How Big Bass Boom Works

Base Game Mechanics

Big Bass Boom plays on a 5-reel, 3-row grid with 10 fixed paylines. All wins pay left to right starting from the leftmost reel. The game features 10 regular symbols plus special scatter and wild symbols that only appear during free spins.

In the base game, fish symbols display random money values ranging from 2x to 5000x your total bet. These values are visible but cannot be collected until you trigger the free spins feature with 3 or more scatter symbols.

Scatter Assist Features

When exactly 2 scatter symbols land without a third, Big Bass Boom can randomly trigger assist features:

  • Scatter Respin: Scatters move down one position and reels without scatters respin
  • Hook Pull: A hook pulls one reel up to potentially reveal another scatter symbol

Free Spins Feature

Land 3, 4, or 5 scatter symbols to trigger 10, 15, or 20 free spins respectively. Before the round begins, you'll randomly receive 0 to 5 pre-round modifiers that enhance your chances.

During free spins, wild fisherman symbols appear on all reels. Each wild collects every money fish value visible on the screen at that spin. The collected amounts are multiplied by your current level multiplier.

Wild Collection Progression

  • Level 1 (0-3 wilds collected): 1x multiplier
  • Level 2 (4th wild): 2x multiplier + 10 more spins
  • Level 3 (8th wild): 3x multiplier + 10 more spins
  • Level 4 (12th wild): 10x multiplier + 10 more spins

All wilds collected during the feature remain displayed until the round ends. After level 4, no further retriggers are possible, but you continue playing remaining spins with the 10x multiplier active.
