What Is a Casino Bonus?
Online casinos offer bonuses as incentives to attract new players and reward existing ones. While they can add genuine value, they come with conditions that are essential to understand before you accept them. Walking in with clear expectations is the best way to avoid disappointment.
Common Types of Casino Bonuses
Welcome Bonus (Match Deposit Bonus)
The most common promotional offer. The casino matches your first deposit by a percentage — typically 50% to 100% — up to a maximum amount. For example, a "100% match up to €200" bonus means if you deposit €200, you receive an additional €200 in bonus funds, giving you €400 to play with.
Free Spins
Free spins give you a set number of spins on a specified slot game at no cost. They may be offered standalone, as part of a welcome package, or as an ongoing promotion. Winnings from free spins are typically credited as bonus funds (not cash), subject to wagering requirements.
No Deposit Bonus
A small bonus (cash or free spins) awarded just for registering an account — no deposit required. These are smaller in value but carry lower risk since you're not committing your own money.
Reload Bonuses and Cashback
Reload bonuses are match bonuses for existing players on subsequent deposits. Cashback offers return a percentage of your net losses over a defined period, usually as bonus funds.
What Are Wagering Requirements?
Wagering requirements (also called playthrough requirements) define how many times you must bet through a bonus amount before any winnings can be withdrawn. This is the most important figure to evaluate when assessing a bonus.
Example: You receive a €100 bonus with a 30× wagering requirement. You must place €3,000 in total bets before the bonus converts to withdrawable cash.
How Wagering Requirements Are Applied
Different casinos apply wagering requirements differently — always read the terms:
- Bonus only: Wager requirement applies only to the bonus amount. (€100 bonus × 30 = €3,000 to wager)
- Bonus + deposit: Wager requirement applies to both. (€100 deposit + €100 bonus × 30 = €6,000 to wager)
- Winnings only: Less common — applies only to winnings generated from free spins.
Game Contribution Rates
Not all games contribute equally toward clearing a wagering requirement. Slots typically contribute 100%, but other games contribute less — or nothing at all.
| Game Type | Typical Contribution |
|---|---|
| Slots | 100% |
| Video Poker | 10%–20% |
| Blackjack | 5%–10% |
| Roulette | 5%–20% |
| Live Casino | 0%–10% |
Other Key Bonus Terms to Check
- Expiry date: Most bonuses expire within 7–30 days. Unused bonus funds and incomplete wagering are forfeited after this period.
- Maximum bet while bonus is active: Many casinos cap bets at €5–€10 per spin while you have an active bonus. Exceeding this can void your bonus and any winnings.
- Maximum withdrawal from bonus winnings: Some bonuses cap the amount you can actually cash out from bonus-derived winnings (e.g., max €100 withdrawal).
- Eligible games: Free spins and some bonuses are restricted to specific slot titles.
Is a Bonus Worth Taking?
A useful way to evaluate a bonus is to estimate its real value. Divide the bonus amount by the wagering requirement to get a rough expected value. A €100 bonus at 30× wagering = €3,000 in bets required. On a 96% RTP slot, you'd expect to lose about 4% per round, meaning roughly €120 in expected losses to clear — more than the bonus itself in many scenarios.
Lower wagering requirements (under 25×) and higher bonus amounts with fewer restrictions generally indicate better value. Always read the full terms before opting in.
