Millionaire Mystery Box Free Demo Play

Big Time Gaming was the first game studio to bring the popular TV show Who Wants To Be a Millionaire to the reels. Similar to the TV equivalent, the casino players who made it to the top of the ladder can be counted on the fingers of one hand. Nevertheless, the slot became a huge hit and even received a Megaways treatment.

Now, BTG is readying a variation of Who Wants To Be a Millionaire. The Millionaire Mystery Box is a 5-reel, 243 ways to win slot. What makes it different from the original is the presence of a Mystery Box feature that reveals random symbols, including premium ones.

Millionaire Mystery Box - Slot Review

Design-wise, the Millionaire Mystery Box is not a big departure from the original. The symbols you will land include A to 9 royals, as well as better paying gems in different colours. The multicoloured symbol is the wild that appears on the middle reel only.

Mystery Box Feature

When a Mystery Box symbol appears on the reels, all instances of it transform into a random symbol

Gamble Feature

Whenever you land a win, you can either keep what you won or try to double the amount. The Gamble feature gives you the chance to make it gamble your way up to the top, but do not underestimate game’s volatility. One wrong move and you lose all your winnings.

Free Spins

Land 3 scatters and get 7 free spins to start with. On the left of the reel set, you will see a ladder with multipliers and free spins. The multiplier and free spins you get are determined by the number of scatters you land during the free spins round.

*The Millionaire Mystery Box is still in the works. We will update this review once it goes live.
