How to play Millionaire Mystery Box slot
It's easy to get the reels spinning here. Set your stake using the left and right arrow buttons, with your chosen wager displayed on-screen. It may also be possible to utilise the game's
auto play function, allowing you to play multiple spins with a single click.
There are six low-value symbols on the reels, with playing card values from nine to Ace in-play. There are also red, green, blue and purple gems. The x2 multi-coloured symbol is the game's wild, which can substitute for any other symbol except the branded Who Wants to Be a Millionaire scatter.
During any base game spin, the Mystery Box Reveal feature can activate, turning any symbol on reels two, three or four into a wild or scatter to help form or improve pay-line combos.
Land between three and five scatters anywhere on the reels to bag between seven and 20 free spins. Land five scatters to start on the third rung of the 12-step multiplier ladder. With each scatter you land during your free spins, you'll move up the multiplier ladder, up to a maximum of 50x. Once you reach the top rung of the multiplier ladder, every scatter you land awards one extra spin of the reels.
Millionaire Mystery Box Maximum Win
The maximum pay-out available in Millionaire Mystery Box is set at 25x among the base game symbols and 50x in the Free Spins feature.
