A free spin is a casino promotion that lets a player spin a slot machine reel once without using their own money. Free spins are awarded by online casinos as part of welcome bonuses, no-deposit offers, or loyalty rewards. Winnings from free spins are real money, usually subject to wagering requirements and maximum withdrawal caps.
How Do Free Spins Work?
When a casino credits a player with free spins, the spins appear in the player’s account, restricted to specific slot games. Each spin uses the slot’s pre-set bet value (typically €0.10 to €0.50 per spin, set by the casino — not the player). The player launches the eligible slot, and spins are consumed one at a time until the allocation runs out.
Winnings are added to a “bonus” balance, separate from any cash balance. Before that bonus balance can be withdrawn, you usually have to meet a wagering requirement — most commonly between 30x and 60x of your winnings.
Types of Free Spins
No Deposit Free Spins
Credited on registration with no deposit required. Typically 10 to 50 spins. These usually carry the highest wagering requirements (35x to 60x) and the lowest maximum win caps (€50 to €100). They’re the most popular acquisition offer in the Irish market. See current no-deposit free spins offers.
Welcome Bonus Free Spins
Credited alongside a deposit-match bonus. Typically 50 to 200 spins, often spread over multiple days. Wagering is usually lower (25x to 40x) and maximum win caps are higher (€500+).
Reload Free Spins
Awarded on later deposits as part of weekly or weekend promotions. Sometimes tied to specific new slot launches by the casino’s game providers.
In-Game Free Spins (Bonus Round)
Triggered inside the slot game itself by landing scatter symbols. These are part of the slot’s RTP calculation, not a casino promotion — but the term “free spins” applies to both, which is why we include them here.
VIP / Loyalty Free Spins
Awarded to high-volume players through casino loyalty programs. These typically come with the lowest wagering requirements and sometimes zero wagering.
Where Do Free Spins Come From?
Casinos pay slot providers a commission for every spin played. Providers like Pragmatic Play, NetEnt, and Play’n GO offer co-marketing budgets to push new slot releases, and casinos pass these spins to players as acquisition or retention incentives. The casino “loses” the cost of the spin but gains a registered player worth €50 to €200 in lifetime value, on average. That’s why free spins exist — they’re acquisition marketing, not charity.
Are Free Spins Really Free?
Yes and no. The spin itself is free — you don’t pay to play it. But winnings are subject to wagering requirements. If you win €20 from free spins with a 40x wagering requirement, you must wager €800 in total on eligible games before you can withdraw any of those winnings.
An honest worked example:
- Free spins won: €20
- Wagering requirement: 40x
- Total amount you must wager: €800
- Average Irish-facing slot house edge: ~4%
- Expected loss while clearing the wagering: ~€32
- Expected net result: €20 − €32 = −€12
On average, you’ll lose more than you win from a typical no-deposit free spins bonus. That doesn’t make them worthless — they’re a low-risk way to try a casino and you might get lucky on the wagering. But they’re not free money. Read our full wagering requirements guide for more worked examples.
How to Calculate the Value of a Free Spin
The expected value of a single free spin can be calculated as:
Value per spin = (Spin value × RTP) ÷ Wagering requirement
Example: A casino offers 50 free spins worth €0.20 each, on a slot with 96% RTP, with 40x wagering. The expected value per spin is (€0.20 × 0.96) ÷ 40 = €0.0048. So 50 free spins are worth approximately €0.24 in expected value.
Use this formula to compare offers honestly. An offer of 100 spins at €0.10 each with 60x wagering is worth (€0.10 × 0.96) ÷ 60 = €0.0016 per spin, or €0.16 total — less than the smaller 50-spin offer above.
How to Claim Free Spins
- Open the casino’s free spins offer page from a trusted comparison site like 24Spins.
- Click the offer to open the casino’s registration page in a new tab — verify the URL starts with
https://and matches the casino’s official domain. - Register an account using your real personal details. Irish-facing casinos require KYC (identity) verification before any withdrawal.
- Open the eligible slot game listed in the offer terms. Your free spins will be credited automatically. Some casinos require you to opt in via the promotions page first.
Best Slot Games for Free Spins

| Starburst | NetEnt | 96.09% | Low | Frequent small wins — keeps spins lasting longer |
| Gates of Olympus | Pragmatic Play | 96.50% | Very high | Bonus buy potential with multipliers |
| Big Bass Bonanza | Pragmatic Play | 96.71% | Medium | Fish multipliers in the bonus round |
| Sweet Bonanza | Pragmatic Play | 96.51% | High | Tumble feature gives extra spins in one |
Things to Watch Out For
- Time limits — most free spin offers expire within 24 hours to 7 days from being credited.
- Maximum win caps — winnings from free spins are often capped at €50 to €100, regardless of how much you actually win.
- Eligible game restrictions — only specific slots qualify; playing a different game won’t use your free spins.
- Country restrictions — verify your country isn’t on the casino’s excluded list before registering.
- Maximum bet limit during wagering — exceeding the bet cap (often €2 or €5) while clearing wagering will void the bonus and all winnings.
- Excluded deposit methods — paying with Skrill or Neteller often disqualifies you from welcome bonuses at Irish-facing casinos.
