Who Wants to Be a Millionaire Slot Review
Who Wants to Be a Millionaire by Big Time Gaming is one of the most thrilling branded slots we’ve tested. Released in November 2018, this was BTG’s first venture into licensed game territory, and they made quite an entrance. The slot brilliantly captures the tension and decision-making drama of the iconic TV show, translating it into genuinely compelling bonus mechanics. With 117,649 ways to win and a maximum payout of 50,000x your stake, there’s serious potential here for the right player. We found this slot particularly exciting for high-volatility enthusiasts willing to chase the Hot Seat gamble feature for extended sessions.
Base Game & Features
The base game operates on a 6-reel grid with variable rows (2-7 per reel), giving you that ever-changing Megaways feel with 117,649 ways to win on each spin. This creates an exciting dynamic where no two spins feel identical. The cascading reels mechanic (called Avalanche in BTG terminology) is a standout feature—every win triggers a respin as symbols cascade down and new ones fill in from above. We found this mechanic creates a genuine rhythm to the game, keeping the base game engaging even during dry spells.
Big Time Gaming added a few unique touches to this branded release. There’s a sixth reel that slides in occasionally, packed with exclusive wild symbols that expand when they land. You’ll also encounter the Global Multiplier during the base game, which starts small but builds with each cascading win. These features give the base game more personality than your standard Megaways slot, though we’ll be honest—the focus here is definitely on triggering the bonus.
- Paylines: 117,649 ways to win (Megaways system)
- Grid Layout: 6 reels with variable 2-7 rows per reel
- Bet Range: 0.20 to 20 per spin
- RTP: 96.24% (main version)
- Volatility: High (extremely volatile during bonus rounds)
- Cascading Reels: Unlimited respins after every win
- Sliding Sixth Reel: Extra column with exclusive wild symbols
Bonus Features & Free Spins
The bonus round is where Who Wants to Be a Millionaire truly shines. Land three or more scatter symbols anywhere on the reels and you’ll trigger the free spins feature, starting with a minimum of 8 free spins. Here’s where it gets interesting: the Global Multiplier system kicks in during the bonus. Unlike traditional multipliers that reset after each spin, this one builds continuously during free spins, increasing by 1x for every winning combination. This unlimited multiplier potential is what creates the genuine big-win opportunities—we’re talking 50,000x your stake maximum.
But the real star is the Hot Seat feature. After your free spins end, you’re thrust into an interactive gamble screen directly inspired by the TV show. You make a critical decision: take what you’ve won, or gamble for more. If you gamble, you face high-stakes questions with lifelines at your disposal—50:50 (eliminating two wrong answers), Phone a Friend (indicating the likely answer), and Ask the Audience (showing probability). Get it right, and you can climb up to 50 total free spins. Get it wrong, and you lose the lot. It’s genuinely nerve-wracking, and that’s precisely the point. Our team found this mechanic creates tension that rivals the TV show itself.
What makes the Hot Seat particularly engaging is the genuine interactivity. You’re making real decisions that impact the outcome—it’s not just passive spinning. Combined with the unlimited retriggering of free spins and the escalating multiplier, you’ve got a feature that can deliver life-changing wins if fortune smiles on you. However, it’s also high-risk. Many players find themselves gambling spins they’ve accumulated and losing them all, which is why this slot commands such strong opinions from the community.
- Free Spins Trigger: 3 or more scatter symbols
- Initial Spins: Minimum of 8 free spins
- Unlimited Retriggers: Land scatters during bonus to extend
- Global Multiplier: Starts at 1x, increases by 1x for each win (unlimited potential)
- Hot Seat Gamble: Interactive feature with TV show lifelines
- Bonus Buy: Not available—must trigger organically through scatter symbols
Our Honest Verdict
Who Wants to Be a Millionaire is an exceptional slot for a specific type of player—the high-volatility enthusiast who craves interactive bonus features and genuine decision-making. The Hot Seat gamble mechanic successfully translates the TV show’s dramatic tension into engaging slot gameplay. It’s genuinely compelling, not just window dressing. Combined with the 117,649 Megaways system and the unlimited multiplier potential during free spins, the game creates legitimate opportunities for substantial wins.
That said, this isn’t a slot for everyone. The high volatility means you’ll face extended dry spells between bonus triggers. Base game wins are rare, and the focus is almost entirely on hitting and extending the free spins feature. Some players find the base game stretches feel static and unrewarding. The Hot Seat gamble also introduces genuine risk—you can lose everything you’ve accumulated if your luck turns. This is the type of feature that divides players sharply: some love the tension, others find it frustrating.
What impressed us most is how authentically Big Time Gaming captured the TV show’s essence. This was their first branded game, and they clearly invested effort into making it feel special. The lifelines system, the decision-making pressure, the visual theming—it all works cohesively. If you’re a fan of the show or you appreciate high-volatility slots where individual spins can produce life-altering payouts, Who Wants to Be a Millionaire deserves serious consideration.

- Best For: High-volatility enthusiasts, TV show fans, players seeking interactive bonus features
