Fat Santa slot at a glance
Fat Santa came out in 2018 from Push Gaming, the London-based studio better known for Jammin’ Jars and Big Bamboo. It uses a square 5×5 grid with 50 fixed paylines, which gives a growing wild plenty of room to spread.

How the features work in Fat Santa
Fat Santa has one base-game feature and one bonus round. Both rely on mince pie wilds, which is the thread that ties the game together.
Santa’s Sleigh
At random during the base game, Santa’s Sleigh can trigger and drop mince pie wilds onto the reels. Those wilds lock in place while the reels respin, so the respin is played with extra wilds already fixed on the grid. Because it is random, there is nothing you can do to make it appear.
Free games and the growing Santa
Free games start when a Santa wild lands on the same spin as a mince pie wild. You begin with 5 free spins. Santa then becomes a moving wild that eats mince pies as they land. Eating pies makes him bigger, starting at 1×1 and growing up to a full 5×5, and each increase in size adds extra spins.
In practice, the round has two aims at once: Santa needs pies to grow, and each size increase extends the round. A big Santa covering much of the 5×5 grid acts as a wild across many of the 50 lines at the same time.
| Base game | Free games | |
|---|---|---|
| Special event | Santa’s Sleigh (random) | Moving Santa wild |
| Role of mince pies | Dropped as wilds that lock during a respin | Eaten by Santa so he can grow |
| How it starts | Randomly on any spin | Santa wild plus mince pie wild on one spin |
| Length | One respin | 5 spins, plus extra spins as Santa grows |
| Largest wild | Individual mince pie wilds | Santa at up to 5×5 |
Fat Santa RTP: 96.45% or 94.15%?
Push Gaming supplies Fat Santa at two RTP settings. The game looks and plays identically; only the long-run return changes. That makes it worth a minute to check before you play, because no amount of in-game choice changes the house edge.
| Stake | Staked over 100 spins | Expected cost at 96.45% | Expected cost at 94.15% |
|---|---|---|---|
| 10p | £10 | £0.36 | £0.59 |
| 50p | £50 | £1.78 | £2.93 |
| £1 | £100 | £3.55 | £5.85 |
Figures are rounded to the nearest penny. They come from stake × house edge, which is standard game maths rather than a prediction for any one session.
- Open Fat Santa in your casino app.
- Tap the game’s information or help button, often shown as “i” or a menu icon.
- Find the line on return to player (RTP) or theoretical return.
- Check whether it shows 96.45% or 94.15%.
- If no figure is shown, ask the casino’s customer support which version it runs.
Fat Santa volatility on a £20 budget
Medium to high volatility puts Fat Santa between steady and swingy. Results will be uneven, but not as extreme as the highest-volatility games in our reviews. A £20 budget gives 200 spins at 10p, 40 at 50p or 20 at £1 if nothing came back, and in reality small returns stretch it a little further.
The random Sleigh feature helps fill the gaps between free games, but most of the game’s value still sits in the bonus round. At higher stakes, a run without free games can use up a budget before the round arrives. Lower stakes give more chances at it for the same money, though the expected cost per pound staked is unchanged.
Gambling is entertainment that costs money, and the house edge means losses are likely over time. If you are setting money aside for Christmas, keep any gambling budget separate and small. Our page on budgeting for casino apps has practical ideas.
Playing the Fat Santa slot on your phone
Fat Santa is an HTML5 game, so it runs inside casino apps and mobile browsers without a separate download. Push Gaming does not state whether it is built for portrait or landscape. On a 5×5 grid, symbols are smaller than on a 5×3 game, so a larger phone or tablet makes the mince pies and Santa’s growth easier to follow.
- Stick to the official app stores for casino apps. Our iPhone download guide shows how to check the publisher.
- Search the lobby for “Fat Santa”; we cannot confirm which apps stock it.
- Open the paytable to see symbol values; no maximum win figure is published.
- If your connection drops during free games, the casino’s server holds the result. See what happens if your app crashes mid-game.
If seasonal marketing messages are unwelcome, our guide to turning off casino app notifications explains how to switch them off on iPhone and Android.
UK rules for the Fat Santa slot
British versions of Fat Santa run under rules introduced after the game launched. The main ones come from the Commission’s responsible product design standard (opens in a new tab) and its online slots stake limit guidance (opens in a new tab).
