Moon Princess free spins are worth about 9.65p each on average at 10p a spin, using Play'n GO's published 96.50% RTP, so 100 spins come to about £9.65. No partner currently names Moon Princess in its welcome offer. This page sets out the value, the cascading grid, the in-game feature and the closest real spin offers.
100 Moon Princess spins at 10p have a face value of £10 and average about £9.65 back.
A cascading 5 × 5 grid means one spin can produce several wins in a row.
Moon Princess 100 is a different game: 96.2% top RTP and a 15,000x max win.
With 10x wagering, the average kept from 100 spins falls to about £6.27.
None of our partners offers Moon Princess spins or a no-deposit bonus.

Moon Princess free spins: what the term covers
Moon Princess free spins can mean a casino promotion or a feature inside the slot. A promotion gives you a set number of spins at a fixed stake once you meet its condition, with terms on expiry, wagering and eligible games. An in-game feature is part of the slot's design and is identical at every casino running the same version. The first is something you choose to claim; the second is something you might land.
Both are covered here. The free spins hub lists the spin offers we currently compare, and bonus spins vs free spins explains why casinos use different names for similar things.
Cascades: why one Moon Princess spin can pay more than once
Moon Princess uses a 5 × 5 grid with cascading wins. When symbols form a win, they are removed and new symbols fall into the gaps, which can create another win from the same spin. Each casino free spin is a single stake, but it can produce a chain of results before the next spin starts.
Cascades don't change the long-run return; they are already part of the 96.50% figure. What they change is the shape of results: many spins end with nothing, while some chain several wins. That pattern fits the game's high volatility rating. Our cluster pays slots page covers similar grid games.
Moon Princess free spins value: the numbers
At 96.50% RTP, each 10p spin returns about 9.65p on average and the house edge is 0.35p. Here's how that scales with offer size and stake.

As the last two rows show, spins at a higher stake give the same average for the same face value, with a higher ceiling and fewer chances. Read more in free spins value, and in coin value for how stake is set on an offer.
Moon Princess vs Moon Princess 100
Play'n GO released a follow-up, Moon Princess 100, in 2022. It's a separate game with its own figures, so a free spins offer on one doesn't apply to the other.

On average the two are within a few pence per 100 spins. The sequel has a much higher stated ceiling, which usually means more of its return sits in rare large wins. Our page on Moon Princess 100 free spins covers it in full.
How to trigger free spins on Moon Princess
The in-game free spins, the trigger and any special powers are described in the game's help screen. We couldn't confirm these details from the developer for this page, so we don't restate them; the help screen is the correct source for the version you open. UK technical standards require rules, game descriptions and payouts to be available before you play.
Open Moon Princess and go to the information or paytable menu.
Confirm the RTP: 96.50% is the published figure.
Find the free spins section and note what triggers it and how many spins it gives.
Check any special features listed for the round and whether spins can be added.
If you are playing offer spins, confirm in the terms how feature winnings are treated.
Features can't be bought at UK-licensed casinos, so the round is only reached from normal spins, including casino free spins. The question can free spins trigger the bonus round covers the usual treatment of the winnings.
Moon Princess free spins no wagering vs wagering
Since 19 January 2026, wagering on UK bonuses has been capped at 10x, under rules the Gambling Commission announced (opens in a new tab) to make promotions safer and simpler. Even at that cap, wagering takes a noticeable share of spin winnings.
100 spins at 10p: wagering on Moon Princess and Moon Princess 100
No partner of ours offers a no-deposit bonus, so Moon Princess free spins with no deposit aren't available from them. Every partner spin offer needs a deposit of £10 or more, or a £10 qualifying slots bet. Where no-deposit spins appear elsewhere, read the cap on winnings and the expiry first, and make sure the site holds a Gambling Commission licence. The page do no-deposit bonuses still exist gives an honest picture.
Moon Princess bonus terms: what to look for
Check whether Moon Princess, or Moon Princess 100, is named in the eligible games.
Work out the face value: spins × stake per spin.
Find the deadline to accept the spins, then the deadline to use them.
Check for wagering on winnings and confirm it's no more than 10x.
Look for a cap on spin winnings below the game's 5,000x.
Confirm your payment method qualifies for the offer.
A spin offer on Moon Princess is worth roughly its face value minus 3.5%, and less with wagering. That's a modest amount of extra play rather than a gain. Bonuses don't change a game's odds, and over time the house edge makes losses the likely result. If an offer would lead you to deposit more than planned, it's worth passing on; when to say no to a bonus covers the signs.

