There are an impressive selection of bet sizes on offer for players of Millionaire Mystery Box and BTG have set a minimum stake of €0.20, a decent spread of stake sizes then ensues before reaching the maximum bet of €100 a spin.
MILLIONAIRE MYSTERY BOX GAMBLE FEATURE
Big Time Gaming have decided to offer players of Millionaire Mystery Box the chance to gamble any wins that they achieve, and this opportunity is presented in the form of the gamble ladder. Players may be aware of this particular style of gamble feature from Novomatic slots such as Reel King, or Captain Venture.
You will be invited to try your luck to see if you can reach the top of the ladder to hit the set amount, if at anytime you wish to collect then you can do so, but players should be aware this as an all or nothing gamble, and an unsuccessful attempt will result in you walking away with nothing.
Big Time Gaming's mystery symbol on Millionaire Mystery Box can appear on reels 2, 3, and 4 only, and if any of these do land during your play they can reveal any symbol from the payable, including the x2 wild and the bonus scatter symbol. This can be a great way to help you trigger the free spin feature, or to hit some impressive wins if you can reveal 3 of the x2 multipliers.
MILLIONAIRE MYSTERY BOX WILD MULTIPLIERS
The x2 wild multiplier symbol on Millionaire Mystery Box appears on reels 2, 3, and 4. This symbol will substitute for all game symbols except the bonus scatter symbol. This multiplier symbol can potentially offer some big returns, as all wins are doubled for every wild present in that win.
MILLIONAIRE MYSTERY BOX FREE SPINS FEATURE
To trigger the free spins feature on Millionaire Mystery Box you will need to land 3 or more of the millionaire scatter symbols anywhere in view. The following amount of scatter symbols will award you with the corresponding amount of free spins.
3 Scatter Symbols - 7 Free Spins
4 Scatter Symbols - 12 Free Spins
5 Scatter Symbols - 20 Free Spins
As the feature begins on Millionaire Mystery Box you will notice a multiplier ladder situated to the left hand side of the reels. Your starting position on this ladder will be at the bottom where you are awarded a x2 win multiplier, to climb further up the ladder you will need to land the millionaire scatter symbols anywhere in view, each of these symbols that lands will move you one position further up the ladder, and offer you additional feature enhancements that are as follows.
1 Scatter Symbol will give you - x3 Multiplier & 1 Extra Spin
2 Scatter Symbols will give you - x4 Multiplier & 1 Extra Spin
3 Scatter Symbols will give you - x5 Multiplier & 3 Extra Spins
4 Scatter Symbols will give you - x6 Multiplier & 1 Extra Spin
5 Scatter Symbols will give you - x7 Multiplier & 1 Extra Spin
6 Scatter Symbols will give you - x8 Multiplier & 1 Extra Spin
7 Scatter Symbols will give you - x10 Multiplier & 3 Extra Spins
8 Scatter Symbols will give you - x12 Multiplier & 1 Extra Spin
9 Scatter Symbols will give you - x15 Multiplier & 1 Extra Spin
10 Scatter Symbols will give you - x30 Multiplier & 1 Extra Spin
11 Scatter Symbols will give you - x50 Multiplier & 3 Extra Spins
Players should note that if your reach the top rung of the ladder each additional scatter symbol that lands will award you with 1 extra spin.
The mystery symbol does like to drop in a lot during the bonus round, and this can reveal both scatter symbols and the wild multipliers, which can lead to some great wins.
MILLIONAIRE MYSTERY BOX SLOT REVIEW FINAL THOUGHTS
Big Time Gaming's second outing of the Who Wants to be a Millionaire Franchise has seen them move away from the Megaways™ engine, and try a more traditional 243 payline approach. There are a good blend of popular mechanics at work in Millionaire Mystery Box, and player favourites like the mystery symbol and progressing multiplier in the free spin bonus will offer solid entertainment.
There is undoubtably some big win potential on this slot, and with a 50x multiplier up for grabs during the bonus that could in theory combine with the 2x multipliers on the reels, the possibilities are endless when it comes to the multiple of your stake that could be returned.
