Largely due to the success of its Megaways slot based on the popular TV quiz show, Big Time Gaming introduces a sequel for gamers looking for more and those not too fond of the Megaways mechanic. Who Wants to be a Millionaire Mystery Box slot is played on 5 reels and 3 rows with 243 Paylines.
A single spin on the reels could see a player cart away 12,000x the stake, all thanks to its numerous multipliers and freebies. Most of the bonuses offered by this slot can be triggered by landing the scatter symbol which is represented by the Millionaire logo.
Five scatters on the reels will get you up to 20 free spins with multipliers on your payout. As you play, you will climb higher in the multiplier ladder. At the top of the ladder is a 50x your stake multiplier. You can also trigger more free spins by landing extra scatters.
