Bottom line: If you’ve ever seen a casino offer a “40x playthrough” or “40x wagering requirement” on a $200 bonus and wondered what that really means, you’re not alone. Sound too good to be true? It probably is if you don’t know the fine print. I’ve been playing online casinos for over a decade — both offshore and regulated Canadian platforms — and I’m here to break down the jargon, explain the math, and warn you about common pitfalls.
Ever Wonder Why They Offer So Much?
Casinos like Bet365, PlayNow, and BCLC often promote flashy bonuses — think “100% deposit match up to $100” or even higher. On the surface, it sounds like free money. But so, what’s the catch?
The catch is the wagering requirement, sometimes called the playthrough requirement. It’s the number of times you must bet the bonus amount (and sometimes the deposit too) before you can withdraw any winnings. That’s where the 40x comes in.
What Is a 40x Wagering Requirement?
In simple terms, a 40x wagering requirement means you must wager 40 times the bonus amount before cashing out. If you have a $200 bonus, here’s how to calculate what that means in real betting dollars:
Bonus Amount Wagering Requirement Total Amount to Bet $200 40x $200 × 40 = $8,000So, you need to place bets totaling $8,000 before you can withdraw any winnings from that $200 bonus. That’s a pretty hefty commitment.
How Much Is $8,000 in Real Bets?
To put it in perspective, if you’re betting $20 per spin, you’d need to spin:

- $8,000 ÷ $20 = 400 spins
That’s a lot of playing time, and it doesn’t guarantee you’ll come out ahead — it just means you’re eligible to withdraw your bonus winnings once you’ve met these terms.
Deposit Match Bonus Example: 100% Match Up to $100
Let’s say you deposit $100 using a payment method like Interac or iDebit. The casino offers a 100% deposit match bonus up to $100. This means:
- You deposit $100 The casino adds $100 bonus Total bankroll = $200
With a 40x wagering requirement on the bonus, you need to wager 40 × $100 = $4,000 before withdrawing. But be aware that some casinos apply wagering to the deposit + bonus (so 40 × $200 = $8,000), which doubles the playthrough.
Game Contribution Percentages Matter
Here’s a big one people often overlook. Not all games count 100% toward meeting the wagering requirements. For example: ...where was I going with this?
- Slots usually contribute 100% Blackjack and table games might contribute 10% or less Video poker can be zero or very low
So if you play blackjack on a 40x wagering bonus, and blackjack contributes only 10%, you’d effectively need to wager 10× more to clear the bonus.
Example: If you need to wager $8,000 for the bonus and blackjack contributes 10%, the effective wagering becomes:
- $8,000 ÷ 0.10 = $80,000 in blackjack bets
That’s a dealbreaker for many. Always check the “game contribution” rules in the bonus terms.
Regulated Canadian Casinos vs. Offshore Platforms
The regulated Ontario market, which includes sites like PlayNow and BCLC, operates under strict rules designed to protect players:
- Clear, transparent bonus terms Limits on wagering requirements Fair game contribution rules Reliable payment methods like Interac and iDebit
Offshore sites like Bet365 often have more aggressive bonuses but also more complex or restrictive terms. You might see a huge bonus number, but the wagering requirements and contribution percentages make it practically impossible to cash out.

Don’t Chase the Biggest Bonus Number
Here’s where many players get tripped up: they see a “C$5000 bonus” and think they’ve hit the jackpot. But if the wagering requirement is 40x, that means:
- 40 × $5,000 = $200,000 in bets
Do you have the bankroll and time to wager $200,000? Probably not. That’s why I keep a spreadsheet tracking the real cost of bonuses — not just the headline numbers.
Sound too good to be true? It usually is. Focus on reasonable bonuses with clear terms and manageable wagering.
Watch Bonus Expiration Dates and Win Limits
Bonuses don’t last forever. Many come with expiration dates — typically 7, 14, or 30 days. If you don’t meet the wagering requirements in time, you lose the bonus and any winnings derived from it.
Some casinos also cap the maximum amount you can win from a bonus. For example, you might only be able to withdraw up to $500 of your bonus winnings, even if you hit big.
Always check for:
- Bonus expiration date Maximum cashout/win limit Game restrictions
Summary: How to Calculate and Approach a 40x Playthrough
Identify the bonus amount (e.g., $200) Multiply by the wagering requirement (e.g., 40 × $200 = $8,000) Check if the deposit amount also counts toward wagering Factor in game contribution percentages (slots vs. table games) Note the bonus expiration and max win limits Choose trusted casinos with clear terms — regulated platforms like PlayNow and BCLC are safer betsFinal Thoughts
Understanding wagering requirements like the 40x playthrough helps you avoid costly mistakes and frustration. Casinos want you to play, not just grab free money. So, always read the fine print, do the math, and don’t get dazzled by huge bonus numbers without considering the real betting commitment behind them.
Stick with regulated Canadian casinos that support reliable payment methods like Interac and iDebit. They may offer smaller bonuses, but the terms are fairer and your money is safer.
Remember: a $200 bonus with a 40x wagering requirement means you need to bet $8,000 before cashing out. If you’re not ready for that, look for bonuses with lower wagering or no wagering requirements at all.
Play smart, stay safe, and don’t let how to find low wagering casinos flashy offers blind you from the real deal.
