The Story behind the Who Wants to Be a Millionaire Slot

Who Wants to Be a Millionaire Slot by BTG

Most people associate the Who wants to be a Millionaire TV programme with dulcet tones of Chris Tarrant or, more recently, the love him or loathe him figure of Jeremy Clarkson.

Lovers of the show will be pleased to learn that the software developer of the slot, Big Time Gaming, has managed to capture the feel of the quiz show concept perfectly and as such, the Who wants to be a Millionaire slot is not only fun to play, but if you close your eyes, you could be forgiven for thinking Mr Clarkson was sitting next to you, asking if you would like to phone a friend or ask the audience!

Just What Makes the Who Wants to Be a Millionaire Slot Machine So Exciting?

The answer to that question would have to be the bonus round but before we get on to that, let’s look at the layout of the game and the different symbols which you should look out for. The symbols consist of the usual playing card symbols of Nine, Ten, Jack, Queen, King and Ace along with different coloured gemstones, with Purple being the most valuable. We have then got a question mark symbol which represents the Wild and the Who wants to be a Millionaire slot logo which represents the scatter symbol and is the key for triggering the bonus.

As the game is built on the Megaways platform, there are up to 117649 paylines; the exact number changes with every spin, so if you have never played a Megaways slot before, you are in for quite a treat. The way these types of games work is that when you get a winning payline or paylines, the winning symbols disappear, with new symbols dropping down to replace them.

The same process keeps on repeating until there are no new winning paylines.

Let’s Talk about the Who Wants to Be a Millionaire Slot Bonus

Millionaire Slot Machine Bonus - BTG

This is where it gets interesting. The main bonus is based on the opportunity to win up to fifty free spins, and in order to trigger the bonus, you need to get three of the scatter symbols (Millionaire logo) to appear anywhere across the paylines. You are then taken to a separate display where you are awarded an initial bonus of eight free spins but are given the opportunity to choose a final answer or walk away.

The “Walk away” option basically means that you accept the free spins which are awarded, but if you choose the final answer, you will be gambling the spins you have to try and get more. Every time you choose the final answer, the options to ask the audience, phone a friend or choose the 50/50 option will be given to you. Just like the TV show, if you keep choosing the final answer and get it correct, you will be a step closer to winning the main prize, unfortunately not a million pounds but instead, fifty free spins.

Don’t forget you can choose to walk away at any time and use the spins you have been awarded.

So, How Do You Play the Who Wants to Be a Millionaire Slot Game?

Don’t worry, setting the Who wants to be a Millionaire slot machine up to play couldn’t be easier because all that you really need to do is decide on the level of stake that you would like to use. The maximum bet size can depend on the casino where you are playing the game, but as we have already spoken about Betfair Casino in this Who wants to be a Millionaire slot review, we will use their stake sizes as an example.

If you look to the right of the reels in the game, you will see a ‘Stake’ option with two horizontal arrows, which you can click on to either decrease or increase the stake size and with Betfair Casino, the minimum is 20p and it goes up to a maximum of £6. Once your stake size has been set, simply click on the white arrow, which can be found below the ‘stake’ option and away you go, you are now playing the Who wants to be a Millionaire slot machine.

The RTP (return to player) figure for the Who wants to be a Millionaire slot is 96.27% which is not too bad, but it does mean that this is a slot with medium volatility. This basically means that you will encounter periods of gameplay without getting any winning paylines, so bear that in mind if you are thinking of jumping straight in with larger stakes.

What about the Animation and Soundtrack?

Big Time Gaming are renowned for producing online casino games with superb animations and soundtracks, and they have certainly excelled themselves with the Who wants to be a Millionaire slot game.

Let’s begin with the background setting to the reels, which looks just like it has been lifted from the TV programme. The symbols are crisp and clear, and even though the overall animations aren’t over the top in terms of flashing lights etc., they suit the game perfectly. An often-underestimated aspect of an online casino game is the backing soundtrack because one that is unsuitable can quite literally ruin the game.

No worries on that score with the Who wants to be a Millionaire slot soundtrack because it is the same as the TV show, and it really does add to the atmosphere of the game.
