|Who Wants to Be a Millionaire – Mystery Box Slot – Technical Summary|
|Re-Trigger Bonus Round||Extra Spins|
|RTP (Return To Player)||96.64%|
The Mystery Box is a special symbol on the reels, when landing in view it will transform into any symbol, including the Scatters which trigger the bonus round
The Multipliers wilds are present on the middle three reels and will double any win (2x) if multiple wilds land in view they are multiplied together, so 3 wilds would apply an 8x multiplier to the wins.
The free spins bonus round is triggered by landing 3 or more scatter symbols on the reels, additional scatters award more free spins and will also start the climb up the multiplier ladder in the bonus round.
For example, a 4 scatter trigger will award 12 free spins and you start the bonus round at the 3x multiplier level.
Every time a scatter lands in view on the reels the multiplier level rises to the next level and you are awarded at least 1 extra spin, a few checkpoints will award 3 free spins instead.
If you manage to reach the 50x multiplier level then any additional scatters will simply add more spins.
The Mystery Box slot from Big Time Gaming will probably be popular with players but possibly the main reason being the “Potential” of this machine, there is no denying that 50x multipliers and multiplying wilds could create some staggering wins in relation to stake size.
In our playtests, we managed wins of well over 200x stake and managed to reach above the 10x multiplier level a few times, getting to the 50x multiplier is likely to be much less common as we expected, there is also a nice gamble feature available on all wins with 5 levels of gamble on offer which if you are lucky could transform a small win into something huge.
The biggest gripe we did have with this slot though was that it didn’t feel particularly fun to play, the potential on offer excited us to try and discover big wins, but the actual slot wasn’t great fun to play at the same time, more of a set it to autoplay and wait for a bonus trigger feeling.
Worth trying if the prospect of crazy multipliers appeals to you!
