I opened up a mystery box I found behind an old factory. It didn't have anything in, but was initially a mystery.
Millionaire Mystery Box is powered by Big Time Gaming and comes with 5 reels and 243 ways to win. Playable from just 20p a spin across desktop, mobile and tablet devices, it’s a slot based on Who Wants to be a Millionaire. It comes with a Mystery Box Reveal feature where you can get any symbol including the wild or scatter.
With slick graphics and animations, the soundtrack also portrays the show. With studio lights, symbols include A, K, Q, J, 10 and 9 royals – you’ll also see red, green, purple and blue gems.
The 2x Mystery Box is the wild symbol and replaces all symbols bar the scatter – it also doubles wins when part of a combination. If you get more than 1, the values are multiplied for huge wins.
Before we get to the exciting features, the ones with big multipliers, we will take a look at the wild symbol. This one has a 2x multiplier of its own, which it uses whenever it is part of a new winning combination, as a substitute. Should several wilds contribute to a win, they multiply those values, and you could end up with huge boosts to your wins.
Millionaire Mystery Box is a random bonus game, which will deliver random symbols, including scatters or wilds.
The most excitement appears to originate from the game’s free spins though. Triggering them via 3+ game logos, the slot’s scatters, you win 7 free spins initially. As you get scatter symbols in this mode, they are collected, and you get a higher multiplier. Each additional scatter also gives you 1 or 3 additional free spins, besides the boost to the multiplier. In total, if you get 11 scatter symbols, you receive an additional 17 free spins, for a maximum of 24 rounds, plus a multiplier of 50x is reached for the last few spins.
Millionaire Mystery Box, as the name suggests, comes with a Mystery Box Reveal feature – triggered at random, the Mystery Box symbol can reveal any symbol including the wild and the scatter. The wild will help form winning combinations and the scatter will help contribute to the following bonus feature.
Millionaire Mystery Box also comes with a Gamble feature – when you get a win, you have the option to double up. It’s a pretty standard feature but it ties in well with the theme and classic land-based feel. You can carry on doubling up until you reach the maximum payout/win.
This game is supplied by Big Time Gaming and is certified by the UK Gambling Commission as having been independently tested and up to the required standards for players in the UK.

Millionaire Mystery Box is all about the Free Spins feature - you will trigger the feature when you get 3 or more scatters (the Who Wants to be a Millionaire logo) – you will begin with 7 free spins.
You will notice there’s a free spin ladder system to the left of the reel set. Every scatter appearing during the free spin moves you up the multiplier ladder by 1 and gives you additional free spins:
This means you can collect 11 scatters during the feature to benefit from 17 extra free spins giving you a total of 24 free spins – the quicker you climb the ladder, the quicker you’ll play with a multiplier up to 50x.
A bet is placed only when it has been received by our server from your handset using our software. Once a bet has been placed it is final and binding and cannot be cancelled or changed. For the avoidance of doubt, a bet remains valid even if the result cannot for any reason be displayed back to your handset (due, for example, to a network failure, interruption of communication, or if you receive a phone call). In the event of a game termination, any relevant jackpot will be paid out on a random draw authorised by the regulator.
The theoretical average return to player (RTP) is up to 96.36%. This RTP represents the long-term expected payback of the game which has been calculated by an independent testing company and monitored monthly.
