You’re taken into a typical 1950s-inspired American diner in Fatz’s Diner, but what’s not so typical is the fact that it’s run by a hippo. Both the jukebox and the food plates on the desk jump whenever you land a win, which is a bit strange and perhaps also annoying for some players. Looking past these minor details, however, Fatz’s Diner slot is a refreshing installment in theGigablox genre. It comes with an innovative feature that brings the series forward, something that’s been long overdue.
The anthropomorphic animals are charming enough, but the Expand & Respin feature steals the show in this game. It will expand the gigablox symbol for a respin of the remaining symbols, and this can happen up to multiple times leading to a full-screen win. The bonus round is all about persistently upgrading the Gigablox symbols that land on every spin, as well as the top-tier Hippo symbol multiplier. This is how you can close in on the 9,000x potential, but keep in mind that the symbol values are pretty low in this game.
Yggdrasilis a veteran developer that’s been around since 2013. They have won multiple prestigious awards over the years, and they have released 135 video slots including the one at hand. They are known for popular series likeVikings Go Wild, as well as the DoubleMax multiplier range. Of course, they are also the inventors of the Gigablox system.
This typical, yet strange, American diner is frequented by carnivores and vegans alike it seems, and even gangster types hang around here for some reason. They serve blueberries, bananas, salads, and a massive ham, as well as burgers and milkshakes. The 1950s nostalgia is running strong all the way, and the jukebox is rocking it to its own tunes there on the left-hand side.
The Fatz’s Diner RTP of96.05 %is about as average as it gets. However, operators can adjust the RTP down to94, 90.5, or 86 %, depending on the market. This is a high volatility release from Yggdrasil, so you can expect significant ups and downs on your bankroll in longer sessions. The Fatz’s Diner max win is9,000x your stake, which is pretty solid even for this volatility level.
You can play Fatz’s Diner slot with bet levels between £0.2 and £40 per spin, which is a fairly average bet range that most player types should be able to work with. You win by landing 3 to 5 matching symbols across at least 1 of the 40 paylines, and vinyl record Wild symbols step in for any pay symbol to help you out in that regard.
You get Gigablox on every spin in all stages of the game, as is usually the case with this feature. The unusual twist in this game is the Expand & Respin symbol/feature, as well as being able to persistently grow the Gigablox in the bonus round.
You get Gigablox symbols on every spin, and they come insizes 2×2, 3×3, 4×4, and 5×5. This means that you can land a full grid Gigablox symbol, and Gigablox counts as regular 1×1-sized symbols when part of a win. Wilds and Scatters can land as Gigablox symbols as well, but not the Expand & Respin symbol (see below).
The Expand & Respin symbol triggers a free respin when it lands, and the current Gigablox symbol will then expand 1 position towards the Expand & Respin symbol. You can land additional Expand & Respin symbols to continue the respins feature, and the Gigablox expands per symbol you land.
You need5+ bonus scatter symbolsin view to trigger the Fatz’s Diner Bonus Round. You get5 free spinsplus the number of triggering scatters. This means that 5 scatters award 10 free spins, while a screen full of scatters awards 30 free spins.
The Expand & Respin symbols are collected in a meter during the bonus round, and every 3 you collect increases the minimum Gigablox size. Collect 3 to get to a minimum size of 3×3, land 3 more to get size 4×4+, and 3 on top of that to get full-grid 5×5 Gigablox per free spin.
Landing wins with the top-tier Fatz the Hippo symbol increases the win multiplier for that symbol. The multiplier is on display up to the right, and it starts at x3. The multiplier increases by +3 for every Fatz the Hippo win, and it never resets for as long as the bonus round lasts. Finally, you win +1 extra free spin per scatter that lands in the bonus round.
Eligible players get 2 options in the Fatz’s Diner bonus buy menu. You can pay 100x the stake to get between 10 and 30 free spins from the triggering spin, or you can pay600x the staketo get 30 super free spins with an x9 starting Fatz the Hippo multiplier.
You get to see a few base game wins here and there before we purchase the Super Free Spins round at 0:48 into the 5:18-minute highlights video. We managed to get to the 4×4-size Gigablox level after a while, and you can see how we fared by hitting the play button below.
Fatz’s Diner slot doesn’t really sound like the place you go for a plate of blueberries, and the menu is a strange mix of burgers, ham, and more healthy food items. Nonetheless, this is definitely a diner you want to visit if you’re a fan of the Gigablox series, and even perhaps also if you’re not a huge fan from before. Some of the previous installments, not to say many of them, ride too much on the Gigablox mechanic alone in the base game. This is not the case here, however, thanks to the brand new and innovative Expand & Respin feature.
Being able to grow the gigablox for consecutive wins is a welcome addition, but the low overall symbol value will sometimes lead to disappointing results as well. A full-screen win with the top-tier Hippo awards only 140x the stake in the base game. The bonus round is therefore needed for larger payouts, which is most likely to come from the multiplier-upgradable hippo symbol. Tension will rise when you get 4×4 gigablox per spin and beyond, but upgrading the hippo multiplier was harder than leveling up the gigablox size. Overall, Fatz’s Diner game is a solid installment in the series, but a bit more fine-tuning could’ve made it even better.

Increasing the hippo multiplier is therefore crucial when it comes to closing in on the Fatz’s Diner max win of 9,000x your stake.
