Who Wants to Be a Millionaire Mystery Box Bonus Features

After playing the game for quite some time, I’ve only managed to find 3 bonus features, with the main highlight being on Mystery Box Reveal and Free Spins

Let’s have a closer look at how there features operate:

Mystery Box Reveal

As the name implies, Millionaire Mystery Box has a Mystery Box Reveal feature that can, at random, be triggered by the Mystery Box symbol and reveal any symbol, including the wild and scatter. The scatter and wild both contribute to the next bonus feature’s formation of winning combinations.

Free Spins

The Who Wants to be a Millionaire logo serves as the game’s scatter symbol. Three or more symbols will activate the feature, starting you off with seven free spins.

You’ll see a ladder-style system for free spins to the left of the reel set. Every scatters that appears during a free spin awards an additional spin and moves you up the multiplier ladder by one.

  • The first scatter gives you an additional spin and raises the multiplier to x3.
  • The second scatter triggers an x4 multiplier increase and one additional spin.
  • The third scatter triggers 3 additional spins and increases the multiplier to x5.
  • The fourth scatter raises the multiplier to x6 and awards you an additional spin.
  • The fifth scatter raises the multiplier to x7 and awards you an additional spin.
  • The sixth scatter gives you an additional spin and raises the multiplier to x8.
  • The seventh scatter increases the x9 multiplier and three additional spins.
  • The x12 multiplier and one additional spin increase with the eighth scatter.
  • The ninth scatter gives you an additional spin and raises the multiplier to x15.
  • The tenth scatters you an additional spin and increases the multiplier to x30.
  • The x50 multiplier and three additional spins are increased by the eleventh scatter.

As a result, during the bonus round, you can collect 11 scatters to earn an additional 17 free spins, for a total of 24 free spins. The faster you climb the ladder, the faster you’ll play with a multiplier up to 50x.

Gamble Feature

Additionally, Millionaire Mystery Box has a Gamble feature that allows you to double your winnings after a win. Although it is a fairly common feature, it fits in well with the theme and has a traditional land-based feel. You can keep doubling up until you win the most money possible.

Graphic, Theme and Soundtrack

When Who Wants to be a Millionaire by Big Time Gaming was released in 2018, it became an instant hit, and the company wanted to follow it up with another fantastic title. But it’s challenging to create an online slot that’s even more thrilling than a Megaways slot—or is it?

The new Millionaire Mystery Box provides players just as much excitement and fun as the first game. Given the crowded market for Megaways games, it may become more well-liked by players.

The game show backdrop and vibrant jewel-themed symbols are similar to those in Who Wants to be a Millionaire Megaways in terms of visual presentation. Overall, it’s a game that catches your attention and is eye-catching.

The purple gemstone is by far the highest value symbol in this game, and the symbols are accurate to the Who Wants To Be A Millionaire game show.

  • Purple gemstone: 25x the bet for 5 lines.

  • Blue gem: pays 2.5 times for 5 on a payline.
