Fatz’s Diner Slot Demo
Fatz’s Diner Slot Overview
Fatz’s Diner is Yggdrasil’s take on the classic American diner slot, and I liked how they pushed the theme beyond simple burgers and neon lights. You sit in a retro booth with a jukebox bobbing next to the reels, while a cast of animal high-school stereotypes runs the place. The comic art style, soft pastel reel frames, milkshakes and fries in the background, plus rockabilly music before rock and roll, all create a lively atmosphere.
Under the glossy surface, Fatz’s Diner is a 5-reel, 5-row video slot with 40 fixed paylines. I trigger spins on any device and pick stakes between 0.20 and 40 per spin, so it suits testing in demo mode as well as serious real-money play. Wins land when three to five matching symbols hit consecutive reels from the left, and the whole setup is built around the trademark Gigablox mechanic.

Symbols and Payouts in Fatz’s Diner
In Fatz’s Diner the paytable starts with food. Bananas, blueberries, a leafy green option and slices of meat form the lower-paying symbols, awarding up to around 0.8 times your stake for five of a kind. Above them sit the animal students: a crocodile in a suit, a geeky ape, a glamorous goat, the lion jock and Fatz the hippo manager, who can reach 4 times the bet for top hits.
There are nine standard paying symbols in total, plus special icons. The Wild is a vinyl record that substitutes for all regular symbols, while the shiny Bonus Scatter triggers free spins. Because Gigablox symbols split into several normal positions for payout, a single large Fatz block can turn into many high-value hippos on the grid, and I often see multiple win lines stacking up from one well-placed monster symbol.

Bonus Features in Fatz’s Diner
When I spin Fatz’s Diner, the Gigablox feature steals plenty of attention. On every spin, between two and five reels can merge into a single Gigablox reel, producing oversized symbols from 2x2 up to 5x5 in size. Before wins are calculated, those giants break into regular icons, so a big symbol often connects across many paylines. All symbols except the arrow Expand & Respin icon can appear as Gigablox blocks.
The Expand & Respin symbol behaves like a small engine for the grid. When it lands, you get an immediate respin and the current Gigablox area stretches by one reel towards the arrow. I have had spins where several arrows land together, giving a chain of respins and a larger block. If I want access to the feature, I can buy 10 to 30 free spins for 100x or 30 Super Spins with a x9 hippo multiplier for 600x.
Free spins in Fatz’s Diner arrive when five or more Bonus symbols hit anywhere. You start with 5 spins plus the number of triggering Scatters, so the feature usually opens on 10 to 30 spins. During the bonus, every three collected Expand & Respin icons increase the minimum Gigablox size, and the hippo becomes the star, starting with an x3 win multiplier that climbs by three whenever Fatz joins a winning combination and never resets.
How to Win in Fatz’s Diner Slot
I approach Fatz’s Diner like any high-volatility slot: set a stake I am comfortable with, then chase the features. Spins start with the main button on the right, and wins pay for three to five matching symbols on any of the 40 lines starting from reel one. I like using the demo first to see how often Gigablox and Expand & Respin show up, then tweak sound, spin speed and staking before risking real money.
Fatz’s Diner RTP, Volatility & Max Win
In terms of numbers, Fatz’s Diner runs on a default RTP of 96% with high volatility, which matches what I expect from Yggdrasil’s Gigablox releases. Some casinos use lower RTP settings of 94%, 90.5% or even 86%, so I always check the help screen. The maximum win sits around 9,000 times the stake, with one version quoting 9,052x, so the game has enough punch for serious bonus hunters.

Fatz’s Diner Slot Final Thoughts
After plenty of sessions, I see Fatz’s Diner as a confident mix of theme and mechanics. The animal cast, pastel reels and rockabilly soundtrack give the slot plenty of personality without getting in the way of the action. Gigablox works well on the square 5x5 grid, and when big hippo blocks line up with a growing multiplier, the screen feels packed with potential even on relatively modest stakes.
It is not a game for short bankrolls, because high volatility and the focus on free spins mean stretches of small wins while you chase the bonus. When it comes together, though, the Expand & Respin chains and scaling Gigablox reels make for tense moments. I would recommend Fatz’s Diner to players who enjoy feature-driven slots with buy options and who like a quirky diner theme instead of dark fantasy.
