SlotRanker Score: 42 — Bison Bonus by Genii
https://slotranker.com/genii/bison-bonus#scoreSlot Summary
How It Plays
The base game uses 30 paylines across a 5x3 layout, with matching symbols paying along active lines from the left side.
A random Bison Stampede can place additional Wild Symbols on the grid, creating a sudden change without requiring the Free Spins trigger first.
Theme & Atmosphere
Animals and Wildlife dominate the American wilderness setting, with the bison supported by other creatures associated with open plains and mountain country.
The Cartoon treatment softens the Nature subject, presenting the herd's movement as a readable feature cue instead of a realistic wildlife scene.
Features & Win Potential
Random Wilds can appear through the Bison Stampede, adding substitution symbols to a base spin before ordinary payline results are settled.
Spreading Wilds or Wild Rush behavior changes during the bonus, where the Wilds roam between positions rather than remaining fixed throughout the round.
Bonus & Free Spins
Three or more Scatter Symbols trigger Free Spins, preceded by a selection that determines the number of spins and any accompanying modifiers.
During Free Spins, roaming Wilds move across the grid between rounds, and Additional Free Spins can lengthen the feature when its conditions are met.
