Description of the Slot 

The highly popular international TV show Who Wants to be a Millionaire? has become nothing short of a sensation. It’s an original British game show consisting of multiple-choice questions where the right answer takes you up the cash prize ladder. To carry forward the TV show’s craze, the innovative game provider Big Time Gaming released a slot of the same name in 2018. 

The Who Wants to be a Millionaire slot unfolds on 6 vertical reels and a horizontal one at the bottom. Each vertical reel can fit 2 to 7 symbols, thanks to BTG’s proprietary Megaways mechanic. Although the paylines keep shifting with a new spin, the maximum number ticks up to 117,649 ways to win. With features like Reactions, Free Spins, and the elaborate Gamble round, the gameplay immediately reminds you of the TV show. So, let’s proceed to the Hot Seat to find out what it has in store for us. 

Design and Audio

There is nothing much to discuss about the aesthetics of Who Wants to be a Millionaire since it’s a replica of the popular game show. As contestants sit at the centre of the studio, the grid is also placed in the middle of the screen. The reels are transparent, giving us a clear view of the studio behind the grid. An extra reel at the bottom gives you additional symbols for reels 2, 3, 4, and 5. 

The show’s famous music score is also audible here, especially after you tap the spin button. Overall, BTG has done an excellent job by keeping the online slot faithful to the TV game show. 


Although the slot has standard features, the Free Spins Gamble is created as a perfect rendition of the TV game. 


When you hit a win, winning symbols are removed from the grid and replaced by new symbols. If new symbols lead to another win formation, the reaction feature continues. Note that the reactions feature also applies to the extra reel

Free Spins 

Hitting 3 scatter symbols during the base game triggers the free spins feature. Initially, 8 free spins are awarded, but you can also opt for Heat Seat Gamble to increase the number of free spins. 

An unlimited win multiplier becomes active during free spins. Multiplier values begin at x1 and increase progressively with each reaction. Getting 3 or 4 free spins scatter symbols provides 4 or 8 additional free spins, respectively. Scatter symbols appear only on the extra reel. 

Hot Seat Free Spins Gamble 

If you opt to play the gamble round, you can win up to 50 free spins. To gamble, you must choose an answer from A, B, C, and D and tap the Final Answer button. If your guess is correct, you move up a rung in the free spins gamble ladder. Similarly, a wrong answer takes you down the prize ladder, or you might lose all your free spins. Rung 2 and 7 are safety nets, and reaching there guarantees 10 and 20 free spins, respectively. 

Players are given three lifelines during the gamble feature. They are as follows: 

  • 50:50 – two wrong answers are removed 
  • Phone a Friend – the most likely answer gets highlighted 
  • Ask the Audience – Odds for all the answers are revealed

Press the Walk Away button if you do not want to play the Free Spins gamble.  


The Millionaire slot features royal suits and gems in its paytable. Low-paying A to 9 card royals offer 0.8 to 1.75x the stake for landing six identical ones. Premium symbols are composed of four gems paying between 2x to 50x the total bet for lining up six matching symbols in a spin. The slot also features a wild symbol that substitutes for all symbols except scatters. However, wilds do not offer any payout. 

Who Wants to be a Millionaire is all about winning the maximum cap prize. As it turns out, the maximum win potential of the Millionaire slot is capped at a massive 72,310x the stake


The evident inspiration behind this BTG slot is one of the most popular TV shows on the planet, Who Wants to be a Millionaire? The slot meticulously includes several familiar elements from the TV show to give its fan a complete thematic experience. 


The Millionaire slot is not easy to crack, especially when the prize money is so high. To put it simply, Who Wants to be a Millionaire is a highly volatile slot with big risks and rewards going hand to hand in the game. 

About the Game Provider 

Big Time Gaming graced the igaming industry in 2011. In just a decade-long run, the company has garnered recognition from players and clients alike. While BTG has released excellent slots over the years, it is most famous for creating the popular Megaways game mechanics. Not only that, the game provider keeps experimenting with new engines, two of which include Megaclusters and Megapays system. 

With an ever-expanding gaming library, BTG slots are hitting the charts in online casinos, including several crypto-gambling platforms. 

Final Considerations 

Who Wants to be a Millionaire is a highly thematized slot with little room for innovation. The slot is made exclusively for fans of the show or those curious to play with this MCQ format in online casinos. But on paper, the game is equally solid with numbers. Whether you take the max win prize, volatility levels, or the above-average Return to Player of 96.27%, the slot arguably has one of the best math models.

Since the betting range is also within a feasible limit, even low rollers can jump into the Hot Seat to rake in large wins.
