Cats is a medium-volatility slot. The RTP most commonly cited is 94.93%, though some operator configurations report figures as low as 93.04%, meaning the value depends on which build a casino runs rather than on anything a player does. The top theoretical payout sits at 10,000x stake, and hit frequency lands around 30%.
- RTP varies by operator configuration, not by how you play or bet.
- Medium volatility means frequent smaller wins with occasional larger split-symbol hits.
- The 10,000x max win is tied to the wild symbol landing the best possible line combination.
How the Split Symbols Shape the Numbers
Cats runs on a conventional 5x3 grid with 30 paylines, but its Split Symbols mechanic changes how those lines actually pay. Any cat icon, and the paw-print scatter, can land as a single animal or as a doubled pair occupying the same reel position. A payline win is counted by tallying cats along the line rather than by counting physical positions, so five reel positions can yield anywhere from three to ten matching symbols once doubles are added in. This is the main reason the game's payout distribution feels wider than a typical medium-volatility title with a plain 5x3 layout.
That mechanic also explains why the reported RTP sits in a band rather than a single fixed number. Sources consistently point to 94.93% as the figure used in most deployments, while at least one operator lists a lower configuration of 93.04%. Both numbers describe legitimate builds of the same math model; neither is wrong, and neither can be changed by adjusting bet size or line count on a given machine.
Hit frequency figures cited around 30% line up with what the split mechanic would produce: a fair number of small line hits from royals and mid-tier cats, punctuated by less frequent but noticeably larger wins when doubles stack up on an active line. The variance rating of medium reflects this balance — the split symbols push the ceiling higher without making the game swing as hard as a high-volatility cluster-pay title.
Free spins, triggered by five or more paw-print scatters landing on reels two through four, carry the split mechanic into the bonus round as well. Because scatters can also appear as doubles, the trigger itself can arrive faster than the raw reel count might suggest, and the feature retains the same underlying payline structure and RTP configuration as the base game rather than switching to a separate math model.
There's no bonus buy option and no cascading or tumble mechanic layered on top, so the split symbols remain the single defining variance driver in Cats. Everything else — line structure, wild substitution, scatter trigger — follows the standard video-slot template IGT used across its early-2010s catalogue.

Cats vs Other IGT Feline Titles
| Cats Diamond Spins | A later variant built around a different bonus structure; often confused with the original due to shared branding and theme. |
|---|---|
| Fort Knox Cats | Combines the feline theme with IGT's Fort Knox jackpot framework, shifting the payout structure toward progressive jackpots rather than split symbols. |
| MegaJackpots Cats | Adds a MegaJackpots progressive on top of a similar base game, changing the long-term RTP profile compared to the standalone Cats. |
| Cats Split 'n' Win | A newer title that keeps the split-symbol idea but restructures the paytable and features around it. |
Cats Through the Years

Questions About Cats' Math
Why do some casinos list Cats' RTP as 93.04% instead of 94.93%?
IGT ships the game with more than one RTP configuration, and operators choose which one to deploy. 93.04% and 94.93% are both documented values; the difference comes from the build a casino runs, not from anything a player controls.
Does the split-symbol mechanic affect the volatility rating?
Yes. Because a single reel position can double as two matching cats, payline wins can jump from a small three-symbol hit to a much larger seven- or eight-symbol combination, which is part of why the game carries a medium rather than low volatility rating.
How does a hit frequency near 30% translate into actual session play?
Roughly three in ten spins return some win, mostly smaller line hits. Longer gaps between wins are still possible, since the frequency figure is an average across all outcomes, not a guarantee of even spacing.
Can adjusting the number of active paylines change the RTP?
No. Line count affects how much of the 30-line structure is in play and therefore bet size and coverage, but it does not alter the underlying RTP configuration set by the operator.
Why does the max win figure sit at 10,000x rather than a fixed jackpot?
Cats is not a jackpot title; 10,000x stake is the top payout available through the standard wild symbol landing the best line combination, not a separate progressive prize.
Is the medium volatility rating consistent across all Cats configurations?
Sources describe the game as medium volatility overall, though the exact RTP figure used at a given casino may shift the balance of frequency versus payout size slightly within that range.
Does the paw-print scatter behave differently from a standard scatter due to the split mechanic?
Yes. Because paw prints can also appear as split doubles, the five-or-more trigger for free spins can be reached with fewer physical symbol landings than a standard single-icon scatter would require.
