How This Book of Cats Review Was Tested

Testing started with long sessions at low stakes to get a feel for how often the free spins round actually shows up, since a very high volatility rating on its own says nothing about pacing. Several thousand spins later, the pattern matched what third-party tracking sites report: long dry stretches punctuated by a single feature that reshapes the whole session.

The base game got separate attention. Line hits with the lower symbols were tracked to see whether they carry any of the session on their own, and they mostly don't — small wins keep the balance moving without doing much for it. The bulk of anything meaningful came from either a strong premium symbol hit or the bonus round itself.

Bet-size testing covered both the low end and higher stakes to see how the swings scale, since the game's payout ceiling is defined as a stake multiple rather than a flat figure. Moving up in stake didn't smooth anything out; it just made the same streaky pattern hit harder.

Mobile testing was done on a mid-range phone browser rather than a dedicated app, since the game runs through casino platforms rather than as a standalone download. Load times and symbol animation held up fine, with no functional gaps against the desktop version during testing.

What Testing Confirmed and What Remains Unverified

One point is worth stating plainly and only once: the RTP figure differs between sources. The studio's own game page lists 96.99%, while several independent slot databases cite 94% instead. Testing sessions here are not long enough to settle which figure applies to any specific casino build, so both are noted rather than picked as the 'real' one.

Everything else lined up cleanly with the official listing. The very high volatility label matched the observed swings, the free spins feature behaved as an expanding-symbol round rather than a flat multiplier bonus, and no bonus-buy option appeared anywhere in the tested lobbies.

The stated payout ceiling — a multiple of the stake, capped in euros — was not something reachable through manual testing, as is normal for a max win of that size. It's reported here as a documented figure rather than something personally verified through play.

Availability also has a caveat worth passing on: the studio itself notes the game runs on limited servers and recommends checking with individual operators before assuming it's listed. That matched testing experience, where the title showed up on some Canadian-facing platforms and not others.

For anyone comparing notes against similar titles, such as the Megaways version or other 'Book of' style Egyptian slots, the base structure here read as more classic and less feature-dense — a straightforward book slot rather than a mechanic-heavy modern release.
