Theme: TV Gameshow

High Value Symbol: Purple Gemstone

Compatibility: Mobile, Tablet, Desktop


The design in the Who Wants to be a Who Wants to be a Millionaire Megapays slot will be instantly recognizable if you’ve seen the Who Wants to be a Millionaire TV gameshow. The famous studio is the setting.

Following on from the original Who Wants to be a Millionaire Megaways game, there’s a glossy, high-spec feel to the visuals here. You’ll hear the famous Millionaire theme tune blasting away in the background while you spin. There’s no shortage of atmosphere here.

The reels are made up of lower value A to 9 symbols. Potentially more lucrative are the 4 jewel symbols. The best paying symbol is the purple gemstone which delivers an award of 50 x your total stake if you land of them in combination.

The golden ? is the wild symbol. This substitutes for all the standard symbols in a winning combination. The famous Millionaire logo is the scatter symbol. Landing 3 or more of these on the same spin triggers the Free Spins feature.

Who Wants to be a Millionaire Megapays Mobile


Big Time Gaming has created versions of Who Wants to be a Millionaire Megapays which has been fully optimised for desktop, tablet and mobile devices. The Megaways game engine means there are plenty of moving part but the slick visuals and animation are more than up to the job.

Who Wants to be a Millionaire Megapays Bonus features

Many of the features that have made the Millionaire slots so popular are present and correct in Who Wants to be a Millionaire Megapays. There’s one big difference though. The Megapays version adds a progressive jackpot element that can deliver some potentially enormous rewards. In total, there are 5 bonus features.

Reactions feature

After a winning combination is formed, the Reactions feature follows. The successful symbols are blasted off the reels and new ones drop down and replace them. A new payout consideration then follows. The reactions keep on coming as long as a new winner is formed. This can be found in most Megaways games and is also referred to as Cascading Wins or Tumbles.

Megapays feature


The Megapays feature is triggered by landing a colossal Megapays version of one of the A, K, Q, J, 10 or 9 symbols. A special spin then follows. If a Megapays symbol lands, it locks in place and a respin follows. Respins then keep on coming as long as a new Megapays symbol lands.

Landing 4 or more matching Megapays symbols delivers a progressive jackpot. Keep track of the number of Megapays symbols you’ve collected via the Megapays Ladder. The Mini, Midi, Major and Mega jackpots are seeded at £100, £1,500, £20,000 and £300,000 respectively but they can get much higher. In fact, there’s no cap on the prizes. Here’s what you need to do to win:

Number of Instances Jackpot Seed Amount
4-7 Mini £100
8-11 Midi £1,500
12-14 Major £20,000
15+ Mega £300,000

The current Mega Jackpot is £844,406.98.

Free Spins feature


Land 3 scatters on the same spin and you’ll trigger the Free Spins feature with 8 free spins. You can increase this haul courtesy of the Hot Seat Free Spins Gamble feature.

Just like in the TV show, you can use lifelines to work your way up the ladder and win more free spins. Choose one of the A, B, C or D answers. At each gamble, a lifeline is given. Here’s what you can use:

Ask The Audience answer odds are revealed
Phone a Friend the most likely answer is revealed
50/50 2 incorrect answers are removed

Don’t worry if you’re not a trivia king. They’re not quiz questions. Losing a gamble can result in a loss of free spins. There are safety nets along the way. Once you pass these milestones, you’re guaranteed to win a specified number of free spins. For example, once you reach level 2 on the ladder, you’ll play 10 free spins. Reach level 7 and you’re guaranteed to win 20 free spins. Reach the summit of the bonus ladder and you’ll play 50 free spins. You can Walk Away at any stage and claim your current number of free spins.

Once in, you’ll begin the feature with a 1x multiplier in play. The win multiplier increases by 1 each time you land a reaction win. This is known as the Unlimited Win Multiplier feature. Multipliers don’t reset following a winless free spin either, they continue to rise.

Finally, retriggers are possible here too. Landing 3 or 4 scatters during the bonus round will add another 4 or 8 free spins to your current total. You can benefit from unlimited extra free spins.

RTP (96.38%)

Max Win (72,310 x)


The Who Wants to be a Millionaire Megapays slot is very similar to the non-jackpot version. The obvious difference being the addition of the 4 progressive jackpots which can deliver some potentially massive prizes.

As with the original game, the design is very classy and there’s plenty going on courtesy of the Megaways reactions and free spins with increasing multiplier. The unlimited win multiplier is the key to winning the max 72,310 x stake wins per free spin.

If you’re a fan of the TV show or you’ve enjoyed the other slots in this series, Who Wants to be a Millionaire Megapays is well worth a look. However, the RTP for the actual game is much lower so the max payouts (jackpots excluded) will be much harder to achieve:

Megapays = 86.94% RTP (excluding 9.44% for jackpots) Megaways = 96.27%

Overall, it’s down to whether you like jackpot slots or not. The gameplay is identical with the bolt on of the 4 progressive jackpots. What you lose is 9.44% of the RTP.

You should try Bonanza Megapays which is the jackpot version of the popular Bonanza Megaways. Whilst it offers the same functionality and bonus features, the max win is the Megapays version is 17,926 x stake compared to 12,000 x stake in the original.

BTG also have a jackpot version of Star Clusters Megaclusters, named Star Clusters Megapays. With the 4 same progressive jackpots available in Who Wants to be a Millionaire Megapays, the max win is 27,050 x stake compared to 23,960 in the original.
