Free spins are casino promotions that allow players to make a set number of slot spins without paying the normal cash stake for each promotional spin.
For example, a casino may offer: 20 free spins worth €0.20 each
The player can use those spins on an eligible slot without paying €0.20 from their cash balance for each one.
But “free spins” does not always mean that any winnings are immediately withdrawable.
The promotion may specify which game can be played, how much each spin is worth, when the spins expire and what happens to any winnings. Some offers may also apply wagering requirements or other restrictions to money won from the spins.
The important thing is to separate the free spin itself from the money that may be won from it.
What Are Free Spins?
Free spins are promotional slot game rounds funded by the casino rather than directly by the player’s cash balance.
They are a type of casino bonus.
The UK Gambling Commission includes free spins on specific games within its definition of bonus benefits provided by gambling operators.
A promotion might provide:
10 free spins
20 free spins
50 free spins
100 free spins
But the number alone does not show the full value of the offer. You also need to know the value of each spin.
For example: 50 free spins × €0.10 = €5 promotional spin value while: 50 free spins × €0.50 = €25 promotional spin value
Both promotions advertise 50 spins. Their nominal playing value is very different.
How Do Free Spins Work?
The exact process depends on the casino, but a typical free-spin promotion works like this.
1. The Player Qualifies for the Offer Qualification may require:
opening a new account
making a deposit
entering a bonus code
opting into a promotion
completing another qualifying activity
Some free-spin offers are available without a deposit. Others are part of a larger welcome bonus.
2. The Spins Are Added to the Account The casino credits a set number of promotional spins. For example: 30 free spins
The offer may restrict those spins to one particular slot or a selected group of games.
3. Each Spin Has a Defined Stake Suppose each promotional spin is worth: €0.20
The player can make the qualifying spins without the €0.20 stake being deducted from the normal cash balance.
4. The Slot Produces Normal Game Results Each promotional spin uses the game’s normal mechanics.
The result may:
lose
produce a small payout
trigger a bonus feature
produce a larger win
The fact that the spin is promotional does not mean it must win.
5. Winnings Are Credited According to the Promotion This is where free-spin offers can differ significantly.
Winnings might:
become withdrawable cash
enter a bonus balance
require additional wagering
be subject to a conversion limit
The promotion’s terms determine what happens next.
Are Free Spins Really Free?
The spin itself can be free in the sense that the player does not pay the normal stake from their own balance.
But this does not mean the promotion has no conditions.
Free spins can still have rules covering:
qualifying deposits
eligible slots
spin values
expiry periods
wagering requirements
maximum winnings
withdrawal conditions
This distinction matters because the phrase “free spins” can make an offer sound simpler than it really is.
UK Gambling Commission research found that consumers can perceive free spins and similar promotions as having little or no risk because they do not initially require the same direct cash stake. The regulator also noted that some free-spin offers can still have wagering conditions attached.
So the word free describes the promotional game round. It does not automatically describe everything that happens afterward.
What Is Free Spin Value?
The value of a free spin is the stake assigned to each promotional game round.
For example: 20 free spins at €0.20 each Nominal playing value: 20 × €0.20 = €4
Another offer could provide: 20 free spins at €1 each Nominal playing value: 20 × €1 = €20
This shows why comparing free-spin offers only by the number of spins can be misleading.
A promotion with 100 very small spins may have less nominal playing value than another offer with 25 larger spins.
Always check: Number of spins × stake per spin
Does the Free Spin Value Affect How Much You Can Win?
Usually, yes.
Slot prizes are often calculated in relation to the stake.
A higher promotional spin value can therefore create different possible payout amounts from the same game.
Suppose a fictional slot awards: 20× stake for a particular result.
At a €0.10 free-spin value: €0.10 × 20 = €2
At a €0.50 free-spin value: €0.50 × 20 = €10
The exact result still depends on the game’s paytable and rules. This is why the stake value attached to free spins is an important part of the promotion.
Which Slots Can You Use Free Spins On?
Some promotions allow free spins on only one slot.
For example: 50 free spins on Slot A
Other promotions may allow a choice from a group of games. The casino may also assign free spins automatically when the eligible game is opened.
