Order up! It's time to step back to the 50s with Yggdrasil Gaming. The destination? A funky themed diner owned by a hippo aptly named Fatz. Combining classic style with incredible food, Fatz is here to satisfy your appetite with big potential and big reels – Gigablox reels, to be specific.
Turn on the jukebox, and get ready to be served some delicious treats, because Yggdrasil are mixing exotic animals with flavoured features and spicy wins in Fatz's Diner Gigablox.
With RTP options up to 96.0%, this highly volatile release can produce wins up to 9,052x.

If you look up '50's diner' in the dictionary, you'll get this picture. From the bright pink walls to the turqoise leather furniture, everything in Fatz's Diner looks vintage. Black and white checkered tiles, prints on the walls, and the flashing tail lights of a classic car all help this spot feel friendly. To the left of the reels sits a jukebox just waiting for a tune to be picked, whilst some tasty food and milkshakes sit to the right.
On the reels we meet the exotic animals we were promised – and they weren't lying. Suited and booted gators, leather clad lions, pink reindeers, geeky monkeys and of course Fatz himself all bring some fun to the reels, coupled with images of food and record Wilds. It's all finished off with a swinging, upbeat soundtrack to tie it all together.

Fatz's Diner Gigablox Base Features
Taking place across 5 reels, wins are formed on Fatz's Diner Gigablox by matching at least 3 symbols on adjacent reels, beginning with the leftmost reel, across 1 of 40 fixed win lines. Symbols available begin with non premiums, with bananas, blueberries, salad and meat. Land between 3 and 5 of a kind of any non premium to see wins between 0.20 and 0.80x bet.
At the premium end we meet the animals – alligators, monkeys, reindeer, lions and hippos. Land 3 of a kind of any premium to see wins between 0.30 and 0.60x bet, increasing to values between 1 and 4x bet for 5 of a kind matches. Finally, record Wild symbols are available and substitute for all symbols except Bonus Scatter symbols or Expand & Respin symbols.

Gigablox
There are a few things to cover in Fatz's Diner Gigablox, beginning with the actual Gigablox mechanic itself. On each spin, between 2 and 5 reels can merge to form a colossal Gigablox reel.
Gigablox reels can be 2×2, 3×3, 4×4 or 5×5. After they have landed Gigablox symbols will break down into the same symbol of a smaller size to pay wins. All symbols except Expand & Respin symbols can land as Gigablox.
At least 1 Gigablox reel will land per spin.

Expand & Respin
The next thing to cover is the Expand & Respin feature, triggered by landing an Expand & Respin symbol. A maximum of 1 of these symbols can land per reel and they cannot land on a Gigablox reel.
If at least 1 Expand & Respin symbol lands on the reels a respin will be awarded. During the respin, the Gigablox reel in view will expand by 1 reel in the direction of the Expand & Respin symbol.
If more than 1 Expand & Respin symbol lands on the reels, the Gigablox reel will be expanded by multiple reels. If Expand & Respin symbols appear on both sides of the Gigablox reel, it will expand in both directions.
If another Expand & Respin symbol lands during the respin, a further respin is awarded with the Gigablox reel expanded once more. Respins continue until no new Expand & Respin symbols land.

Fatz's Diner Gigablox Bonus
Land 5 or more Bonus symbols to trigger Free Spins. The number of spins awarded is 5 plus 1 for each Bonus symbol in view.
During Free Spins, each Expand & Respin symbol that lands in view is collected. Once 3 have been collected, the minimum GigaReel size is increased for each remaining spin.
- Collect 3 Expand & Respin symbols – minimum size 3×3
- Collect 6 Expand & Respin symbols – minimum size 4×4
- Collect 9 Expand & Respin symbols – minimum size 5×5

Hippo Multiplier
Additionally, a multiplier is active on the highest paying symbol – Fatz the Hippo – during Free Spins.
This multiplier begins at x3 and increases by +3 each time a win occurs involving Hippo symbols. The multiplier does not reset between spins.
Land Bonus symbols during Free Spins to trigger an additional +1 spins per Bonus symbol.

Buy Bonus
Players in appropriate regions can take advantage of two Buy Bonus options.
- 10-30 Free Spins – 100x bet
- 30 Super Free Spins – 600x bet
During Super Free Spins the Hippo multiplier begins at x9.
The maximum win available in Fatz's Diner Gigablox is 9,052x bet. If the sum of a single game round exceeds this, the game round will end and 9,052x bet will be awarded.

First Impression
There's plenty happening in Fatz's Diner Gigablox – between and bold and fun theme, Gigablox, respins, and increasing multipliers, there's more than enough to keep the average player entertained.
In the base game, Expand & Respins symbols coupled with Gigablox Reels carry the heavy load, helping to keep things ticking over until Free Spins are triggered. When Free Spins are triggered, increasing minimum reel sizes and Hippo multipliers create a sense of excitement.
Of course, win values are significantly lower to account for Gigablox so it often feels like there are lots of small wins and none that are truly huge, but there's still enough to keep you interested for a while – especially in Super Free Spins. When the right combinations land, wins are possible up to 9,052x bet.
Finally, maths is highly volatile and RTP options are available up to 96.0%, so no complaints there. If you're a fan of Gigablox and fancy something bright and fun, Fatz's Diner Gigablox could suit you.
