How the video slot works

Hybrids between traditional slots and arcade games tend to bring their own and sometimes unusual gameplay, but that’s not the case here, even though this one is armed with a rewarding Mystery Box feature.

So, what you get are 5 reels, 3 rows, and 243 ways to benefit from symbols of both lower and higher payout rating. Gems of different colors dominate over Royal Symbols, which aren’t that lucrative.

After each winning combination or when granted by the system itself, you can turn on the Gamble feature and double your winnings step by step until collecting the prize – or until the point you give a wrong answer. Let’s just hope it won’t ever happen.

The Millionaire Mystery Box Free Spins feature is the core of this game and starts when you get 3 or more Scatters. Initially, you’ll start off with 7 spins, but keep a close eye on a meter placed leftmost since every new Scatter moves up the ladder.

Basically, the first new Scatter increases the Multiplier to 3x adding +1 extra spins, the second rises the value to 4x and so on. Finally, if lucky enough to collect 11 Scatters in a row, you’ll receive a 50x Multiplier and +3 new spins.

This doesn’t mean you’ll run out of spins since this streak goes for as long as Scatters arrive and may lead to the Millionaire Mystery Box Big Win of 12000x your stake.

With the same set of rules, the Millionaire Mystery Box Free Play calculated all bets and prizes in demo credits. You can also activate the paytable for 3+ matchings and wager between 0.20 and 100 credits per round.
