Online casinos compete for players with ever-more-generous bonuses. But the flashy numbers usually hide tough conditions. Let's break down the main bonus types on offer in 2026 and explain what actually matters — see our [bonus catalogue](/bonuses) for current offers.
Welcome bonus: only good on paper
The welcome bonus is the most common type. Usually 100% or 200% of your first deposit plus free spins. For example, €200 + 100 FS. Sounds good — but the key parameter is wagering: without understanding it, the bonus is worth nothing.
Wagering: the one number that matters
The wagering requirement is the bonus turnover coefficient. A x30 wagering means: if you got a €100 bonus, you need to stake €3,000 before you can withdraw any winnings tied to the bonus. The lower the wagering, the better the bonus.
Separately, look at which games contribute to wagering. Slots usually count 100%, but blackjack and roulette often count 10% — or 0%. That can completely change the bonus math.
Free spins: cortesy rounds with fine print
Free spins are complimentary rounds on specific slots. Watch the winnings cap: some casinos limit the maximum you can withdraw from free-spin winnings (say €20–€50). Check which slots the spins run on — sometimes it's only 'weak' games with 92–94% RTP.
Reload bonus for regulars
The reload bonus is for regular players — typically weekly or monthly. Smaller than the welcome (10–50% of deposit) but with lower wagering (often x15–x25). Frequently the best option for experienced players who deposit regularly.
No-deposit bonus: small but risk-free
A no-deposit bonus is rare: the casino gives €5–€20 or 20–50 free spins without a deposit. A good way to test the platform risk-free, but hard to actually win from because of the max-payout cap (€50–€100).
How to compare: the real-value formula
- Multiply the bonus by the wagering coefficient (e.g. €100 × x30 = €3,000 of turnover).
- Calculate RTP loss: €3,000 × (1 − 0.96) = €120 of expected loss.
- Compare the 'net' bonus: €100 (bonus) − €120 (expected loss) = −€20. This bonus is a loss!
- Look for bonuses where the 'net' result is positive — usually x15–x25 wagering on 97%+ RTP slots.