- Maximum stake of £5 per spin if you are 25 or over, and £2 if you are 18–24. More on our slot stake limits page.
- At least 2.5 seconds per spin, with no autoplay, turbo or slam-stop.
- No celebrating a return that is equal to or less than your stake.
- Your net spend and time played shown as you play.
- Credit cards cannot be used to gamble, including via e-wallets funded by a credit card.
Fat Santa vs Fat Rabbit and Fat Banker
Push Gaming has several games with “Fat” in the name. Their published figures show how they differ.
| Slot | RTP | Volatility | Layout | Max win |
|---|---|---|---|---|
| Fat Santa | 96.45% (94.15% version) | Medium to high | 5 × 5, 50 lines | Not published |
| Fat Rabbit | 96.45% (94.15% version) | High | 5 × 5, 50 lines | Not published |
| Fat Banker | 96.43% (94.45% version) | High | 6 × 6, 50 lines | 25,000× stake |
Fat Rabbit shares the grid, line count and RTP settings but is rated higher volatility. Fat Banker uses a larger grid and publishes a 25,000× ceiling. Fat Santa is the gentlest of the three on paper.
Other Christmas slots to play on mobile
If you want another seasonal game, Big Bass Christmas Bash from Reel Kingdom has a 96.71% RTP, high volatility and 10 fixed paylines on a 5×3 grid. It belongs to Reel Kingdom’s Big Bass series and plays very differently from a growing-wild game.

Frequently asked questions
What is the RTP of Fat Santa?
Fat Santa’s RTP is 96.45%, and a 94.15% version also exists. The casino chooses which to offer, so your app may run either one. On £100 staked, the expected cost is £3.55 on the higher version and £5.85 on the lower. Open the game’s information screen to check the figure before playing. Our guide to finding a game’s RTP in an app explains where to look.
How do you trigger free games in Fat Santa?
You trigger free games when a Santa wild lands on the same spin as a mince pie wild. The round starts with 5 free spins. Santa then moves around the grid and eats mince pies to grow from 1×1 up to 5×5, and each increase in size adds extra spins. Free games cannot be bought in UK apps. Our guide to free spins in casino apps explains how in-game rounds differ from bonus spins.
What does Santa’s Sleigh do in Fat Santa?
Santa’s Sleigh is a random base-game feature. When it appears, it drops mince pie wilds onto the reels, and those wilds lock in place while the reels respin. It can happen on any spin, and nothing you do changes the chance of it appearing. It adds variety between free games, though most of the game’s value still sits in the bonus round. Our page on slots on mobile covers common slot features.
Is Fat Santa high volatility?
Fat Santa is rated medium to high volatility, which is a step below the highest-volatility slots. Expect uneven results, with longer quiet spells between free games, but fewer extreme swings than games such as Fat Rabbit, which is rated high. Volatility does not change the house edge. Lower stakes simply give you more spins for the same budget. Our volatility explainer puts the ratings side by side.
What is the max win on Fat Santa?
A maximum win figure for Fat Santa is not published by Push Gaming in a form we could confirm, so we do not quote one. The paytable and rules screen in the game show symbol values and any cap that applies. Remember that a maximum win is a rare ceiling and that the house edge makes losses the likely outcome over time. See our Push Gaming page for the studio’s other published figures.
Can I play Fat Santa on my phone?
Yes, Fat Santa is an HTML5 slot that runs in casino apps and mobile browsers on iPhone, iPad and Android, if the casino offers it. Its 5×5 grid means smaller symbols, so a larger screen can help. You must be verified as 18 or over before playing, even in demo mode. Install apps only from official stores; our Android install guide shows how to find the genuine listing.
Is Fat Santa only available at Christmas?
No, nothing in Fat Santa’s published details limits it to one season. It is a 2018 slot, and whether and when an app lists it is up to each casino, so search the lobby by name. Seasonal promotions still come with terms, and any gambling budget should be separate from money set aside for the holidays. Our Christmas slot alternative review covers another festive game.
What is the difference between Fat Santa and Fat Rabbit?
The main published difference is volatility. Both are Push Gaming games on a 5×5 grid with 50 fixed paylines and the same two RTP settings, 96.45% and 94.15%. Fat Santa is rated medium to high volatility, while Fat Rabbit is rated high, so Fat Rabbit should swing more. Neither has a published maximum win.
