333 Boom Banks Power Combo Slot Review

As part of our expanded gaming coverage on Betfred Insights, we will be doing regular reviews of new and classic slot games that you can find on the Betfred Games section. 

Next up is a relatively new release from the people at Fortune Factory Studios that has quickly become a firm favourite in the iGaming community. Here is our 333 Boom Banks Power Combo Review...

This fun little slot from Fortune Factory is the follow up to the popular April 2024 release 333 Fat Frogs Power Combo and follows a very similar format to its predecessor, where you have a standard-looking 5x3 grid and 20 winlines. On virtually every spin in the base game you can land mystery symbols that can stack up to decent sized wins.

However, the real fun in this game comes from the three progressively growing vaults that expand every time you land a corresponding-coloured symbol and when the vault is 'full', it explodes to launch one of the three bonus games. Fill more than one vault at once and you can play simultaneous bonus rounds at the same time! Also, when you leave the slot and come back next time, the vaults will remember your position, so you don't need to start from scratch.

The three bonus rounds are Free Spins, Multiplier and Jackpot and when used on their own or especially in combination, can pay massive amounts, rising up to 12,000 times your initial stake.

So what are you waiting for? Get breaking into those vaults!
