What is Fat Cats DoubleMax?

Fat Cats DoubleMax centres on stylish feline characters in a luxurious setting, combined with a 5×5 grid and several familiar Yggdrasil mechanics. After winning combinations, symbols disappear through cascades and new symbols drop into place to create further winning opportunities.

The DoubleMax™ multiplier increases throughout consecutive cascades, while Gigablox™ can place oversized 2×2 or 3×3 symbols on the reels. Golden Claw, Paw Slap and Champagne can also alter the grid or multiplier during the base game.

Symbols

The higher-value symbols are different richly dressed cats, each with its own visual style. The lower-value symbols are the card ranks A, K, Q, J and 10.

The Wild substitutes for all regular symbols except the Bonus symbol. A combination made entirely from Wilds does not produce a payline win.

The Bonus symbol triggers the Free Spins when 3 or more appear in view. Bonus symbols do not need to land on a payline and are evaluated only after all cascades from the spin have finished.

Cascades

After each winning combination, the involved symbols are removed from the reels. New symbols then drop into the empty positions, creating another chance for winning combinations within the same spin.

After every cascade, a Wild is also added to a random position before the remaining empty spaces are filled. A newly added Wild can replace an existing Wild, but it cannot replace a Bonus symbol.

The cascade sequence continues for as long as new wins are formed. Once no further winning combination appears, the sequence ends.

DoubleMax™

DoubleMax™ is directly linked to the cascades. Every new cascade doubles the total win multiplier.

The multiplier begins at 1× and can then rise through 2×, 4×, 8×, 16×, 32×, 64×, 128×, 256×, 512×, 1,024×, 2,048×, 4,096× and 8,192× up to a maximum of 16,384×.

In the base game, the multiplier resets after a spin or cascade sequence ends without another win. During Free Spins, it works differently: the accumulated multiplier carries over between individual spins.

Gigablox™

Gigablox™ are oversized symbols that occupy multiple positions at the same time. They can appear in 2×2 or 3×3 formations and function as the same symbol across those positions for win calculations.

Bonus symbols can also appear within a Gigablox formation. When this happens, multiple Bonus symbols are arranged within a single-symbol-high section of the oversized block.

Gigablox™ works together with cascades and DoubleMax™, allowing large symbols to become part of consecutive winning combinations.

Golden Claw Bonus

Golden Claw can activate randomly after a losing spin. The golden claw scratches across 2 or 3 adjacent standard reels and merges them into one large Giga Reel.

This Giga Reel first shifts to the left-most position to create another chance of a win. During subsequent symbol drops, the large reel then moves back to the right one position at a time while the feature continues.

Wilds can be added during Golden Claw and new symbols can drop into place, creating multiple additional opportunities for wins. Golden Claw does not appear during Free Spins.

Paw Slap Bonus

Paw Slap can activate during the base game when a mouse appears on the multiplier trail. A cat's paw then removes one or more steps from the trail, increasing the starting multiplier for that spin.

The starting position can be increased by 1 to 5 steps, with a maximum starting multiplier of 32×. From that higher starting point, DoubleMax™ continues to increase normally during any cascades.

Paw Slap applies only to the relevant spin and does not appear during Free Spins.

Champagne Bonus

Champagne can activate after a losing spin. A Fat Cat appears above a random reel and pours champagne down the entire reel.

All symbols on that reel are then changed into the same matching symbol, creating another opportunity for a winning combination.

Unlike Golden Claw and Paw Slap, Champagne can appear in both the base game and Free Spins. It does not activate on spins where Giga Reels are already in play.

Free Spins

Free Spins are triggered when 3 or more Bonus symbols appear in view. Three Bonus symbols award 7 Free Spins, four Bonus symbols award 10 Free Spins and five Bonus symbols award 15 Free Spins.

During the feature, the DoubleMax™ multiplier carries over between individual spins. Where the multiplier resets after a completed cascade sequence in the base game, it can continue building throughout the Free Spins. Cascades, added Wilds and Gigablox™ also remain active.

Golden Claw and Paw Slap do not appear during Free Spins. Champagne can still activate. The Free Spins cannot be retriggered.

Golden Bet

Fat Cats DoubleMax includes an optional Golden Bet that doubles the chance of triggering the Free Spins.

Golden Bet increases the stake by 30% and can only be activated in the base game. Any wins are still calculated from the regular base stake.

Maximum win

The maximum win in Fat Cats DoubleMax is 10,000× the stake.

Although the DoubleMax™ multiplier can rise as high as 16,384× during cascades, the maximum total win of the video slot remains capped at 10,000× the stake.

Why Fat Cats DoubleMax stands out

Fat Cats DoubleMax brings together several mechanics that directly interact with one another. Cascades create new winning opportunities, each cascade doubles the DoubleMax™ multiplier and a Wild is also added to the grid after every winning cascade.

Gigablox™ adds oversized 2×2 and 3×3 symbols, while Golden Claw, Paw Slap and Champagne alter the base game in different ways. Golden Claw creates a temporary Giga Reel, Paw Slap boosts the starting multiplier and Champagne changes an entire reel into matching symbols.

DoubleMax™ becomes especially important during the Free Spins because the multiplier carries over between spins. This allows consecutive Free Spins to keep building on the same multiplier trail.

Is Fat Cats DoubleMax worth playing?

Fat Cats DoubleMax is mainly suited to players who enjoy cascades, rising multipliers and bonus mechanics that can strengthen one another within the same spin. The combination of DoubleMax™, Gigablox™ and three different modifiers adds plenty of variation to the 5×5 grid.

This Reflex Gaming release via Yggdrasil Gati combines 50 paylines, Free Spins with a persistent multiplier and a maximum win of 10,000× the stake.
