Special Features

Our slot includes multiple bonus mechanics. Features like Mystery Symbols, Free Spins, Multipliers, and Jackpots increase winning potential. Each feature activates under specific conditions, providing additional ways to land payouts.

Mystery Symbols

Mystery Symbols land on the reels and transform into a random symbol before payouts are calculated. They can reveal any symbol except another Mystery Symbol, ensuring variety in every spin. All Mystery Symbols on the reels display the same symbol per round, increasing the chance of forming winning combinations.

Mystery Symbol Feature in 333 Boom Banks

Some revealed symbols may include tokens, which are automatically collected. When Mystery Symbols stack and cover all reel positions, they trigger a blackout, awarding payouts across all paylines at the current bet.

Free Spins Bonus Feature

Free Spins Tokens appear in the base game and are collected in the Free Spins Pot. Each collected token has a chance to randomly trigger a Free Spins round. You can accumulate up to 40 Free Spins, increasing their chances of extended gameplay and bigger payouts.

When a Free Spins Token is added to the pot, the feature may activate at random. Once the round ends, the Free Spins counter resets to 10 before returning to the base game.

Multiplier Bonus Feature

Multiplier Tokens are collected in the base game and stored in the Multiplier Pot. Each token increases the Free Spins Multiplier by 0.5x, with a maximum multiplier of 10x. These tokens can randomly trigger Free Spins, applying the accumulated multiplier to any winnings during the bonus round.

Jackpot Bonus Feature

Jackpot Tokens are collected during the base game and can increase the values of the Mini, Minor, Maxi, or Major Jackpots. These tokens may also randomly trigger Free Spins, where jackpots become available.

Jackpots can only be won if Free Spins are triggered by a Jackpot Token. If activated this way, 7 Free Spins are awarded. Jackpot values scale based on the bet size, giving bigger rewards for higher stakes.

Power Combo™ Free Spins

The Power Combo™ Free Spins feature activates when any combination of Free Spins, Multiplier, or Jackpot Tokens is collected. This allows multiple bonus features to trigger simultaneously, increasing payout potential.