Players should not assume that promotional spins can be transferred to any slot on the website.
Check:
eligible game
eligible game list
required provider
activation instructions
If the offer is restricted to one game, playing another slot will normally use ordinary funds rather than the promotional spins.
Do Free Spins Use the Normal Slot RNG?
Promotional free spins generally operate within the same slot game mechanics used for ordinary paid rounds.
An RNG-based slot still relies on its random-number-generation and game mathematics to determine outcomes.
The promotional difference is normally who funds the stake, not that the player receives a special guaranteed result.
A free spin can therefore:
lose
win less than the nominal stake
win more than the nominal stake
trigger a feature
There is no requirement for each free spin to return money. “Free spin” does not mean “winning spin.”
What Happens to Free Spin Winnings?
This is one of the most important parts of the offer.
Imagine a promotion gives: 20 free spins and those spins produce: €15 in winnings
What happens to the €15? There is no universal answer.
Option 1: Winnings Become Cash The €15 may become unrestricted funds according to the promotion.
Option 2: Winnings Become Bonus Funds The €15 may enter a bonus balance and remain subject to wagering requirements.
Option 3: Only Part Becomes Withdrawable The promotion may include additional conversion rules or limits.
The UK Gambling Commission distinguishes between normal deposit balances and bonus balances. Winnings created from bonus benefits can remain within a bonus balance while wagering conditions are incomplete.
This is why free-spin winnings should not automatically be treated as cash until the promotion explains their status.
Can Free Spin Winnings Have Wagering Requirements?
Yes, depending on the promotion and jurisdiction.
Suppose free spins produce: €20 in bonus winnings and the offer applies: 10× wagering
The required qualifying wagering would be: €20 × 10 = €200
The player would have to complete €200 in qualifying wagers before those restricted funds could become withdrawable under that example.
Importantly, this does not mean completing €200 of wagering guarantees that €20 remains.
Casino games still produce wins and losses while the wagering is being completed.
Current Wagering Rules in Great Britain
Bonus regulations differ by country.
Great Britain currently provides a useful example.
Since January 19, 2026, applicable UK Gambling Commission licensees cannot apply wagering requirements above 10 times bonus funds. Current rules also require incentive terms to be clear, transparent, fair and readily accessible.
Free spins can fall within the regulator’s broad rules covering incentives and bonuses.
This is a Great Britain-specific rule. It should not be treated as a worldwide limit.
A free-spin promotion offered under another regulatory system may follow different rules.
Do Free Spins Expire?
Often, yes.
A free-spin promotion may specify that the spins must be used within:
24 hours
several days
one week
another defined period
These are only examples. The actual deadline comes from the individual promotion.
There may also be separate deadlines. For example: Claim free spins within 7 days but: Use them within 48 hours after activation
Any resulting bonus funds might then have another expiry period.
This is why the terms should be checked before activating the offer.
What Happens to Unused Free Spins?
If promotional spins expire before they are used, they may simply disappear from the account.
For example: 20 spins credited 12 spins used 8 spins remaining when the offer expires
The remaining eight spins may be lost.
This is different from losing money through game results. The promotional entitlement itself has expired.
Exact treatment depends on the offer.
Can Free Spins Have a Maximum Win?
Some promotions may limit the amount that can ultimately be converted or withdrawn from promotional free-spin winnings.
For example, an offer could provide a fixed number of spins but apply a separate limit to bonus winnings.
This is not universal. If such a condition exists, it should be clear in the promotion’s terms.
Maximum-win limits can materially change the value of an offer, particularly if the slot itself is capable of producing much larger prizes.
Never assume that the slot’s normal maximum payout automatically equals the amount that can be withdrawn under a promotional free-spin offer.
What Are Deposit Free Spins?
Deposit free spins are awarded after making a qualifying deposit.
For example: Deposit €20 and receive 30 free spins
The promotion may require:
a minimum deposit
a particular payment method
an opt-in
a bonus code
account verification
The spins are part of a deposit-based promotion even though no additional stake is normally required for each promotional spin.
