Rizk Casino has recently added the Who Wants to Be a Millionaire – Mystery Box Slot from Big Time Gaming to their casino, given the unusually long title for a slot we are going to call it the Mystery Box slot from now on!
With this release, Big Time Gaming has taken a step away from their incredibly popular Megaways slots and produced a slightly more regular 5×3 reel pay any way slot.
In true Big Time Gaming fashion though they haven’t just settled for a regular slot, this particular release has multiplying wilds that when several lands will combine together for even bigger multipliers, along with this feature you can also reach the dizzy heights of a 50x multiplier in the free spins round, this is before you even consider the multiplier wilds on the reels!
The Mystery box feature is a special symbol present on the reels, that reveal literally a mystery symbol each time, it could be a regular symbol or even a scatter, in our playtests we did have some unexpected bonus triggers thanks to this feature!
Whilst the base game does have the multiplying wilds and mystery box features the biggest excitement is definitely to be found in the free spins, where every scatter landing on the reels permanently raises the level of the multiplier along with granting extra free spins, all nicely tracked thanks to a progress meter to the side of the slot.
Various checkpoints along the way award 3 extra free spins rather than the usual one, reaching the top of this meter awards a 50x multiplier to any wins, factoring in the multiplier wilds also on the reels should give you a good idea of how crazy the wins could get with 5 of a kind wins and multiple wilds on the reels!
