Cats Slot Review: IGT’s Safari Feline Adventure

IGT, formerly trading as International Game Technology and using the WagerWorks brand for parts of its digital catalog, built Cats around a familiar structure with one twist. The base layout is a standard 5 reels and 3 rows with 30 paylines, numbers any regular slots player will recognize. The Split Symbols feature bends that structure by allowing a single tile to be read as two separate cats, which opens the door to combinations of up to 10 matching symbols on a line that normally tops out at five. That is the hook, and it is why the game has aged better than most releases from its era. For a broader look at how titles like this fit into the wider market, see the BestSlotsUSA homepage.

Cats sits in the medium volatility band, which means the reels tend to feed players a mix of small and mid-sized wins rather than long droughts punctuated by huge hits. Its published return to player figure of 94.93 percent is a little below the modern online average of roughly 96 percent, a reflection of the game’s age and its origins as a land-based product. It remains popular because the theme is approachable, the Split Symbols mechanic is genuinely different, and the free spins round can chain split cats into oversized wins. The sections below break down every spec, the symbols, the bonus and where the game is legal to play online in the United States.

Cats Version Comparison

Cats is a single title rather than a sprawling franchise, so the comparison below covers the two forms of the same game: the original casino-floor cabinet and the online adaptation that regulated US operators now carry. The specs are effectively identical because the online release is a faithful port of the physical machine.

Game Overview and How It Plays

Cats is a video slot built on a 5-reel, 3-row grid with 30 paylines. Players can trim the number of active lines down from 30 to as few as one, choosing among 1, 3, 5, 9, 15 or 30 lines, though playing all 30 is the standard approach because it keeps every winning pattern live. The line stake runs from 0.01 up to a high ceiling, so the minimum spin costs 0.30 with all lines active and the maximum climbs into the hundreds depending on the operator’s configuration. That spread makes the game workable for penny players and higher-stakes bettors alike.

The theme is a straightforward African safari. The reels are set against a plains backdrop, and the premium symbols are big cats: black panthers, leopards, cheetahs, jaguars and lions, joined by the standard playing-card royals for the lower-value spots. What makes the spins feel different from a normal safari slot is the Split Symbols system. Each cat can land as a single or as a double, and when a double lands it counts as two of that cat stacked in one reel position. Because a five-reel line can therefore register up to 10 matching cats, wins stack in a way that a conventional 5-of-a-kind game cannot reproduce. If you are new to reading paylines and return figures, the guides on RTP and how to play slots are useful primers.

Gameplay is deliberately simple to operate. There is a spin button, a bet selector, a line selector and an autoplay function. There is no bonus buy, no gamble ladder and no side bet, which keeps the focus on the base spins and the free spins round. The medium volatility means the base game hands out regular small returns, with the bigger payouts arriving when split cats align or when the free spins trigger. It is a low-friction game that rewards patience rather than a feature-hunting frenzy.

The hit frequency is reported at around 30 percent, meaning roughly one spin in three returns something, which is high for a slot with a five-figure top multiplier. That combination of frequent small wins and a rare large ceiling is the textbook profile of a medium-volatility game, and it is why Cats feels forgiving through a session even though its top prize is large. Players who want to understand how that balance affects bankroll life will find the primer on slot volatility useful, and those weighing this title against harder-hitting alternatives can compare it with the high volatility slots list. Because the published return of 94.93 percent trails the modern average, Cats will not appear among the highest RTP slots; its appeal is the Split Symbols mechanic rather than a market-leading payback figure.

Understanding Split Symbols

Split Symbols is the single feature that defines Cats and the reason the game has stayed in lobbies for more than a decade. On a normal 5-reel slot, a payline can register at most five matching symbols because there are five reels. Cats breaks that ceiling by letting any symbol land in one of two states, single or double. A single tile shows one cat and counts as one. A double tile shows two of the same cat stacked in that reel position and counts as two toward the line. When doubles land across several reels, a payline that physically spans five positions can register six, seven, eight, nine or even 10 matching cats, and the paytable rewards those longer combinations accordingly.

The mechanic is not limited to the premium cats. The Cats logo wild can land as a double, so one wild position can stand in for two wilds, and the paw-print scatter can also split, which is why five visible scatters can satisfy a trigger that would otherwise demand more icons. There is no multiplier attached to the split itself; the value comes purely from extending the length of a winning combination and from the way those extended combinations stack up during the doubled free spins. This is the same underlying idea IGT used in stablemates such as White Orchid, and it remains one of the more distinctive base-game mechanics in the studio’s library.

Symbols and What They Pay

The paytable is led by the big cats and rounded out by playing-card values. IGT does not publish a single official coin-for-coin paytable for the online release, so the figures below are drawn from independent reviews and describe relative ranking rather than exact fixed amounts. Values shift with the coin size and the number of lines in play.

The wild is the Cats logo. It substitutes for every symbol except the scatter and, crucially, it can appear as a split symbol too, so a single wild position can act as two wilds inside a winning line. The scatter is the paw print, and it also participates in the Split Symbols mechanic, meaning one paw print can be counted as two toward the free spins trigger.

