What is Millionaire?

Millionaire is a 6x2-7 video slot from Big Time Gaming with a 96.27% RTP, medium-high volatility, and a top win of 70,000x your bet. Its Megaways engine delivers up to 117,649 ways to win on every spin.

The Reactions mechanic removes winning symbols and drops new ones into place, allowing chains of consecutive wins from a single spin. Combined with an escalating multiplier during free spins, that reaction loop is how the game reaches its upper payout ceiling. A rainbow-colored question mark Wild lands on the extra reel and substitutes for all paying symbols, extending winning combinations across the Megaways grid. Big Time Gaming built this around the Who Wants to Be a Millionaire television brand, pulling lifeline icons and the show's visual language directly into the reel set.

Millionaire Slot Theme & Graphics

The game replicates the set design of the original Who Wants to Be a Millionaire television show: a darkened studio, the contestant's hot seat at the center, and the concentric circles of studio lighting overhead. Symbols carry the show's iconography: the clock graphic, lifeline buttons, and diamond prize icons against a deep blue and gold color scheme.

Big Time Gaming kept the audio consistent with the show's tense orchestral stings. The reel animations are clean, with symbols growing slightly before a Reactions clear and the multiplier counter animating upward during a winning chain. The game scales to vertical mobile mode without losing the studio atmosphere, so the full visual experience carries across devices.

Millionaire Slot Symbols & Paytables

Understanding the symbols in Millionaire is straightforward: card royals fill the low end, show-branded premiums fill the top tier, and two special symbols drive the features. The slot machine symbols follow the usual Megaways distribution, appearing 2-7 per reel so their frequency shifts on every spin.

Low Value Symbols

The low-value symbols are the classic card royals: A, K, Q, J, and 10. These pay smaller but more frequent amounts across the 117,649 ways grid. Because Megaways collapses and expands every reel on each spin, card royals can appear anywhere from 2 to 7 times on a single reel, meaning even lower-tier wins can cover multiple lines simultaneously. Their payouts are modest by design: they keep the base game paying regularly without cannibalizing the premium symbol returns.

High Value Symbols

The premium symbols are drawn directly from the television show: a diamond icon, the audience applause meter, the phone-a-friend lifeline graphic, the 50:50 icon, and other show-branded images. The diamond is the highest payer, awarding 50x the stake for six across the reels. These symbols only appear occasionally given their higher pay rates, but when a Reactions chain clears a full set of low-value symbols they begin clustering together more often. The show-theme framing means each premium has an immediate visual identity that makes big wins easy to read on screen.

Special Symbols

The Wild is a rainbow-colored question mark that lands exclusively on the extra horizontal reel above the main grid. It substitutes for all regular paying symbols, extending any adjacent combination that would otherwise fall short. The Scatter is the legacy Who Wants to Be a Millionaire show logo: landing 3 or more anywhere on screen triggers 8 free spins with the escalating multiplier active from spin one.

Millionaire Bonus Feature & Special Features

Megaways

Big Time Gaming's Megaways engine assigns a random number of symbols to each of the 6 reels on every spin, between 2 and 7. The maximum configuration produces 117,649 ways to win. This means the grid is never static: a spin producing 7 symbols per reel covers vastly more winning combinations than one producing 2, and you cannot predict the payline count in advance. The practical effect is that wins feel different every spin, and a reel expansion toward the 7-symbol maximum meaningfully increases the chance of a longer Reactions chain.

Reactions

When a winning combination lands, every symbol in that win is removed from the grid and new ones cascade from above to fill the gaps. If the new arrangement creates another win, those symbols are removed and the process repeats. This can chain multiple wins from a single spin without any additional cost. In the base game, Reactions are the primary engine for building mid-size payouts; in free spins, each winning Reaction also increments the multiplier, making long chains exponentially more valuable.

Multiplier Free Spins

Landing 3 or more Scatter symbols triggers 8 free spins. A multiplier counter is active from the first spin and starts at 1x. Every winning Reaction during the bonus increases the multiplier by 1, and there is no ceiling: a spin that chains many consecutive reactions will apply a large multiplier to the final win in that chain. The Hot Seat Gamble feature runs alongside: players who answer questions correctly can push the free spins count up to 50, giving more opportunity for the multiplier to climb. This combination of reaction chains and an uncapped multiplier is where the 70,000x max win is achievable.
