Best free spins casinos 2026

Free spins are one of the most popular bonuses in the online casino world. Plenty of online casinos hand them out, because the bonus is simple and easy to understand, and it isn't expensive for the casino offering it.

In this review we'll look at free spins and free spins casinos in a bit more detail. We'll cover when free spins are handed out at all, how to improve your chances of winning from them, and briefly run through several online casinos that give players free spins and are well regarded for their reliability and safety.

What are free spins?

Before using free spins, every player needs a clear idea of what they actually are. Free spins are spins on online casino slot machines that cost the player nothing. They are the casino's gift to the player, intended to encourage them to keep playing and to make deposits. It's a way of retaining players and keeping them engaged.

It's worth stressing that free spins are only possible on slots, since other online casino games simply have no spin to give away. Free spins are usually offered on the best-known slots, such as Starburst or Gates of Olympus.

What is a free spins casino?

Any online casino able to give players free spins can be called a free spins casino. So a free spins casino isn't one particular site — it's every casino online with the functionality and the licence to award free spins to its players.

It's important to stress that no online casino operating under a New Zealand licence can call itself a free spins casino, because domestic operators can't run online casino games at all. TAB NZ or Lotto NZ, for instance, won't be able to give you free spins — so free spins casinos are only those online casinos registered and regulated offshore.

When are free spins awarded?

Online casinos award free spins in different situations and for different reasons. Mostly it's to attract new customers and to keep existing players engaged. Below we run briefly through the main situations in which online casinos hand players free spins.

No-deposit sign-up bonus

Free spins are often awarded as a no-deposit sign-up bonus. In that case a player only has to register and can try the casino out completely free. Different online casinos offer different numbers of spins for signing up. Some award as few as 10 spins, others give 50 or even 100.

If you want to try a free spins casino with spins awarded purely for registering, look closely at the main bonus terms — check which game the spins apply to, what a single spin is worth, what the maximum win is, and weigh up similar details.

Free spins as part of a bonus

Most online casinos have a Welcome Package or Welcome Bonus. These are deposit bonuses, but free spins are often bundled in. A welcome bonus at an online casino might read something like: a 150 per cent bonus and 100 free spins. In that case the free spins are simply an add-on to the bonus.

Free spins don't have to be attached to a first-deposit bonus — they can also come with weekly or personal bonuses. That said, welcome package free spins are usually worth more, so they're the ones to pay particular attention to.

Free spins for active players

Online casinos often award free spins to active players as an incentive to come back and play. It's a way of showing players some attention and reminding them the casino is there.

Players themselves often approach an online casino asking for a bonus. In that case they're usually given free spins, since from the casino's point of view this is about the cheapest bonus there is.

Free spins are also frequently given not to active players but, on the contrary, to inactive ones. The online casino is effectively trying to wake the player up, in the hope that once they have free spins they'll come back to play and start depositing again.

Free spins on new slots

The best online casinos are constantly expanding their range of slots. Having added new games, a casino wants to popularise them, so all — or at least some — players are offered free spins on a new title. The casino can then draw conclusions, because the numbers show whether players stayed on to play the new slots, or whether they simply weren't interested.

Giving away free spins on new slots often costs an online casino nothing: the game providers themselves cover the cost, because they have just as much interest in seeing a new game become a player favourite.

How do you pick the best free spins casinos?

Plenty of different online casinos can and do offer players free spins, but at some of them those spins are worth more — so it pays to choose the free spins casinos where the spins on offer can bring a player the greatest value.

Below we run briefly through the main things to look at when choosing a free spins casino.

Spins with no deposit

It's important not to be caught out: check that the casino really is offering free spins with no deposit at all. Casinos sometimes play games with the wording, claiming the spins are free when in fact a deposit turns out to be required. Where free spins genuinely come with no deposit, then even if the bonus terms are demanding, at least you aren't risking your own money.

That's why players often build free spins into their playing strategy — it's one thing that cannot lose you money directly.

The number of free spins offered

It's also important to note exactly how many free spins are on offer. One operator might give just a handful, while elsewhere you'll get 50, 100 or even more. Bear in mind that spins go quickly, so if you only get a few, your chances of winning anything from them are slim.

The best online casinos award more free spins, which lets players get a proper feel for the game itself.

The game the free spins apply to

Free spins are awarded on one specific online casino game. Before accepting free spins, a player should always check which game they apply to.

Most online casino players like to play games from the leading providers — for example, Pragmatic Play, Play‘nGO and so on. So check whether the game the free spins apply to actually looks interesting to you, look at its RTP (the theoretical return to player percentage) and so on.

Wagering requirements

The most valuable free spins are those with no wagering requirement at all. In that case a player is effectively playing with real money, since the whole amount won can be withdrawn to a bank account or e-wallet. Free spins without wagering requirements are fairly rare, though.

It's important to check exactly what the wagering requirements are. Operators often set 40x or even higher, so if you see a requirement below that figure, the odds of actually winning something from the free spins are realistic.

Maximum win

It's also important to read up on the maximum you can win from free spins. The very best online casinos don't cap the win at all; other good casinos online set a competitive maximum.

There are also online casinos that let you win only a very small amount from free spins — €10 or €20, say. The casino's argument is that the bonus is entirely free, so any win is a good one. The operators have a point, up to a point — but free spins with a capped maximum win are the least valuable kind for a player.
