You claim a welcome bonus. The headline says £100 free. You win £150. You try to withdraw. Declined. You read the small print and discover you need to wager the bonus amount 40 times before a withdrawal is permitted. You do the maths: 40 × £100 = £4,000 in bets required. The £150 win you thought you had is almost certainly gone by the time you clear it. Sound familiar?

Wagering requirements (also called playthrough requirements) are the single most misunderstood aspect of online casino bonuses. They're not inherently evil. They exist to prevent players from simply withdrawing a bonus the moment it lands. But without understanding exactly how they work, you'll almost certainly come out worse than you would have without the bonus at all. This guide changes that.

What Are Wagering Requirements?

A wagering requirement is a multiplier that tells you how many times you must bet a specified amount before bonus funds (or winnings from free spins) can be withdrawn as cash. The amount that must be wagered is usually the bonus amount, the deposit + bonus combined, or the free spins winnings. Which it is matters enormously.

For example: "35x wagering on bonus" means you must wager your bonus amount 35 times. A £100 bonus at 35x = £3,500 in total bets. "35x wagering on deposit + bonus" means a £100 deposit with a £100 bonus match = £200 × 35 = £7,000 in total bets required. The latter is far more demanding, but both can be presented identically in marketing materials at a glance.

Always check our bonuses page for the full terms on each offer before claiming. We highlight the real wagering figure upfront.

How to Calculate Wagering Requirements

The Maths Behind It

The core formula is straightforward: Total wager required = Bonus amount × Wagering multiplier. But to understand whether a bonus is actually winnable, you need to factor in the house edge. Every casino game has a built-in house advantage. It's the mathematical certainty that over a large enough number of bets, the casino will retain a percentage of all money wagered.

The expected loss while clearing wagering is: Expected loss = Total wager required × House edge %. A 35x wagering requirement on a £100 bonus, cleared on slots with a 4% house edge: £3,500 × 0.04 = £140 expected loss. Statistically, you'll lose more than the bonus was worth before you can withdraw a penny. That doesn't mean you'll always lose. Variance means some players will beat the requirement and walk away with real money. But on average, it's a negative expectation exercise.

Real Example: A £100 Bonus at 35x

Wagering Calculation Example:

Bonus amount: £100
Wagering requirement: 35x bonus
Total wager needed: £100 × 35 = £3,500
Average slot RTP: 96% (house edge: 4%)
Expected loss to clear: £3,500 × 4% = £140

Net expected value: −£40 (you lose £140 in the clearing process, but started with £100 free, so net −£40).

This is the average case. High variance slots mean some players will clear it profitably, others will lose far more. If the same bonus were offered at 20x wagering: £2,000 × 4% = £80 expected loss, meaning the bonus has a positive expected value of +£20.

The takeaway: a lower wagering requirement isn't just "slightly better." It can flip a mathematically negative bonus into a mathematically positive one.

Which Games Count Towards Wagering?

Here's where most players get caught out. Not all bets count equally towards clearing your wagering requirement. Casinos assign contribution percentages to each game type, and table games and live casino often contribute a fraction of what slots do, or nothing at all.

Slots (usually 100%)

Slot games almost universally contribute 100% towards wagering requirements. A £10 slot bet counts as £10 of wagering completed. This is why strategies for clearing wagering focus on slots. There are exceptions, though. Some casinos exclude specific high-RTP slots (those above 96.5% or 97% RTP) from bonus wagering, or cap them at a lower contribution rate. Always check the excluded games list, which reputable casinos are required to publish in their bonus terms.

Table Games (usually 10–20%)

Blackjack, roulette, baccarat, and other table games typically contribute between 10% and 20% of each bet towards wagering. Occasionally 0%. The reason is straightforward: skilled play at blackjack (using basic strategy) reduces the house edge to around 0.5%, making it extremely effective for clearing wagering requirements. Casinos protect themselves by either heavily restricting table game contributions or excluding them entirely under bonus terms.

If you're specifically trying to clear a wagering requirement efficiently, table games are almost never the right choice unless the contribution rate is at least 50%.

Live Casino (usually 0–10%)

Live dealer games (Evolution Gaming's blackjack, roulette, baccarat, and game show titles) typically contribute 0% to 10% towards wagering requirements. Again, this reflects the lower house edge achievable with optimal play. Some casinos exclude live casino entirely from bonus wagering. Assume 0% unless the T&Cs explicitly state otherwise.

