Phat Cats Megaways Review
Kalamba has a thing for cats it seems, and Phat Cats Megaways takes you to Las Vegas in what amounts to a somewhat unusual dynamic grid release. The base game plays out in the office of the big boss (an anthropomorphic tiger), and his cigar is smoldering in the ashtray. You can get up to 200,704 ways to win via the dynamic grid, and the top tracker reel has a few tricks up its sleeve.
The cats in this game are not as cute as what we’ve seen before from this developer, and the math model means business as well. The defining feature is the Mystery stacks that appear in all stages of the game, and they can deliver cash coin prizes up to 1,000x per symbol. The multiplier increases per bonus round spin, and the feature goes on as long as mystery stacks are present.

Phat Cats Megaways Slot Features
The Big Boss symbol pays also for 2 of a kind, while the rest of the symbols pay for 3 to 6 of a kind wins. The premium symbols award between 0.75 and 3 x your stake for 6 of a kind, and the Wild symbol steps in for pay symbols to help complete wins.
Mystery Symbols land in stacks, and they turn into a random matching pay symbol per spin. They can also turn into Coin symbols, and the mystery stacks nudge one step down per spin that follows. This locks the number of positions on the Megaways grid per spin, and mystery symbols are saved between bet levels. The Coin symbols reveal random multiplier values up to x1,000, and these are summed to to pay as a bet multiplier.
The top horizontal tracker reel can slide in Upgrade and Lock Symbols, and the Upgrade Symbols lock symbols on the vertical reels below in addition to adding +1 row for the next spin. Lock Symbols simply lock symbols on the reel or reels below for the next spin.
You need 3+ scatters in view to trigger the Bonus Round, and you start out with 4 mystery symbols on reels 2 and 5. You can land more mystery symbols organically as well, and the free spins go on as long as you have at least 1 mystery symbol in view. The overall win multiplier increases by +1 after each free spin, and it boosts all wins. Non-UK players, and anyone eligible, can purchase the bonus round for 149x the stake.
The 200 Spins Phat Cats Megaways Slot Experience
Nothing too exciting happened for us in the base game, but at least you get a brief taste of it before we purchase the bonus round. This happens around 0:48 into the 2:14-minute highlights video, and you can see for yourself how we fared by hitting the play button below.
Review Summary
We like the somewhat unusual Vegas presentation in Phat Cats Megaways, but the grid is a bit small for a Megaways release. It makes it harder to appreciate the artwork, but then again, you get to appreciate the background office in the base game and the Vegas neon signs in the bonus round. Both are well-made and pleasant visuals, and featurewise this is solid stuff as well.
Admittedly, Kalamba seems to have taken a page from Push Gaming’s Razor Shark, but the stacked mystery symbols can deliver solid payouts out of the blue nonetheless. The Coin wins can be quite decent as well, and everything is taken up a notch when the multiplier increases per spin in the bonus round. The feature can be short-lived many times, but when things go your way up to 20,000x your stake is possible.
Pros
- Mystery Stacks turn into symbols or coins
- Coin bet multiplier prizes up to x1,000
- Indefinite FS w/ increasing multiplier
- Win up to 20,000x your stake
Cons
- Beware of customizable RTP ranges
