What Are Casino Bonuses?

Casino bonuses are promotional offers designed to attract new players and encourage continued play. The most common types include:

While bonuses provide extra playing funds, they come with conditions—most importantly, wagering requirements. Understanding these terms is essential to avoid frustration and set realistic expectations.

Wagering Requirements Explained

Wagering requirements (also called "playthrough" or "rollover") specify how much you must bet before you can withdraw bonus funds or winnings derived from bonus funds.

The Math

A typical wagering requirement is expressed as a multiplier, such as 30x, 35x, or 40x. This multiplier applies to either:

Example 1: Bonus-Only Wagering (30x)

Scenario: You deposit €100 and receive a €100 bonus (100% match). Wagering requirement: 30x bonus.

Example 2: Bonus + Deposit Wagering (35x)

Scenario: You deposit €100 and receive a €100 bonus. Wagering requirement: 35x (bonus + deposit).

Game Contribution Percentages (Weighting)

Not all games contribute equally to wagering requirements. Casinos assign different game weightings to prevent bonus abuse on low-variance games:

Game Type Typical Contribution Example
Slots 100% €10 bet = €10 toward wagering
Scratch Cards 100% €10 bet = €10 toward wagering
Table Games (Roulette, Blackjack) 10-20% (or excluded) €10 bet = €1-€2 toward wagering
Live Casino 10% (or excluded) €10 bet = €1 toward wagering (if allowed)
Video Poker, Some Slots 0-50% Varies by game; check terms

Why Weighting Exists

Slots have high house edge and variance, making them risky for bonus clearing. Table games like blackjack have low house edge (~0.5-1% with optimal play), so allowing 100% contribution would let players clear bonuses with minimal risk. Weighting balances this.

Max Bet Rules

Most bonuses include a maximum bet restriction while wagering is active. Common limits:

Exceeding the max bet even once can void your bonus and winnings. This rule prevents players from making large bets to quickly clear wagering (which could exploit variance).

How Max Bet Violations Happen

Solution: Set your bet size at or below the max limit and don't change it during bonus play.

Restricted Games

Bonus terms often exclude certain games entirely. Playing restricted games with bonus funds can void the bonus. Commonly restricted:

Many casinos block restricted games during bonus play (you'll see a message if you try to open them). Others don't block them but void your bonus if you play them—read the terms carefully.

Time Limits

Bonuses typically expire if wagering isn't completed within a set timeframe:

After the time limit expires, the bonus and any associated winnings are forfeited. If you've partially completed wagering, your progress is lost.

Example

You have a €100 bonus with 30x wagering (€3,000 total) and 14 days to complete it. If you've only wagered €1,500 by day 14, the bonus and all winnings from it are voided.

Calculating Realistic Bonus Value

Bonuses are not "free money"—they have expected value that depends on house edge, wagering requirements, and game selection.

Formula for Expected Value (Simplified)

EV ≈ Bonus Amount - (Wagering Required × House Edge)

Example

Bonus: €100 with 30x wagering (€3,000 total)
Game: Slot with 4% house edge (96% RTP)

Expected loss during wagering: €3,000 × 0.04 = €120
Expected value: €100 (bonus) - €120 (expected loss) = -€20

In this scenario, completing the wagering has a negative expected value. You'd need to get lucky (win above expectation) to profit.

When Bonuses Have Positive Value

Common Bonus Terms to Watch For

Max Withdrawal Cap

Some bonuses (especially no-deposit bonuses) limit how much you can withdraw even after completing wagering:

Sticky vs. Non-Sticky Bonuses

Most bonuses are sticky, meaning the initial bonus amount is deducted upon withdrawal.

Deposit + Bonus Locked Together

Some casinos lock your deposit and bonus together until wagering is complete. This means you can't withdraw your deposit early without forfeiting the bonus. More player-friendly casinos allow you to cancel the bonus and withdraw your deposit anytime.

Responsible Bonus Use

Bonuses can enhance entertainment value, but they should not be chased as "profit opportunities." Here's how to use them responsibly:

1. Read the Full Terms

If terms are unclear or hidden, it's a red flag.

2. Calculate Time Investment

Completing 30x wagering on €100 (€3,000 total) at €1 per spin = 3,000 spins. At 10-15 seconds per spin, that's 8-12 hours of play.

Ask yourself: Is this worth my time for the potential return?

3. Don't Chase Bonuses to "Get Your Money Back"

If you've lost money, taking a bonus to try to recover is a form of chasing losses—a dangerous pattern. Bonuses don't improve your odds; they extend play time.

4. Use Bonuses for Entertainment, Not Income

Treat bonuses as extended play time with your own deposited funds, not as a path to profit. The expected value is usually neutral or slightly negative.

5. Know When to Decline a Bonus

If you prefer flexibility (quick withdrawals, unrestricted play), decline the bonus. You're not obligated to accept promotional offers.

Swedish Market: Bonus Restrictions

Sweden's gambling regulations impose strict limits on bonus advertising and structure:

As a result, Swedish-licensed casinos often have smaller, simpler bonuses compared to less-regulated markets. This is by design, emphasizing responsible gambling over promotional intensity.

Summary: Using Bonuses Wisely

Casino bonuses extend playtime but come with conditions that reduce (or eliminate) their expected value. Understanding wagering requirements, game weighting, max bet rules, and time limits helps you decide whether a bonus is worth accepting.

Use bonuses as entertainment enhancements, not profit strategies. Read the full terms, calculate the time investment, and never take bonuses to chase losses. When in doubt, declining a bonus gives you maximum flexibility and control over your funds.
