How the Game Plays

Bison Boom by Northern Lights Gaming takes players to the sun-drenched plains of the American wilderness, featuring a standard 5x3 grid framed by rugged mountains. The base game is driven by a medium volatility math model, offering a balanced flow of wins across 20 fixed lines. While low-tier poker royals provide frequent small returns, the high-value animal symbols—including raccoons, eagles, wolves, and bears—offer payouts up to 8x the stake for five of a kind. The Bison itself acts as the wild, substituting for all regular symbols to complete winning lines.

Bison Wild Boom Explained

A standout feature in the base game is the Wild Boom mechanic. As you spin, mini dynamite tokens can appear on the reels and are collected into a wooden crate beside the grid. At any moment, this crate can randomly explode, triggering the Bison Wild Boom. This blast showers the reels with up to 15 wild symbols, often turning a losing spin into a significant multi-line win.

Bison Spins and Link&Win

Landing three scatters triggers the Bison Spins bonus, which utilizes a Link&Win respins mechanic. The round begins with three respins on a special grid where only cash-carrying Moon symbols and special modifiers can land. Landing any new symbol resets the respin counter to three. The feature is enhanced by the Feature Upgrade Meter, which tracks pairs of scatters landed during the base game to unlock up to four additional rows for the next bonus round. During the spins, players may encounter Adder symbols that increase all values on the board or Splitter symbols that double symbol positions. Filling the entire grid awards a fixed top prize of 2,000x the bet.
