Big Bass Halloween by Pragmatic Play: headline RTP 96.06%, Medium volatility, max win x2 100.
An RTP of 96.06% means a house edge of 3.94% — the expected cost is 3.94 units per 100 staked over the long run, whatever a single session does.
Big Bass Halloween sits at medium volatility — a middle profile where wins are neither rare nor frequent enough to dominate a session.
The advertised ceiling is x2 100. Max win figures describe the tail of the distribution, not a realistic target: on most games with a ceiling this high the probability per spin is below one in a million.
We measured 5 different RTP builds of this game across casinos: 96.04% at the best and 96.04% at the worst, a 0.00pp spread. That is the same game costing meaningfully more to play at one operator than another, and it is the reason we track builds at all.
Against our catalogue the number is below the median of 96.13%, higher than 40% of the games whose RTP we verified. That comparison matters more than the raw figure, because "96%" only sounds generous next to nothing.
Hit ratio is 14.3%, meaning roughly 14 spins in 100 return something — most of them less than the stake. A hit is not a win.
Features: Bonus Buy, Bonus Game, In-game Freespins. Note that studios frequently ship the bonus-buy path at a different RTP than the base game, and the lobby rarely says which figure it is quoting.
Released 2023-10-23. Release date matters for RTP: newer titles are more likely to ship with several configurable builds, which is what lets two casinos price the same game differently.
Stakes run from 0.01 to 3.75 per spin on a 5-3 layout with fixed betways.

Yes. Big Bass Halloween has a free demo with the same mathematics as the real-money version — the only thing that changes is that the balance is not yours. A demo cannot tell you the RTP build a particular casino serves.
Big Bass Halloween is a Pragmatic Play game, so the outcome is produced by the studio's certified RNG rather than by the casino, and it is not provably fair in the cryptographic sense — you cannot recompute a spin from a seed. What the casino does control is which RTP build it serves, and on this title we measured a 0.00pp spread between operators. That is the real variable, and it is measurable.
Of the operators we measured, Stake serves the highest build at 96.04%. The full per-casino table is on this page, and our RTP builds report explains how the measurement works.
