Phoenix Sun slot review

Is the Phoenix Sun slot worth playing?

Phoenix Sun suits players who like a single, clear mechanic they can follow on a small screen. You start with 243 ways, a Phoenix Wild can open more of the grid, and a fully open grid sends you into free spins. There is no stack of side features to learn.

It comes from Quickspin, the Stockholm studio owned by Playtech since May 2016 and best known for Big Bad Wolf and Sakura Fortune. Medium volatility and a 96.08% default RTP put it in the middle of the pack: not a gentle low-variance game, not a wild swing either.

The main gap in the published data is the top prize. We could not verify a maximum win, so look in the game's paytable inside your app before you decide on a stake.

Phoenix Sun specifications

The word 'default' matters. A studio can offer casinos lower RTP settings as well, and the Gambling Commission's RTS 3 rules on game descriptions (opens in a new tab) require the game's rules and return information to be available to you. Our guide to finding a game's RTP in an app shows where that usually sits.

How the features work in Phoenix Sun

The design is built around rows that are locked at the start. Above the visible 5×3 reels sit rows you can't use yet. Casinos.com's Phoenix Sun page (opens in a new tab) describes the same set-up; here it is in our words.

Blocked rows in the base game

Every base game spin plays on the bottom three rows with 243 ways to win. Ways to win pay for matching symbols on neighbouring reels from left to right, wherever they sit in each column, rather than along fixed lines.

The Phoenix Wild and the respin

When a Phoenix Wild lands, two things happen. It opens extra rows above the reels, and it triggers a respin. More rows mean more symbols in each column, which means more possible ways for a win to form on that respin.

Opening the whole grid: 8 free spins

If the respins open every row, the game moves into 8 free spins with the full grid in play and 7,776 ways to win. That is the round where the game's bigger results are most likely to come from, because every spin uses the largest possible grid.

1. A base spin plays on 5×3 with 243 ways.
2. A Phoenix Wild lands, opens extra rows and awards a respin.
3. The respin plays on the bigger grid, with more ways to win.
4. If the whole grid is opened, 8 free spins start on 7,776 ways.
5. If it isn't, play returns to the standard 5×3 grid.

Exactly how many rows each Phoenix Wild opens, and how the respin chain ends, is set out in the game's help screen. Read it once before playing for money.

Where 243 and 7,776 ways come from

Ways-to-win counts are simple multiplication. On a grid where every reel has the same height, multiply the number of rows by itself once for each reel.

So the free spins round offers 32 times as many ways as the base game (7,776 ÷ 243 = 32). More ways does not mean bigger wins on every spin, though: the game's maths is balanced so that the overall RTP stays at the published figure. For other games built on ways, see our Megaways guide and the Megaways glossary entry.

Phoenix Sun RTP on a £20 budget

Here is a useful way to think about cost. If you play exactly £20 through the game once, the average loss is the same whatever your stake: £20 × 3.92% = about 78p. What the stake changes is how many spins you get for that £20, and so how long the session lasts.

Wins are usually played back in, so total stakes in a session often run past your deposit, and the edge applies to every pound you stake. UK rules require at least 2.5 seconds per spin, which means no more than 1,440 spins an hour. At 10p, that ceiling is £144 staked an hour and an average cost of about £5.64. Medium volatility means actual results will swing either side.

Phoenix Sun on mobile: what to expect

A game whose grid can double in height needs vertical space. On a phone, the fully opened six-row grid is denser than the starting 5×3, so symbols get smaller. Whether the casino's build supports portrait mode isn't stated in the specifications we checked, so turn your phone to see which layout reads better.

Like other online slots, Phoenix Sun has no app of its own: it opens inside whichever casino app or mobile site carries it. Keep that casino app updated, especially on an older handset; our guide to casino apps on older phones explains why that matters.

Whether any of these apps carries Phoenix Sun is something to check in the app's game lobby. For setup help, see our page on casino apps on iPhone.

UK slot rules and the Phoenix Sun respin

Phoenix Sun follows the same Gambling Commission rules as every online slot played in Great Britain. A few interact with how this game feels.

• Stake caps: £5 a spin for players aged 25 and over since 9 April 2025, and £2 for those aged 18 to 24 since 21 May 2025, per the Commission's online slots stake limit guidance (opens in a new tab).
• Spin speed: at least 2.5 seconds between one game cycle and the next, with no turbo or slam-stop, under RTS 14 (opens in a new tab).
• No autoplay: each paid spin needs its own tap, in force since 31 October 2021.
• Honest celebrations: a return equal to or below your stake can't be dressed up as a win.
• Feature buys: since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players.

The respin a Phoenix Wild awards doesn't cost an extra stake; it belongs to the same paid spin. Our explainer on game speed rules on mobile and the page on UK game design rules cover the detail.
