Who Wants to Be a Millionaire is a Megaways video slot based on the popular TV show that began airing in 1998.
Big Time Gaming were a fan, as they adapted it into a game, complete with cascading reels, extra reels, free spins, and win multipliers.
The hot seat bonus especially evokes the show, as it incorporates answering questions and using lifelines into the special feature.
You play this title on a 6×7 playing field, except you do not always have seven icons on a single reel. Instead, players get between two and seven symbols per reel. This means the theoretical 117,649 ways to win are incredibly rare, and usually, you get a lot less.

All the symbols on the playing field are rather generic.
Gamblers will see cascading reels, called reactions by the developers. Every time a winning combination is formed, the symbols disappear, making the existing icons fall, and new ones appear. With lots of luck, you can chain several wins this way when you play Who Wants To Be a Millionaire Megaways slot.
There are also several extra rows beneath reels two, three, four, and five in the Who Wants To Be a Millionaire Megaways slot. These act as separate reels, and new icons and symbols come from the side instead of up above. Feel free to treat them as extensions of the above reels.
Playing card royals like 9, 10, J, Q, K, and A are lower-paying icons. Higher-paying symbols are a green, blue, and red gemstone and a purple diamond. The said diamond is the highest-paying icon in the game.
Special symbols in the Who Wants To Be a Millionaire slot include a spinning, rainbow-coloured wheel as the Wild symbol and the TV show logo as the Scatter icon. The Scatter activates free spins.
There are 10 regular symbols, and here are their payout values per matching symbol:
You can familiarise yourself with these symbols in our Who Wants To Be a Millionaire slot demo.

Players must collect three Scatter symbols on the playing field, which will reward eight free spins and begin the Hot Seat Free Spins Gamble. If you activate the extra turns with four or five Scatters, you start with a stronger position in the Hot Seat.
For the duration of free spins, an unlimited win multiplier is active. Every time a win happens, the multiplier increases by one and keeps growing so long as players keep chaining wins together using the cascading reels. Finally, gamblers can win additional free spins by collecting three or four Scatters in the extra reel beneath the playing field.
The Hot Seat gamble takes you to a separate screen, where you select between four different answers to increase the number of free spins you get. Every time a correct answer is selected, you advance to the next rung.
There are twelve rungs, and players can start in three different positions. The rung you start on is determined by the number of Scatters that have triggered the bonus.
Three, four, or five Scatters start on the first, second, or third rung, respectively. Levels two and seven are safety nets, guaranteeing ten or twenty free spins once gamblers reach them. A maximum of fifty free spins can be won this way.
Finally, there are lifelines in case you get stuck with the answers. You get 50:50, used to remove two incorrect answers, Phone a Friend, which reveals the most likely answer, and Ask the Audience displays a percentage for each answer to determine how likely it is.

It doesn’t help if you read every single book in existence for this Who Wants To Be a Millionaire Megaways slot game, as knowledge won’t help you to win, as would be the case in the real TV show. Instead, it is all about luck!
The lifelines can give you some clues on which option to choose when you enter the hot seat, but this is a gamble in the end, as those guidelines are sometimes wrong.
What we suggest is that you decide your budget beforehand and then stick to it. You can also choose a win limit and leave the game if you reach it.
