Who Wants to Be a Millionaire Mystery Box Review

Who Wants to Be a Millionaire Mystery Box slot review

Who Wants to Be a Millionaire Mystery Box Reviewed by Casinogamesonnet.com

Big Time Gaming has had some success with their first branded slot, Who Wants to Be a Millionaire. However, this game has taken some criticism over its lack of large payouts.

So, Big Time Gaming (BGT) has already come out with a sequel in Who Wants to Be a Millionaire Mystery Box. Like its predecessor, Millionaire Mystery Box revolves around the UK television hit Who Wants to Be a Millionaire. But it also includes differences that make it slightly more enjoyable than the first slot.

Gameplay and Atmosphere

Not much has changed with the atmosphere in Who Wants to Be a Millionaire Mystery Box. It brings back the same replica gameshow set as the first slot. You’ll see empty audience seats, neon lights, and the “Hot Seat” in the background.

One major change is the format of Millionaire Mystery Box. The original Who Wants to Be a Millionaire features BTG’s famed Megaways setup. The sequel, however, has five reels and a 243-ways format.

Megaways has become popular for offering countless ways to earn payouts. But it doesn’t really have much of an impact in Who Wants to Be a Millionaire, due to the lack of big prizes. The switch to 243 ways is a positive one in Mystery Box.

Betting options range from €0.20 to €100. The highest-possible win is worth 12,000x your stake (w/ multipliers included). Return to player (RTP) is a respectable 96.64%.

Symbols include a wild, game logo, Mystery Box, different-colored gems, A, K, Q, J, 10, and 9. The purple gem pays the most at 25x your stake. BGT isn’t exactly shaking up the industry with these symbols, but they did include a couple of icons based on the show.

Who Wants to Be a Millionaire Mystery Box Slot Special Features

Wild Symbol Multiplier – Appearing on reels, 2, 3, and 4, the wild symbol substitutes for everything except the scatter icon to form wins. It also multiplies all payouts that it helps form by 2x.

Mystery Box Feature – Landing on reels 2, 3, and 4, the Mystery Box icon can transform symbols into wild and scatter icons.

Mystery Box Free Spins – You trigger 7, 12, or 20 free spins by landing three, four, or five scatters anywhere on the reels. This bonus also includes a 12-step ladder that offers a multiplier and extra free spins. At the highest level, you’ll receive a 50x multiplier on all wins.

Gamble Option – You can attempt to double any payout up to a maximum of five times.

Final Thoughts on Who Wants to Be a Millionaire Mystery Box Slot

The initial Who Wants to Be a Millionaire is a quality game. Nevertheless, BGT went back to the drawing board after complaints over the limited big prizes. Who Wants to Be a Millionaire Mystery Box is the product of these efforts.

We can’t say that Millionaire Mystery Box is a dramatic improvement over its predecessor. But it certainly brings a fresh take to the series with its 243-ways format and Mystery Box bonuses. It also offers the same stage-based background.

Assuming you like the first slot and/or same-titled game show, then you should definitely appreciate Millionaire Mystery Box.

Release Date