What Are No-Deposit Free Spins?
No-deposit free spins do not require a deposit to receive the promotional spins.
They may be awarded for:
creating an account
completing verification
participating in a promotion
another qualifying action
However: No deposit does not mean no terms.
The free spins may still have:
expiry dates
game restrictions
fixed spin values
wagering rules for winnings
other promotional conditions
The absence of a deposit requirement removes only one potential condition.
What Are Welcome Bonus Free Spins?
Free spins are often included in casino welcome packages.
For example: 100% deposit bonus up to €100 + 50 free spins
These are really two promotional components: Deposit bonus and: Free-spin bonus
They may not necessarily follow identical rules.
The deposit bonus could have one wagering requirement while the free-spin winnings are handled differently.
Similarly, the two promotional components can have different expiry dates.
Players should therefore read each part of a combined welcome offer separately.
What Are Daily Free Spins?
Some casinos use free spins as recurring promotional rewards.
These may be described as:
daily free spins
weekly free spins
loyalty spins
reward spins
The qualification rules can vary.
For example, the promotion could depend on:
logging in
qualifying play
loyalty status
another promotional condition
The UK Gambling Commission has noted that free spins and similar offers can become recurring parts of players’ gambling journeys and has examined how “daily” promotional framing can encourage repeated engagement.
This is one reason free spins should still be considered gambling promotions rather than automatically risk-free rewards.
What Is the Difference Between Free Spins and Bonus Spins Inside a Slot?
These terms can describe two very different things.
Promotional Free Spins
These are provided by the casino as a marketing offer. For example: Register and receive 20 free spins
In-Game Free Spins
These are part of the slot’s normal game design. For example: Land three Scatter symbols and trigger 10 free spins
The second type is a game feature, not necessarily a casino promotion.
The UK Gambling Commission’s guidance distinguishes promotional bonus activity from some generic game features that are available within the underlying game itself.
This distinction helps avoid confusion.
A slot’s built-in free-spins round is part of its mathematics and RTP. A promotional free-spin offer is an external reward provided by the operator.
Do In-Game Free Spins Affect RTP?
Built-in free-spin features can form part of a slot’s mathematical design.
For example, if a slot’s bonus round is triggered during ordinary play, the prizes generated by that feature can contribute to the game’s theoretical RTP.
Promotional spins are different.
Giving a player 20 promotional spins does not normally change the underlying RTP of the slot itself. The game still follows its existing mathematical model.
The casino is simply funding those particular rounds.
Can You Choose the Stake on a Free Spin?
Often, no.
Promotional free spins commonly come with a fixed stake. For example: €0.20 per spin
The player may therefore be unable to change the stake to: €0.10 or: €1 while using the promotional spins.
This allows the operator to define the value of the offer clearly. If changing the stake is allowed, the terms should explain how the promotion works.
Can You Change the Slot While Using Free Spins?
That depends on the offer.
If the free spins are tied to one game, they normally cannot be moved to another slot.
If the promotion covers several eligible games, the player may have more flexibility.
Before opening a different slot, check whether:
the remaining promotional spins transfer
the new game qualifies
ordinary cash will be used instead
This avoids accidentally placing paid wagers when the player expected to use promotional spins.
How to Calculate the Nominal Value of Free Spins
A basic calculation is simple: Number of Spins × Value Per Spin = Nominal Spin Value
For example: 20 × €0.20 = €4 50 × €0.20 = €10 100 × €0.10 = €10
Notice the last two examples.
A promotion offering: 50 spins at €0.20 and another offering: 100 spins at €0.10
both have a nominal spin value of: €10
This demonstrates why the number of spins alone is not enough for comparison.
Does Nominal Spin Value Equal Cash Value?
No.
Suppose a promotion provides: 50 spins × €0.20 = €10 nominal spin value
That does not mean the casino has placed €10 cash into the player’s account.
The €10 represents the value of the stakes funded by the promotion.
The actual result could produce: €0 €3 €10 €50 or another amount.
Any resulting winnings may then be subject to the offer’s terms.
Nominal spin value and withdrawable cash value are therefore different concepts.
