How to play Who Wants To Be A Millionaire Mystery Box mobile slot

The famous TV show is back, with the Who Wants To Be A Millionaire Mystery Box mobile slot bringing you big multipliers and one big question: should you gamble?

This is a mouthful of a name: having to read Who Wants To Be A Millionaire Mystery Box slot game over and over again will get as annoying as us having to write it – so you might forgive us if we use the shorter WWTBAM to describe it.

To be absolutely honest, other than the well-known logo, you may not know this has anything to do with the famous game show. You have a vague empty studio setting in the background, and then the gamble game has that famous diamond shape from the quiz questions.

Other than that, this is actually a fairly standard 5 reel and 3 rows 243 ways to win video slot, with high paying gems and then low paying Ace to 9 completing the paytable.

The free spins make this BTG slot shine

Big Time Gaming slots have big hits. Unfortunately, the big wins are almost always found in the bonus game.

Which makes the base game a little boring. Yes you go have wild symbols with a 2x multiplier, helping make the paytable wins a little more impressive.

And yes you get mystery symbols on 3 out of 5 reels, but they rarely do anything more impressive than give you a twinkle of animations on the reels.

The real wins in this Who Wants To Be A Millionaire Mystery Box slot is when you catch at least 3 scatters. Because then you start bonus games that are really surprising, thanks to increasing multipliers that increase the paytable value by up to 50 times.

The Millionaire Mystery Box slot is all about those multipliers

Every scatter you catch on this WWTBAM Mystery Box online slot gives you an additional free spin, but it also increases the multiplier.

You start with a 2x multiplier. No more than what you can get with the wild. But with every scatter things get more and more interesting, as the multiplier also increases. And who doesn’t love slots with multipliers?

Some rungs on this ladder actually give you +3 free spins, meaning that even if you only trigger 7 free spins, you can get to play at least 10 spins, if not more.

The problem is that it can take a while for those spins to hit. Thank-fully this has a generously low minimum bet of 0.10 a spin meaning you can bet low and increase as you get bigger wins.

Who Wants To Be A Millionaire Mystery Box Review Conclusion
