About Big Bass Halloween
Just when we thought it was impossible for Pragmatic Play‘s partner studio Reel Kingdom to milk to “Big Bass” franchise even further, they go out and release Big Bass Halloween, a reskin of Big Bass Bonanza.
So Big Bass Halloween is not really a new game, just a spookier version of the slot that started the whole fishing slot craze. Although technically, that isn’t really true as the original mother of all fishing slots is, of course, Reel Time Gaming’s Fishin’ Frenzy.
Both the fish and the fisherman have been given a scarier look, with the fish showing sharp, bloodied teeth and the fisherman sporting a hook that is big enough to land a Killer White shark.
Big Bass Halloween RTP
Big Bass Halloween has been released in three payout configurations, swimming in at 94.09%, 95.09%, and 96.06%. Make sure to only play this slot in the highest possible setting to avoid giving online casinos more margin than absolutely necessary.
Advantages of playing Big Bass Halloween with a high RTP
As we will show you, playing Big Bass Halloween on a lower payout version can significantly decrease your chances of winning as you get fewer spins and also give you less entertainment time on average by making a poor choice.
To illustrate the effect of a lower RTP, we have made some calculations. In the following table, we show how many spins you will theoretically get to play before your money runs out, based on a starting balance of €/£/$/100 and a stake of €/£/$/1 per spin.
RTP | Number of spins |
96.06% | 2,512 spins |
95.09% | 2,016 spins |
94.09% | 1,675 spins |
The different percentages may not look like a big deal, but you can see how your choice of RTP version can interfere with your chances of winning.