Frequently asked questions
What is the Moon Princess RTP?
Play'n GO publishes Moon Princess at 96.50%, so a 10p spin returns about 9.65p on average over a very large number of spins, with a house edge of 3.5%. Casinos can run different settings, so the figure in the game's information screen is the one to rely on. In a short session, results can be far from the average. See the RTP glossary entry for what the percentage does and doesn't tell you.
How do you trigger free spins on Moon Princess?
The trigger and how the round plays are set out in the game's help screen, which is the source to rely on for the version you open. Check the free spins section before your first spin. The round can't be bought at UK-licensed casinos, so it only comes from normal spins, which include casino free spins. Our how do free spins work answer explains how in-game and casino spins differ.
Can I get Moon Princess free spins with no deposit?
Not from our partners, because none of them offers a no-deposit bonus. Their spin offers need a deposit of at least £10 or a £10 qualifying slots bet. No-deposit spins on named slots are uncommon at UK-licensed casinos and usually come with low caps on winnings and short time limits, plus identity checks before play. Our guide to free spins with no deposit explains what's realistic.
Are Moon Princess free spins no wagering worth more?
Yes. With no wagering, 100 spins at 10p average about £9.65 in cash. With 10x wagering, you'd need to stake £96.50, which costs around £3.38 at the game's house edge, leaving about £6.27 on average. The 10x limit has applied to UK bonuses since 19 January 2026. The comparison wager-free spins vs wagering spins sets out the difference across offer types.
What is the difference between Moon Princess and Moon Princess 100?
They're separate Play'n GO games. Moon Princess has a 96.50% RTP, a cascading 5 × 5 grid and a 5,000x max win. Moon Princess 100, released in 2022, has a 96.2% top RTP, pays for 3 or more matching symbols in a row or column and lists a 15,000x max win. Per 100 spins at 10p, the averages differ by about 3p. See Moon Princess 100 free spins.
What does cascading mean in Moon Princess?
When a win forms, the winning symbols are removed and new ones drop into the gaps, which can create another win from the same spin. A single casino free spin can therefore pay more than once. Cascades are already built into the game's 96.50% RTP, so they don't raise the average return; they change how wins are spread. The free spins maths guide explains how features fit into the average.
What is the Moon Princess max win?
The listed max win is 5,000 times the stake, which is £500 on a 10p spin and £5,000 on a £1 spin. Reaching it is extremely rare. A casino offer can also set a lower cap on spin winnings, which applies first. Check the game's help screen for how the cap is applied during features. For where caps appear in offer terms, see free spins max win.
Do Coral or Ladbrokes free spins work on Moon Princess?
Only if Moon Princess is in the list of selected games on the promotion page, which we don't assume. Coral gives 100 spins at 10p after a £10 slots bet and Ladbrokes up to 500 spins at 10p over 10 days after spending £10 on slots, both with no wagering on winnings and both for new customers aged 18+. Check the Ladbrokes eligible games page for how the list is set.
How long do Moon Princess free spins last?
That depends on the offer, not the game. Spin offers usually have one deadline to accept the spins and another to use them. Coral's welcome spins, for example, must be accepted within 48 hours and used within 7 days, and Ladbrokes' daily batches must be claimed by 23:59 and used within 7 days. Unused spins are lost after expiry. Typical windows are covered in free spins expiry.
Is Moon Princess high volatility?
Yes, it's listed as high volatility. That usually means many spins pay little or nothing and larger wins arrive less often, sometimes from chains of cascades. Over 50 or 100 casino spins, results vary widely between batches. Volatility doesn't change the average return, which is set by the 96.50% RTP. The free spins low vs high volatility slots comparison explains what to expect.
