Verdict

This is a beautifully designed slot with the potential of huge winnings in the Free Spin Feature

We think this is a much better version than the first Who Wants to Be a Millionaire from BTG in 2018, not that the first slot was any bad at all. But the overview of the new Millionaire Mystery Box just feels so much better and they removed the gambling feature in the free spin mode and replaced it with a ladder system you climb with each scatter you get during the free spins which we think was a good thing.

So what we really enjoy about this type of slot is the potential of the free spin feature, with the chance of reaching a multiplier on 50x with the possibility to get free spins added on top of that each turn. This is surely an amazing free spin feature that can pay big compared to other slots.

If you like playing slots that got a free spin feature with great potential we really recommend you to check out Who Wants to Be a Millionaire Mystery Box from Big Time Gaming.
