Review for Millionaire Mystery Box

Millionaire Mystery Box is a new NYX slot game that’s about the Who Wants to Be a Millionaire TV game-show we all know and love. Weirdly enough, the symbols are the 9 to A playing card symbols and different coloured gems on a background of the show’s set.

We don’t really think the symbols work, but it’s ok because the game totally compensates with the bonus features. You can get multiplier wilds, mystery box, themed gamble feature and free spins with up to 50x multipliers. The fact that these features remind us of the show makes everything much better. 


  • Nice theme
  • Good RTP
  • Fun themed bonus features


  • Graphics could be better, symbols are out of place
