Fatz’s Diner - Slot Review

Fatz’s Diner Gigablox slot is played on a grid of 5×5 reels and 40 paylines. Its 96% RTP is coupled with high volatility and a winning potential of up to 9,000x the stake. The Gigablox mechanism is present, as are an Expand & Respin function and Free Spins with an option to buy. To take advantage of this playful and lucrative atmosphere, it will cost you between $0.20 and $40 per spin.

Once you’ve placed your bet, regular winnings are awarded from left to right, starting with the reel furthest to the left. You’ll need to align 3 to 5 identical symbols to win. As weak symbols, the banana regiment, blueberries, flower salad or ham leg pay between 0.20x and 0.80x the stake. The crocodile, monkey, goat, lion and hippopotamus pay between 0.30x and 4x the stake as strong symbols of Fatz’s Diner Gigablox. There’s also the Vinyl record, a wild symbol that replaces all other regular symbols.

With each spin, between 2 and 5 reels can merge to form a colossal Gigablox reel featuring oversized symbols that function as individual symbols spanning 2×2 to 5×5 positions.

Expand & Respin

When the Expand & Respin symbol appears, a respin is triggered and the Gigareel expands by one reel to display only gigantic symbols. Multiple Expand & Respin symbols can appear to produce several additional respins.

Free Spins

Find 5 or more bonus symbols to trigger Free Spins. The number of free spins won is a minimum of 5, and each bonus symbol earns an additional free spin. For every three Expand & Respin symbols collected during Free Spins, the minimum Gigareel size increases for the remainder of the Free Spins. In addition, a multiplier applies to the strongest hippo symbol. This multiplier starts at x3 and increases by +3 each time the hippo contributes to a winning combination. You can win additional free spins with new bonus symbols.

The Expand & Respin mechanism on the Gigablox reels is an interesting feature that we were able to experience on several occasions during our trial, and despite the somewhat low payouts, the maximum winning potential remains high with a value of 9000x the stake.
