Wagering Requirements Explained: The Real Math Behind Casino Bonuses

What Wagering Requirements Actually Are

Wagering requirements, also known as rollover or playthrough requirements, are the bets you must place to be allowed to cash out your winnings from a bonus.

Requirements are represented as a multiplier (e.g., 20x, 35x, 50x). This expresses how many times a player must wager the bonus, or the bonus plus the deposit.

Most users are aware that the house always wins and the bonus is not truly free money; however, the terms and conditions put in place allow the house to recover the bonus in the long run.

Why Casinos Use Them

Casinos don't need to tie bonus money to wagering requirements. However, they do this for two reasons.

1. Stopping Money Laundering and Bonus Abuse

Making sure that money isn't being laundered via casinos is a concern across countries, and the agency that combats money laundering in Canada is FINTRAC.

One reason casinos implement wagering requirements is to prevent money laundering. If wagering requirements are in place, it is much harder for a customer to use the casino to process illegitimate financial transactions.

2. Business Viability

Bonus wagering requirements also exist for the sake of the casino's survival. Without them, a casino would eventually go bankrupt as players would deposit money, withdraw the money along with a free bonus, and then repeat the process. Likewise, wagering requirements give the casino a reasonable expectation of winning in the long run.

The Math: How to Calculate Real Bonus Value

House edge is inherent in all casino games, even with bonuses. Expected value of a casino bonus estimates what the bonus is truly worth, accounting for the house edge.

The Formula

This is just an estimate, and an imperfect one at that. We’re going to assume you wager the bonus 100% with bets that count the full amount and that you wager the full requirement. In the long run, casinos expect to win, and bonus offers reflect this. Let’s take a look at an example.

So What's Actually Fair?

We ran the numbers for slots at 96% RTP. Here's where they fell:

Our policy is to flag requirements greater than 25x and to flag anything greater than 40x in red; only bonuses at 40x or less go on our low wagering list. Bonuses with wagering requirements greater than 25x are only listed if there are other more favorable terms, such as no maximum cash-out.

Bonus-Only vs. Bonus+Deposit Wagering

This detail is easy to miss, and it can double the amount you have to bet. Casinos calculate wagering in one of two ways:

Type 1: Bonus-Only Wagering (Better)

For wagering requirements, only the bonus amount counts.

Type 2: Bonus Plus Deposit Wagering (Worse)

The same is true for your deposit.

While a bonus may have a 20x wagering requirement, the total amount you are required to bet may be 40x.

Game Weighting: Why Your Choice of Game Matters

Not every dollar counts. Casinos vary contribution rates by game. While slots may count 100% towards requirement, table games like Blackjack and Roulette may count only 10-20%. Some may count nothing at all.

This difference is because, for example, Blackjack and video poker have a low house edge. As a result, skilled players can take advantage of the house and potentially clear the wagering requirement. To offset this risk, slots are weighted 100% and games with a low house edge are restricted or excluded, altogether.

What This Means for Your Wagering Math

To clear a $2,000 requirement by betting on Blackjack, where the contribution is set at 10%, you would have to place bets totaling $20,000.

Generally speaking, wagering requirements can be met fastest by betting on slot machines. As seen in equation 3, the assumption is that slot machines are counted at 100%. For other machines or table games, that requirement would have to be divided by that game’s contribution rate, and the edge of that game would have to be evaluated. For a game with a low contribution rate, say 10%, the requirements would have to be met 10 times over, making slot machines the game of choice for wagering requirements.

Why Most Players Never Complete Wagering

At 30x or more wagering requirements, the house edge inevitably catches up to the player, and most will go broke before reaching the requirement. Skill has nothing to do with the outcome of these games.

1. The Balance Just... Disappears

Most players don’t complete wagering requirements. That doesn’t mean they are bad at the games. It is luck based, and the casino has a house edge. The house edge will get you in the long run, and most players go broke along the way. It isn’t bad luck. It is design.