Bonus Symbol Cross-Check

Because Cats is a single title, there is no divergence in bonus symbols across versions. The land-based cabinet and the online release both use the identical pair: the paw print as the scatter that launches free spins, and the Cats logo as the wild. There is no alternate bonus symbol, no secondary scatter and no version that swaps in a different trigger icon. Every form of Cats you can play, on a casino floor or in a regulated online lobby, uses the same paw-print scatter and the same logo wild.

How to Trigger the Bonus

The free spins round is triggered by the paw-print scatters. You need to land five or more paw prints, and in the base game these appear on the center reels, reels 2, 3 and 4. Landing five paw prints awards 5 free spins, while landing six or more awards 10 free spins. Because paw prints can arrive as split symbols, a single reel can contribute two toward the count, which makes the trigger easier to reach than a flat five-scatter requirement on a standard game. The scatters do not need to fall on an active payline to count.

How the Bonus Works

Once the free spins begin, the round plays out on the same 5-reel, 30-line grid with the bet and line count locked to the values from the triggering spin. The defining twist is that every win landed during the free spins is automatically doubled. Combined with the Split Symbols mechanic, that doubling is where Cats produces its largest results: a line of split cats that already stacks toward 10 matching symbols is then multiplied by two, which is how the game reaches its reported top payout of 10,000 times the stake. The wild logo still substitutes and still splits during the feature, and the split scatters continue to appear. The round does not retrigger, so the 5 or 10 spins you earn are what you play, but the doubled wins make even a short feature meaningful. There is only one bonus mode in Cats; there is no wheel, no pick round and no ladder, and the free spins play the same way in every version of the game.

Version by Version

Cats (Land-Based Cabinet)

Cats began life as a physical slot machine on casino floors, part of IGT’s long-running library of wildlife and safari cabinets. The exact floor debut year is not published by IGT, so it is listed as not published here rather than guessed. On the cabinet, the game ran the same 5-reel, 3-row layout with 30 paylines and the same Split Symbols mechanic that defines the online port. Return to player on physical machines is set by the individual casino within a range approved by the operator’s regulator, so the land-based RTP varies from property to property rather than sitting at a single fixed figure. Volatility remained medium, and the free spins round worked the same way, doubling wins across 5 or 10 spins earned from five or six paw-print scatters.

The land-based version is the origin of everything the online game inherited, and it is still found on floors that carry legacy IGT product. In this review it is treated as a distinct form only because its RTP is operator-set rather than fixed, and because its floor release predates the online adaptation. Mechanically it is the same game: the same big cats, the same logo wild, the same paw-print scatter and the same split behavior that lets a single symbol count double.

Cats (Online)

The online release is the version regulated US players actually spin today, and it is dated to 2015 by independent slot databases, arriving after the cabinet had already established the title. It is a faithful port: 5 reels, 3 rows, 30 adjustable paylines, medium volatility and a published return to player of 94.93 percent. That figure is below the modern online average of about 96 percent, which is a fair reflection of the game’s land-based heritage, and some operators may configure it slightly differently, so the effective RTP can vary. The online build keeps the Split Symbols system intact, keeps the doubled free spins and keeps the reported 10,000x stake ceiling.

What the online version adds is convenience and reach. It runs in a browser and on mobile, it supports autoplay, and it is available for free-play demo as well as real-money wagering inside licensed lobbies. This is the form of Cats that appears at BetMGM, Caesars Palace, FanDuel and Borgata in the states where those brands hold licenses. Because the specs match the cabinet, there is no separate spec table needed for the online release; the quick-view table above already reflects the online configuration players will encounter.

Strategy and Betting Notes

Cats has no skill element, because the reels are governed by a random number generator that decides every outcome independently, a system explained in the guide to how slot RNGs work. No betting pattern, stop-button timing or line configuration can change the long-run return. What players can control is bankroll management and stake sizing. Playing all 30 lines is standard because it keeps every winning pattern active and because the Split Symbols payouts depend on full-grid combinations. Trimming lines lowers the cost per spin but also removes potential winning positions, so most players leave all 30 on and adjust the per-line coin value instead.

Given the medium volatility and the below-average return, Cats suits players who want longer sessions with frequent small wins rather than those chasing a fast, high-risk jackpot. A practical approach is to set the line stake so that the top of your intended bankroll survives a cold streak long enough to reach the free spins, since the doubled-win round is where the game’s real value concentrates. For help matching a game’s risk profile to your own goals, the guide on how to choose a slot is a useful reference. As always, decide your budget before you spin and treat the free-play demo as a way to learn the Split Symbols rhythm before committing real money.

Mobile Play

Cats runs cleanly on phones and tablets through the browser and through the dedicated casino apps at the operators that carry it. The 5-reel grid scales down without losing legibility, the big-cat symbols stay easy to read on a small screen, and the spin and autoplay controls sit within thumb reach in portrait mode. The Split Symbols animation and the doubled free spins behave exactly as they do on desktop. For a wider look at handset play and which apps handle IGT games best, see the guide to mobile slots.

Where to Play

Cats is available inside licensed, real-money online casinos in the states where operators such as BetMGM, Caesars, FanDuel and Borgata hold gaming licenses, which currently includes New Jersey, Pennsylvania, Michigan and, for some brands, West Virginia. Playing inside a regulated lobby means the RTP is audited, payouts are enforced and your funds are protected.
