €10 wagered only reduces your wagering requirement by €1. That means a 30x bonus can take much longer to clear if you play games with low contribution rates.

Before you claim a bonus, check the eligible games list and contribution table in the casino’s terms and conditions.

A 30x wagering requirement is generally considered reasonable for a standard welcome bonus, especially when it applies to the bonus amount only. It is not automatically a good deal, but it is more achievable than 40x, 50x, or higher requirements.

As a practical guide:

• Under 20x: unusually low and often attractive
• 20x–30x: competitive for many welcome offers
• 30x–40x: common market range
• 40x–50x: high; review the other terms carefully
• Over 50x: often difficult to clear in practice

A lower requirement does not guarantee a better bonus. A €20 bonus at 20x may have less potential value than a €200 bonus at 30x, depending on the game rules and withdrawal cap. Compare the complete offer rather than one number alone.

Many bonuses limit the amount you can stake per spin or hand while completing wagering. A common limit is €5 per bet. Exceeding it can void the bonus and associated winnings, even if you complete the playthrough.

No-deposit bonuses often limit how much you can withdraw after completing the requirement. A €10 bonus might have a €50 maximum withdrawal cap. This is normal, but it should be clear before you start.

Most bonuses have a time limit. You may have seven, 14, or 30 days to complete the wagering requirement. A large requirement paired with a short expiry window can make an offer much harder to use.

Some high-RTP games, jackpot slots, and table games may be excluded from bonus play. If you use a restricted game, your bets may not count toward the requirement or could invalidate the bonus.

A sticky bonus cannot itself be withdrawn; only the winnings generated from it can be withdrawn after wagering. A non-sticky bonus may allow you to withdraw your original deposit if you decide not to continue with the promotion. The terms should explain which structure applies.

When comparing offers, work through this checklist:

1. Check whether the requirement applies to the bonus only or deposit plus bonus.
2. Calculate the total playthrough amount.
3. Review which games contribute at 100%.
4. Confirm the maximum bet allowed during wagering.
5. Check the expiry date and maximum withdrawal cap.
6. Read the rules for forfeiting the bonus if you want to withdraw your deposit.

This takes a few minutes, but it prevents the most common surprise: discovering that a large headline bonus has conditions that make it difficult to use.

Usually, withdrawing or requesting a withdrawal forfeits the active bonus and any winnings tied to it. Some casinos let you cancel the bonus and withdraw your remaining real-money balance. Check the promotion terms before making a deposit.

Often, yes. Winnings from free spins are commonly converted into bonus funds and then subject to a separate wagering requirement. The free spins themselves may be free, but the winnings may not be immediately withdrawable.

If the bonus expires before you complete the requirement, the casino normally removes the bonus and any winnings generated from it. Your original deposit may remain available, depending on the offer’s terms.

They do exist, but they are less common and often have smaller values or lower maximum withdrawal limits. Read the terms carefully to confirm that winnings are genuinely withdrawable without a playthrough condition.

Wagering requirements are not designed to be mysterious. They are a standard part of casino bonus terms, and the maths is simple once you know what to look for.

Focus on the total amount you need to wager, not just the size of the bonus. A transparent offer with a lower multiplier, clear game contributions, and a realistic expiry period is usually more valuable than a larger bonus with restrictive conditions. Always read the full terms before claiming any promotion, and only play within limits that are comfortable for you.
