Fat Rabbit slot review

Fat Rabbit slot: summary for app players

Fat Rabbit is one of the earlier hits from Push Gaming, the London-based studio founded in 2010. It came out in 2018 and uses a square 5×5 grid with 50 fixed paylines, so every line is always active and your stake covers all of them.

The rabbit-and-carrots theme hides a high-volatility game. Two features do most of the work: a random Harvest in the base game and a free games round where a rabbit wild grows by eating carrots. There is no published fixed maximum win.

How the features work in Fat Rabbit

The Harvest feature

On any base-game spin, the Harvest feature can trigger at random. When it does, carrot wilds are added to the grid. The positions that aren’t holding those carrots then respin, giving the new symbols a chance to line up with the wilds already in place.

Because it is random, there is nothing you can do to make Harvest more likely. Outcomes on UK-licensed slots come from a random number generator that the Gambling Commission’s standard on random outcomes (opens in a new tab) covers, so timing, stake changes and patterns don’t help.

Starting the free games

The free games begin when a rabbit wild lands on the grid together with a carrot. The round starts with 5 free spins.

The growing rabbit

During the free games, the rabbit is a wild that moves around the grid. Each time it eats carrots it grows, starting at 1x1 and getting larger up to a maximum of 5x5, which is the full size of the grid. Every time the rabbit increases in size, you get extra free spins, so growth both widens the wild and lengthens the round.

A big rabbit covers many positions at once, and with 50 fixed lines that can connect a lot of wins in a single spin. How far the rabbit grows varies from round to round, and that spread is a big part of why the game is rated high volatility.

The number of carrots needed for each size, the extra spins per increase and the symbol payouts are set out in the game’s paytable. Read it in your app, as we only describe what the developer’s feature summary states.

Fat Rabbit wild sizes on the 5×5 grid

It helps to picture what the rabbit covers at each end of its growth. The grid has 25 positions (5 × 5), and the wild starts on just one of them.

At full size the rabbit fills the whole 5×5 grid, so every one of the 50 lines would be made of wilds. The in-game rules explain how such a spin pays and how sizes in between are reached.

Fat Rabbit RTP: 96.45% vs 94.15% in pounds per hour

Push Gaming supplies Fat Rabbit in more than one RTP setting, and the casino picks which you get. The 96.45% version has a 3.55% house edge; the 94.15% version has 5.85%. Since nothing on screen changes between them, the help screen is the only place to tell.

The table shows the average hourly cost if you spun at the fastest pace UK rules allow, 1,440 spins an hour (one every 2.5 seconds). Slower play costs proportionally less.

These are averages over very long play. A single hour on a high-volatility game can go far better or far worse. The difference column is the part you control: choosing an app that runs the higher version reduces the average cost without changing the game.

Planning a £20 Fat Rabbit session on your phone

A £20 budget gives you 200 spins at 10p, 40 at 50p or 20 at £1 before any returns. On a game where the main value sits in a growing-wild bonus, the number of spins matters, so lower stakes usually suit a small pot better.

1. Decide your total budget and session length before opening the app.
2. Set a deposit limit to match; our guide to deposit limits explains the options.
3. Open Fat Rabbit and check the RTP in the help screen; if it reads 94.15%, consider whether another app runs the higher version.
4. Choose a stake that gives you a sensible number of spins: 10p turns £20 into 200 spins.
5. Watch the net spend and time display your app must show, and stop when you reach your limit, whatever the last spin did.

Playing the Fat Rabbit slot on iPhone and Android

Fat Rabbit opens inside licensed casino apps and mobile browsers from the slot lobby; it isn’t a separate download in the App Store or Google Play.

A square 5×5 grid is a better fit for a tall phone screen than a wide 5×3 game, since it doesn’t need as much width. The developer doesn’t publish orientation details for Fat Rabbit, so check how it displays on your own device and use whichever view keeps symbols readable.

A free games round gains spins as the rabbit grows, so its length isn’t fixed. Allow for that when you plan how long a session will last, and remember the base game runs at no faster than one spin every 2.5 seconds.

Fat Rabbit slot review: is it worth a spin?

Fat Rabbit is a well-designed high-volatility game with one memorable idea: a wild that grows as the round goes on. It suits players who enjoy a bonus round with visible progress and who can keep stakes low enough to reach it.
