Our rating:
  • Based on the incredibly popular game show of the same name
  • Gamble feature lets you gamble every win
  • Free spins can lead to impressive multipliers

Who Wants To Be A Millionaire Mystery Box slot from Big Time Gaming is based on the hit TV show now hosted by Jeremy Clarkson which can see players win up to £1million. You won’t be winning that much here, but with some good multipliers, payouts can be quite impressive.

Less impressive is the design of this slot. The graphics are quite poor and it’s not as exciting as a slot with this theme could be. You have 5 reels with 3 rows offering 243 ways to win. To get a win, you need to land base symbols from left to right which are as follows, ranked in ascending order based on their value:

  • 9 or 10 (lowest value)
  • Jack or Queen
  • King or Ace
  • Green Jewel
  • Blue Jewel
  • Red Jewel
  • Crystal (highest value)

Who Wants To Be A Millionaire Mystery Box Slot Bonuses and Features

Wild Symbols. As with most slots, wild symbols are available here, appearing on reels 2, 3 and 4. They substitute for all other symbols in a winning combination apart from the scatter symbol. Not only that, but every win that uses a wild symbol will be doubled for twice the rewards.

Mystery Box. Mystery boxes are available on reels 2, 3 and 4 as well. They work like any other mystery symbol, with all instances of them turning into a randomly chosen symbol.

Gamble Feature. A fairly common feature, this allows you to gamble every win for double or nothing. You can do this up to 5 times if you’re feeling brave.

Free Spins Bonus. To trigger this you need to land 3, 4 or 5 scatter symbols anywhere on the reels. This will award you with 7, 12 or 20 free spins. Once triggered, you’ll notice a multiplier ladder with 12 different sections. The multiplier shown will be applied to all wins. For every scatter symbol that appears, you’ll move one up the ladder. Each rung awards an additional number of free spins apart with sections 4, 8 and 12 giving you 3 free spins. If you make it to the top then every extra scatter gives you 1 more free spin.

Who Wants To Be A Millionaire Mystery Box slot from Big Time Gaming obviously has a very familiar theme and it’s not the first time we’ve seen a slot based on the popular TV show. This version from Big Time Gaming has a few features, most of which you’ll be familiar with. These include wild symbols, which also have multipliers on them, mystery symbols and a gamble feature. The free spins bonus is, as you’d expect, the exciting part where bigger wins are likely to be had. You can work your way up the ladder for big multipliers and more free spins which works pretty well, but I have to say the slot as a whole just isn’t as exciting as it could have been in my opinion. I think they could have done something with lifelines to make it more like the show, and the base game could have more going on too. Overall, it’s pretty decent with some nice wins to be had, but it’s not that exciting. You can see more of their other slots here.
