How casino free spins work
How deposit-based free spins work, why they're tied to a specific slot, and what to check before activating.
Free spins (FS) are complimentary spins on a specific slot that a casino credits for registration, a deposit, or as part of a promotion. It looks like a "just because" gift, but free spins almost always come with the same kind of conditions as a cash bonus.
Deposit tiers
At most casinos in our ranking, deposit-based free spins scale in tiers — the bigger your deposit, the more spins you get. A typical structure looks like 25–35 FS for a €20 deposit, up to 500–600 FS for a €240 deposit. We've seen this pattern consistently across the casinos we've verified (IRIS, FUGU, MARTIN, FLAGMAN).
Why FS are locked to one slot
Free spins almost never let you pick any slot — they're tied to one specific game (for example "Fortuna TRUEWAYS", "Alice WonderLuck", or "Gold of Minos", depending on the casino and current promotion). That's standard practice: the casino arranges a promotional tie-in with a specific slot provider.
Maximum win caps
Winnings from free spins are usually capped — typically ×10 of the bonus's nominal value (so if the spins are worth a €20 equivalent bonus, the max win from them is €200). Anything won above that cap is removed once wagering is complete.
What to check before activating
- Which slot the free spins apply to — if you don't like that game, the offer is worth less than it looks.
- The wagering requirement on winnings — usually ×35 to ×40.
- The expiry window — free spins often need to be used within a limited time after crediting.
