Who Wants to Be a Millionaire Mystery Box Slot Review

• The millionaire slot machine in Las Vegas is always one of my favorites. There is something so wonderful about picking the answers and seeing what sort of bonus you can get. Of course, whether you get answers correct or not relies on random luck in the slots, rather than skill, but it's still great fun to play.
• Who Wants To Be A Millionaire Megaways is a slot machine by Big Time Gaming. According to the number of players searching for it, Who Wants To Be A Millionaire Megaways is not a very popular slot. Still, that doesn't necessarily mean that it's bad, so give it.

Bonus Features

The slot has a rainbow-coloured wild that can appear on reels 2, 3 and 4. This wild substitutes for all of the standard symbols and act as a bonus to help you form winning combinations. Whenever the wild helps you win, it doubles the value of your winnings. If you happen to form a winning combination with more than one wild, the multipliers are stacked together. If there are two wilds, your wins are multiplied by 4x, for example, and if there are three, your wins are multiplied by 8x.

One of the main features is Mystery Box. On any random spin, Mystery Boxes can land on reels 2, 3 and 4. These boxes open to reveal the same matching symbol – it can be any of the slot's standard symbols, or it can even be the wild or the scatter.

Speaking of the scatter, it's linked with the free spins round. It appears as the Who Wants to Be a Millionaire Mystery Box free slot machine logo and rewards both payouts and free spins.

• Two Scatters: 2x payout
• Three Scatters: 5x payout and seven free spins
• Four Scatters: 20x payout and 12 free spins
• Five Scatters: 200x payout and 20 free spins

When you trigger the free spins round, a ladder with 12 rungs on it appears to the left of the reels. You start off at the bottom rung, which gives you a 2x multiplier. While free spins are in play, ever scatter that appears on the reels moves you up one rung. Each rung after the first gives you a number of extra free spins and increases the value of the multiplier, as seen below:

• First Rung: 2x multiplier
• Second Rung: 3x multiplier and one free spin
• Third Rung: 4x multiplier and one free spin
• Fourth Rung: 5x multiplier and three free spins
• Fifth Rung: 6x multiplier and one free spin
• Sixth Rung: 7x multiplier and one free spin
• Seventh Rung: 8x multiplier and one free spin
• Eighth Rung: 10x multiplier and three free spins
• Ninth Rung: 12x multiplier and one free spin
• Tenth Rung: 15x multiplier and one free spin
• Eleventh Rung: 30x multiplier and one free spin
• Twelfth Rung: 50x multiplier and three free spins

Once you've hit the twelfth rung, whenever you land any additional scatters you'll get one extra free spin per scatter.

How to Win the Game

The Who Wants to Be a Millionaire Mystery Box slot doesn't have set paylines that you need to form winning combinations on to receive payouts. Instead, the slot uses the all-ways-win system. This does away with paylines and lets you win if you land three or more matching symbols on consecutive reels starting with the leftmost one. It doesn't matter what positions the symbols are in, so long as there is one on the first three reels.

There are 10 standard symbols that you can win with when playing the Who Wants to Be a Millionaire Mystery Box slot game.

• Low-paying symbols – The six low-paying symbols are card ranks, each one of which is a different colour. The least valuable are the turquoise 9 and the yellow 10; the green J and blue Q both offer the same higher payouts, while the red K and purple A both offer even higher payouts.
• High-paying symbols – As for the high-paying symbols, these are four gemstones. There's a green pentagon, a blue hexagon, a red octagon and a purple one in the shape of a circle. The most valuable standard symbol is the purple gemstone. Should you land one of these on each of the five reels, you'll be paid a sum equivalent to 25x your bet. This symbol is the only one to offer payouts for two on consecutive reels (all of the other symbols payout for three or more only). Land one purple gemstone on the leftmost reel and another on the reel next to it for a payout equal to your current bet.

Whenever you win, you'll have the chance to gamble your winnings. A 'GAMBLE' will appear following every win. Give this a click, and you'll get to gamble up to five times. Each time you gamble, there's a 50% chance you'll double your winnings, and a 50% chance you'll lose them all. If you double your winnings, you can gamble them again up to a maximum of five times. If you're lucky enough to gamble five times, your winnings will have been multiplied by 32x!

📌 What happens if you form a winning combination with more than one winning symbol on a reel?

Let's say you form a winning combination with three A symbols. There are no other A symbols on the reels. You're paid accordingly. If you land several A symbols on each of the first three reels, you've technically formed more than one winning combination, so your payout will be bigger.
