333 Boom Banks 2 Power Combo Slot Bonuses and Features
Wild Symbols. Wilds substitute for all regular symbols except the Mystery Symbol. They also pay out their own combinations and help complete winning lines.
Mystery Symbols. Mystery Symbols appear stacked and transform into the same randomly chosen symbol before wins are calculated. If Mystery Symbols land with tokens attached, these are collected and used to trigger wheel features, jackpots, or bonus modifiers.
Wheel Token & Wheel Features. Landing a Wheel Token may trigger the Base Game Wheel (20 slices with cash prizes, jackpots, and Power Combo upgrades). Upgrade a cash prize or Power Combo slice on the wheel and trigger the Bonus Spins Wheel during bonus rounds. Cash prizes can reach up to 40x your bet, and respins may be awarded when certain slices are hit. The Bonus Spins Wheel outcome is shaped by how many Power Combo components are collected.
Bonus Spins. Bonus Spins tokens collected in the base game can store up to 40 spins. At any point, the feature may randomly activate, launching a round of free spins with multipliers, jackpot overlays, or both, depending on your Power Combo progress.
Multiplier Bonus Spins Feature. Collecting multiplier tokens increases the meter by +0.5x, up to 10x. During Bonus Spins, this multiplier applies to all line wins.
Jackpot Bonus Spins Feature. Jackpot tokens collected in the base game increase the values of the Mini, Minor, Maxi, and Major jackpots. During this feature, jackpot symbols overlay on reels. Collect them to fill a corresponding meter and win that jackpot. Grand and Mega jackpots are only available via specific feature combinations or wheel outcomes.
Power Combo Feature. This system allows multiple bonus features, Bonus Spins, Multiplier Bonus Spins, and Jackpot Bonus Spins, to be triggered simultaneously. The more features stacked, the more powerful the spin sequence becomes. Each bonus feature in the combo contributes its own set of spins (up to 7 per type).
Win Booster. When activated, the Win Booster doubles your stake but increases the chance of triggering Power Combo features.
