This cascading reel system allows the reels to cascade in both directions and is the perfect marriage to the Megaways™ functionality, propelling this game into an entirely new genre that engages players like never before! Dual Reactions adds a symbol to the reel it is below for reels 2, 3, 4 and 5 for a game fit to make millionaires!

Right before the Free Spins, the player gets a taste of what it's like to sit in the Hot Seat of Who Wants to be a Millionaire? game show. They get the possibility to climb the 12 rungs of the prize ladder, which contains 8-50 free spins! The more Millionaire Scatters land on the reels during the main game, the higher the rung the player starts in this mini game. While climbing the rungs, the player is offered three possible lifelines on each question: - 50:50 which removes two of the four possible answers - Phone a friend, which marks the most likely correct answer - Ask the audience, which reveals the chances of each of the four answers being the correct one. The player can then mark an answer—either A, B, C, or D—and click Final Answer to gamble for more Free Spins or Walk Away with the Free Spins they already have in store. Rung 2 and 7 do not offer a Walk Away option, as the rungs before them are safety nets, therefore these are risk-free rounds.

During the Free Spins round, each reaction increases the win multiplier by one. Three and four Millionaire Scatters appearing on the extra, horizontal reel will grant the player four and eight additional Free Spins, respectively! The original stake upon triggering the Free Spins will be used as a default wager during this Bonus Round.

Bustling players who cannot wait for the Millionaire Scatters to launch the Free Spins round can use the Bonus Buy feature. They will be granted 10 free spins at 75x of their original wager or 20 free spins at 150x of the original stake — starting on either rung 2 or rung 7 in the Hot Seat Free Spins Gamble!
