Who Wants to be a Millionaire: Mystery Box™
Millionaire Mystery Box Slot Review (Big Time Gaming)
Big Time Gaming’s Millionaire slot “sequel” is out now and it’s called Mystery Box™.
That Mystery Box is a mystery symbol feature, which BTG has introduced (in this format) for the first time. Who Wants to be a Millionaire: Mystery Box has also opened the door for Gamble mode enthusiasts to double or nothing on each win. The highlight of the game is of course a Free Spins bonus with win multipliers of up to 50x, which you’ll need to squeeze out every bit of the 22,000x maximum win potential. And it ain’t goin’ to be easy!
The Millionaire Mystery Box is available now exclusively at Rizk Casino until 20 November 2019, when it becomes available at other slot sites as well.

Base Game Features
Unlike the first game, Who Wants to be a Millionaire: Mystery Box is a non-MegaWays slot with 243 ways to win (like Book of Gods).
It’s one of the more simple Big Time Gaming slots with a 3×5 reel, featuring 6 low-paying card symbols and 4 Diamonds of which one (Purple Diamond) pays up to 25x per line. All symbols are non-stacked, which is one of the reasons base game wins tend to be depressingly small. Except in very rare cases when you get those Purple Diamonds lined up with x2 Wilds (see the screenshot below). Speaking of wilds, let’s move onto the more exciting features.
The x2 Wild appears on reels 2, 3, 4 only, and it doubles all wins. They also multiply each other (so three of these will give you x8), similar to the x3 Wilds in Opal Fruits. The 243 Ways really helps here and makes it easy to follow possible wins.
Mystery Box™ Feature
Mystery Box symbols also appear exclusively on reels 2, 3 and 4, and they reveal a random symbol (same one for all boxes), including the bonus symbol.
I don’t recall any other BTG slot having a mystery symbol throughout the game, but there’s no shortage of it in Blueprint MegaWays slots like Wish Upon a Leprechaun MegaWays! This helps to make the game less predictable and add a pinch of suspense, which starts to shine in the Free Spins.
For the first time, Big Time Gaming has also added a Gamble feature, which is available on every win (after the bonus too).
You can double or nothing up to 5x, similar to the ladder gamble on Merkur or Gamomat slots. It’s a small but very welcomed feature in an otherwise medium-volatility slot experience. All these features are also active in the bonus…
Free Spins Bonus
If you want to have any success in this game you need the Free Spins bonus.
Get 3, 4 or 5 Millionaire Scatters to win 7, 12 or 20 Free Spins. Also, the more Scatters you get, the better the starting multiplier. Unlike the MegaWays version of Who Wants to be a Millionaire, the game (for the first time again) features a Multiplier Ladder with 12 rungs:
- Multiplier x2 (default)
- Free Spins +1, Multiplier x3
- Free Spins +1, Multiplier x4
- Free Spins +3, Multiplier x5
- Free Spins +1, Multiplier x6
- Free Spins +1, Multiplier x7
- Free Spins +1, Multiplier x8
- Free Spins +3, Multiplier x10
- Free Spins +1, Multiplier x12
- Free Spins +1, Multiplier x15
- Free Spins +1, Multiplier x30
- Free Spins +3, Multiplier x50.
If you reach rung 12, each Scatter that you get will guarantee +1 Free Spin (no limits).
Watch out for the Millionaire (Bonus) symbols, because each one will level you up. As you can see, from level 10 it starts to get really interesting, however, Free Spin wins tend to be very volatile, so most of the time the game almost leaves no chance but to use the Gamble feature afterward. Avoid overusing it though, because after all WWTBAM Mystery Box has a fair RTP 96.36% without it.
The best I did in Free Spins after 10+ tries was around 140x.
Here’s the takeaway.
Win Up to 22,000x Bet
Who Wants to be a Millionaire Mystery Box is a nice addition to the first release that players from the UK and Germany especially would enjoy more thanks to the Gamble mode and a more classic feel.
From another standpoint, the base game is on the boring side and seemingly with not much win potential. Players who don’t care about the gamble feature may have trouble sitting through hundreds of spins that are usually needed to trigger the Free Spins (which don’t guarantee you’ll do any better). Hence, if you’re looking for more bang for the buck then be sure to check a highly-recommended non-MegaWays music slot of theirs: The Final Countdown.