Are More Free Spins Always Better?
Not necessarily.
Compare:
Offer A 100 free spins at €0.05 each Nominal value: €5
Offer B 25 free spins at €0.50 each Nominal value: €12.50
Offer A has four times as many spins. Offer B has more than twice the nominal stake value.
There could also be differences in:
eligible slot
RTP
volatility
wagering requirements
expiry
maximum winnings
This is why “100 FREE SPINS” should not automatically be considered better than “25 FREE SPINS.”
The full structure matters.
Do Free Spins Guarantee Winnings?
No.
A promotional spin can lose just like a normal slot spin.
Suppose a player receives: 50 free spins
It is possible for those spins to generate little or no return. It is also possible for them to produce a larger prize.
The outcome is uncertain.
Free spins remove the direct stake for those particular promotional rounds. They do not remove the randomness of the slot.
Are Free Spins Safer Than Using Cash?
Free spins can reduce the amount of a player’s own money directly staked on those particular rounds.
But that does not automatically make the wider promotion risk-free.
For example, a promotion could encourage additional gambling after the free spins are used. Free-spin winnings may also require further wagering before becoming withdrawable.
UK Gambling Commission research found that consumers often viewed free-spin promotions as low-risk because their own money was not directly required for the initial spins. The regulator highlighted that this perception can make these promotions feel simpler and more immediately attractive than they actually are.
Free spins should therefore be treated as a gambling promotion, not as guaranteed value.
What Should You Check Before Accepting Free Spins?
A useful free-spin offer should be understandable without guesswork.
Check the following:
Number of spins — How many promotional rounds are provided?
Value per spin — Is each spin worth €0.10, €0.20, €1 or another amount?
Eligible game — Which slot can be played?
Qualification — Is a deposit, bonus code or opt-in required?
Expiry — How long are the spins available?
Winnings treatment — Do winnings become cash or bonus funds?
Wagering — Must the winnings be played through before withdrawal?
Maximum winnings — Is there a promotional conversion or withdrawal cap?
These conditions are more useful than the word “FREE” printed in large letters on an advertisement.
Common Free Spins Misconceptions
“50 free spins means I receive 50 guaranteed wins.” No. It means 50 promotional game rounds. Each individual spin can win or lose.
“Free spins are the same as cash.” No. The casino funds the stake on the promotional spins. Their nominal value is not automatically credited as withdrawable cash.
“Any winnings are immediately withdrawable.” Not necessarily. The promotion may apply wagering or other conditions.
“100 free spins are always better than 20.” No. Spin value and promotional conditions also matter.
“No-deposit free spins have no conditions.” Not necessarily. They can still include expiry, game restrictions and rules around winnings.
“Promotional free spins and a slot’s bonus round are the same thing.” No. Promotional free spins are provided by the casino. An in-game free-spins feature is part of the slot’s normal mechanics.
Free Spins Should Not Change Your Gambling Budget
A promotion can feel like extra value because the casino funds the initial spins.
But the promotion should not become a reason to keep gambling after the spins are finished.
For example, losing all free-spin winnings does not create a reason to deposit money to “win them back.”
Likewise, receiving bonus winnings with a wagering requirement does not mean the requirement must be completed at any cost.
Casino outcomes remain uncertain.
A free-spin offer should be treated as an optional promotion within an existing entertainment budget, not as a reason to spend more than originally intended.
Final Thoughts
So, what are free spins in online casinos?
They are promotional slot rounds where the casino provides the stake instead of deducting it directly from the player’s normal cash balance.
A free-spin offer can be summarized as: Number of spins + value per spin + eligible game + rules for winnings
For example: 50 spins × €0.20 = €10 nominal promotional spin value
But that €10 is not the same as €10 cash.
The spins still produce uncertain slot outcomes, and any winnings may be subject to wagering requirements, expiry rules or other promotional conditions.
This is why the most important question is not simply: “How many free spins do I get?”
It is: “How much is each spin worth, and what happens to anything I win?”
Once those two points are clear, the real structure of a free-spin promotion becomes much easier to understand.
