How to Play Mystery Box Online Slots

Before peeking inside any boxes, you’ll need to set your total bet. This can be done in the ‘Bet’ menu in the bottom left of the screen. The minimum your bet-per-line can be is 1p and the maximum is £10.

Your total bet is calculated by multiplying the bet-per-line amount by the amount of win lines. On Mystery Box Slots, win lines are locked to 20. So, if you select a value of 10p for your bet-per-line amount, this will be multiplied by the 20 locked win lines to give you a total bet of £2.00 per spin.

Reel Wins

There’s no business like show business! On these glitzy reels, wins are a multiplier of your bet-per-line. They also depend on which symbols you have, and how many appear on a win line. To earn a win here, matching just 2 symbols on a win line could be enough.

To find out more about symbols and their values, head on over to the ‘Paytable’ in the top-left corner of your screen. Winning lines are instantly highlighted on the reels and added to your credit automatically.

Win lines pay from left to right, and you can only win once on each individual line. However, wins across several lines will be added together to form one flashy win!

Mystery Box Feature

There is nothing boxy about this feature! To enter this golden Mini-Game, you need to spin in 3 or more Gold Box symbols anywhere on the reels. The more symbols you enter with, the bigger the potential multiplier prizes.

You will then be faced with 18 golden boxes, with each one containing a mystery multiplier. You then choose 1 box. This is your box to keep hold of throughout the feature and the multiplier inside it stays hidden until the end of the Mini-Game. Next you choose 3 boxes to get rid of – their corresponding multipliers will disappear from your screen. Your original box stays unopened and will be opened at the end if you don’t swap it for another box.

You will then receive a phone call from The Boss who will make you an offer. Accept and you’ll head back to your reels with that prize; decline and you’ll keep going and remove a further 3 boxes. This will continue until you either accept an offer from The Boss OR you get down to the final 3 boxes.

You will then be given a choice. You can either stick with your original box or swap it for one of the remaining two still in play. Once your choice is made, your golden prize will be revealed! You will then head back to the main reels with your prize!

Free Spins

For an extra touch of show biz magic, you could earn some fantastic Free Spins. Spin in 3, 4 or 5 Free Spins symbols anywhere on the reels and you’ll be rewarded with 5, 7 or 9 Free Spins, respectively. Plus, all these spins are free! That’s not a boxy prize at all!

Free Spins are locked to the value of your last bet-per-line amount from your last paid-for spin.

Wild Symbols

TV shows are wild! And Mystery Box is no exception. This game is brimming with Wild symbols that can take the place of all other symbols – except the Bonus symbol and Free Spins symbols.

Although the Wild is certainly a helpful symbol, it cannot win you the Progressive Mega Jackpot. To steal this away from The Boss, you’ll need to spin in all five Jackpot symbols on a win line. A combination of Jackpot and Wild symbols could still win you a fancy prize, though.

Progressive Jackpot

The occurrence of 5 (five) “JACKPOT” Jackpot symbols on an active win line awards the Progressive Mega Jackpot which has a guaranteed starting value of £100,000. You can find out more on how the Progressive Mega Jackpot works by going to the Mega Jackpot info page.
