Bonus Features and Free Spins
333 Boom Banks is loaded with cracking bonus bits. Mystery Symbols that reveal matches, Free Spins to keep the fun spinning, Multipliers to juice your wins, and Jackpots ready to pay out big. They all trigger on certain combos, opening more doors to proper payouts.
Free Spins
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 stack up to 40 Free Spins in 333 Boom Banks, giving you a proper long run and fatter wins.

Collect Free Spins Tokens — one of them might randomly launch the bonus round. When the round’s done, the counter drops back to 10 before you’re back in the base game.
Multiplier Bonus Feature
In the base game you’re nabbing Multiplier Tokens and popping ’em in the Multiplier Pot. Each one bumps your Free Spins multiplier by half an x, right up to a tasty 10x max. Those tokens can spark Free Spins out of nowhere.

If a token kicks it off, you get 7 Free Spins straight away. Round finishes, multiplier resets to 2x and you’re back to the main game.
Jackpot Bonus Feature
In the main game you’re scooping Jackpot Tokens that pump up the Mini, Minor, Maxi or Major pots. They can also spark Free Spins out the blue, unlocking those juicy jackpots for a proper shot at ’em.

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, may result in higher payouts.