5 Proven Strategies to Clear Wagering Requirements

1. Stick to High-RTP Slots

If you're going to clear wagering on slots, use the highest-RTP slots the casino permits under its bonus terms. The difference between a 94% RTP slot and a 97% RTP slot sounds small, but over £3,500 in wagering it's significant: 94% RTP = 6% house edge = £210 expected loss. 97% RTP = 3% house edge = £105 expected loss. That's £105 in expected value just from choosing the right game. Popular high-RTP slots to look for: Blood Suckers (NetEnt, 98% RTP), Monopoly Big Event (WMS, 99% RTP), Rainbow Riches (Barcrest, 95–98% depending on variant). Always verify the specific RTP for the version available at your casino, as it can differ from the published "top" figure.

2. Avoid Table Games Unless You Have To

If you're a blackjack player, being forced onto slots feels wrong. We get it. But under standard bonus terms, a £10 blackjack bet contributing 10% is worth only £1 of wagering progress. You'd need to bet £35,000 at the blackjack table to clear the same requirement a slots player clears with £3,500. Unless the table game contribution is explicitly listed as 50% or higher, play slots during the clearing phase and return to your preferred games once you've withdrawn.

3. Set a Loss Limit Before You Start

Before you place a single bet with bonus funds, decide the maximum you're willing to lose in the clearing attempt. Not the theoretical maximum. The actual number you've decided you're comfortable with. Use the casino's deposit limit or loss limit tool to enforce it. If you hit your limit, stop. The bonus was free money. Losing an amount you could afford was the price of the lottery ticket. Do not chase.

4. Choose Casinos with Lower Wagering (Spela has 0x!)

The most effective strategy is avoiding high-wagering bonuses entirely. Several casinos now offer 0x wagering. Spela Casino is the most notable example, where free spins winnings are credited as real cash with no wagering at all. Other operators offer 20x wagering rather than the industry-standard 35x, which as we've shown above makes a substantial mathematical difference.

Our bonuses page ranks offers by wagering-adjusted value, not headline bonus size. The best low-wagering offers are also highlighted on our WinAMPM Specials page, where we've negotiated exclusive terms directly with operators.

5. Read the Full T&Cs Before Claiming

This sounds basic. It is basic. And yet the number of players who claim a bonus without reading the terms is extraordinary. Before claiming any casino bonus, check: What amount is the wagering applied to, bonus only or deposit + bonus? What is the game contribution rate for the games you actually play? Are any high-RTP slots excluded? Is there a maximum bet limit while bonus is active (usually £5 per spin)? Is there a time limit to clear the wagering? What is the maximum withdrawal from bonus winnings? Each of these terms can dramatically change the actual value of the offer.

"I spent years claiming big bonuses and wondering why I never seemed to withdraw anything. Then I started actually reading the T&Cs and doing the maths. Now I only claim bonuses where the numbers make sense, and my withdrawal rate has improved dramatically."

When It's Not Worth Claiming a Bonus

Sometimes the honest answer is: don't claim the bonus. Specifically, consider skipping the bonus if:

  • The wagering requirement is above 50x. The expected loss to clear almost certainly exceeds the bonus value.
  • Your preferred games (table games, live casino) contribute less than 25% and you're not willing to play slots instead.
  • The bonus has a very short time limit (e.g., 3 days) that would require uncomfortably large session volume to clear.
  • The maximum withdrawal from bonus winnings is capped at a low amount (e.g., 5x the bonus value). Your potential upside is severely limited.
  • You're in a period of financial stress or chasing previous losses. No bonus is worth amplifying that.

Playing without a bonus means every win is immediately withdrawable. For players who like to cash out frequently, this "bonus-free" approach often makes more financial sense than tying up funds in a clearing cycle.

The Bottom Line

Wagering requirements are manageable once you understand the maths. Calculate the real cost of clearing before you claim anything. Always check which games contribute and at what rate. Use high-RTP slots when clearing is unavoidable. Set a loss limit before you start. And wherever possible, prioritise casinos offering 0x or low-wagering bonuses.

The best bonus isn't the one with the biggest headline figure. It's the one where the net expected value is highest after wagering is factored in. Our bonuses page does that maths for you so you don't have to.