2. Time Limits Are Brutal

In addition, some bonuses expire in 7-14 days. So, a player has a limited time period to complete a high wagering requirement. A $100 bonus with 30x wagering requirement becomes $3,000 in bets, which means the player has to bet $214 every day for 14 days.

3. One Wrong Bet Kills Everything

Players are restricted even further with rules regarding max bets. These restrictions are usually around $5 to $8 a spin. Accidentally placing one spin over that limit can result in the bonus and all winnings being forfeited.

4. Game Restrictions Are a Minefield

While a bonus is active, some games are excluded from helping the player to complete the wagering requirements. A player can even lose a bonus, and all winnings from it, with a single spin on an excluded game.

How to Spot Fair vs. Predatory Requirements

Not all bonuses are designed to take money from players. In our interest, we must be able to recognize which bonuses have fair requirements and which do not.

Wagering Numbers That Work in Your Favour

• ✓ 25x or less, and calculated on the bonus only (not bonus plus deposit)
• ✓ Expected value is positive or break-even when you run the formula from Section 3
• ✓ At least 30 days to complete the playthrough
• ✓ Slots count at 100%, and there's a reasonable selection of allowed games

Wagering Numbers That Should Make You Walk

• ✗ Above 40x, especially when applied to bonus plus deposit
• ✗ 7 days or less to clear it. Run the daily math from Section 6 and you'll see how unrealistic that is.
• ✗ Expected value is deeply negative. If the formula gives negative $40 or worse, you should expect to lose money just by playing through it.
• ✗ You mainly play table games, and they count 10% or less or are excluded

Other Red Flags in the Terms

• ✗ Separate wagering on free spin winnings, on top of the main bonus
• ✗ Very low maximum win or cashout caps
• ✗ Unusually low max bet limits
• ✗ Sticky bonuses, where the bonus itself can never be withdrawn
• ✗ Long lists of excluded games that leave few ways to clear the bonus
• ✗ Wagering requirements on loyalty or comp point rewards

The Strategic Approach: When to Claim & When to Walk

Here's how we think about it at CasinoEnjoyer:

When It Makes Sense to Claim:

• Wagering is 25x or less (ideally under 20x) and it's calculated on the bonus only
• You have enough time to play through it before the deadline without rushing
• You've run the math and the expected value is positive or break-even
• There's no cashout cap, or the cap is at least 10x the bonus
• You've actually read the full T&Cs and know what you're signing up for

When You're Better Off Skipping It:

• Wagering is above 25x and you're hoping to profit: past that point, the expected value on a typical slot is negative
• The deadline is too tight for your schedule
• The terms are confusing or seem to contradict themselves
• The games you actually want to play count 10% or less, or are excluded
• It's a tiny bonus ($10 or $20) with heavy strings attached. It's rarely worth the hassle.

Bankroll Management for Bonus Clearing

Decided to go for it? Here's a game plan that actually works:

1. Determine how much you need to wager overall. Example: $100 in bonus cash at 25 times wager means $2,500.
2. Break it down by day. With 14 days to clear it, that's about $180 in bets per day.
3. Set a daily loss limit. Decide before you start how much of your own money you're willing to lose in a day, for example $50, and stop when you hit it.
4. Play low or medium volatility slots. High volatility slots can drain your balance fast. Save them for after you've cleared the bonus.
5. Keep an eye on your progress: Most casino dashboards will display your remaining wager required to meet the wagering terms. Check it at the start and end of each gaming session.

Final Thoughts: Know the Math, Make Better Choices

While wagering requirements are a necessary part of a bonus structure to prevent a casino from simply losing money on bonuses, players are often unable to fully decipher them. Most bonuses are designed with this in mind.

Some bonuses are designed to be unclear so only a small number of players actually benefit from them. Most players lose because of time restrictions, house edge, or confusing terms.

Knowing the numbers puts you at a distinct advantage. You can evaluate the expected value of a bonus, identify terms that are in players' favor, and discern when an offer is sub-optimal. This knowledge will serve you well.
