Stacking Bison: RTP and Volatility

The Stacking Bison slot has high volatility and an RTP of 94%. The RTP of Stacking Bison falls slightly below the average, which is one of the game’s main downsides. Most video slots nowadays offer an RTP of at least 96%, whereas Stacking Bison sits at 94%.

However, the game compensates with its high volatility. This means that although the risk is higher, and landing winning combinations may prove more challenging, you’ll be rewarded with significantly larger prizes compared to games with lower volatility levels.


Stacking Bison offers enticing bonus features that add to the excitement of the game. Let’s explore these features:

Bison Respin Feature

The Stacking Bison slot introduces a unique Bison Collection Meter. Each time one or more Bison symbols land on the reels, the meter increases by 1. Once the meter has reached 36 symbols, the respin feature will then be activated. During this feature, any reel can be replaced randomly with high-value symbols, increasing your chances of getting better payouts.

Free Spins

To trigger the Free Spins feature, you need to land a specific number of Scatters. The number of Scatters collected determines the number of free spins awarded. Three Scatters activate the round, granting 5 spins, while four Scatters offer 8 spins, and five Scatters award 15 free spins. Throughout the free spins, only high-value symbols appear on the reels, and each spin randomly replaces one or more reels with high-value symbols from the entire reel set.
