How to Play Mystery Box Mobile Slots

  1. Set your total bet amount. Before you can star in the Mystery Box show, you will need to set your total bet. This is calculated by multiplying your bet-per-line by the number of active win lines in play, which on these golden reels are locked to 20. To adjust your bet-per-line, use the ‘+’ and ‘-’ buttons, found in the ‘Bet’ menu in the bottom-left of your screen, the minimum you can bet is 1p and the maximum is £10. If you were to bet 10p per line, your total bet would be £2 per spin.
  2. Check the paytable. As a contestant on Mystery Box, you might want to get familiar with the slots symbols and how you can spin in a win. Before going live, we suggest visiting the paytable, which is located in the Menu, at the top-left of your screen.
  3. Understand reel wins. Your reel wins pay from left to right across your 20 locked win lines and the value of a winning combination will depend on the type of symbol you’ve spun in and how many of them there are on the win line. For some symbols you’ll need 2, whilst for others you’ll need at least 3. To learn more about these showbiz slots, visit the paytable.
  4. Spin the reels! Once you’re ready for the episode to begin, press play, by tapping the ‘Spin’ button and watch your reels start to spin!

Wild Symbols

You could be going wild if you spot this contestant on your reels. Not only is she dealing with The Boss, but she’s also acting as your Wild symbol. The Wild is an A –Star standard symbol and has the ability to take the place of almost all other symbols to try and open up a win.

For example, if you were to spin 2 ‘Q’ symbols in on a win line, you’d have just lost out on a win. However, your luck could be about to change if there’s a Wild symbol, as it will take the place of a 3rd ‘Q’ symbol and award you with a multiplier prize!

This symbol is no phoney, but there are a few things she cannot do. The Wild is unable to take the place of Free Spins or Bonus symbols and can’t sweet-talk its way to the progressive Mega Jackpot. To walk away with the prize, you’ll need to spin in all 5 Jackpot symbols on a win line.

Mystery Box Mini-Game

Things are about to get pretty golden if you spin in 3 or more Gold Box symbols anywhere on your reels, as you’ll have just opened up the Mystery Box mini-game. The more symbols you enter with, the bigger the potential multiplier prizes.

Now is your turn to step into the spotlight. In front of you will be 18 golden boxes, each containing a mystery multiplier. Once you’ve chosen your box, you will select 3 additional boxes to be removed from play and their corresponding multipliers will disappear from your screen.

The Boss will then call you up to make you a multiplier offer. Accept and you’ll head back to your reels with that prize; decline and you’ll continue on 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.

Here you will be asked if you would like to 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 and you’ll head back to the main reels a Mystery Box master!

Free Spins

Whilst you’re spinning through the slots show, make sure to look out for the fabulous Free Spins symbol. 5, 7 or 9 free spins are awarded when you spin in 3, 4 or 5 Free Spins symbols anywhere in view on your reels.

These spins are locked to the value of your last paid for spin. You won’t be charged from your in-game credit though, as these spins are a gift from The Boss, to say thank you for playing.

Once you’ve used up all your free spins, you’ll head back to the main stage, where you’ll continue on the hunt for the Mystery Box multipliers. Any winnings from your free spins will have already been added to your on-screen credit.

Progressive Mega Jackpot

The occurrence of 5 (five) “JACKPOT” Jackpot symbols on an active win line awards the progressive Mega Jackpot. The progressive Mega Jackpot is available on any bet, with 0.025% of the bet being added to the progressive pots. Half of the value gets added to the current jackpot, and half to a reserve pot ready for the next winner. The Mega Jackpot starting value is £50,000, with even higher starting prizes possible with a built up reserve pot. The Mega Jackpot promotional pot system is available over any stake on any participating game plugged into the Mega Jackpot promotional pot. When the Jackpot is won, it is reset and begins to rise again. Simultaneous wins can occur. If a player wins the progressive Mega Jackpot then a notification would occur BEFORE any other player was awarded the Jackpot. Any players in a game that contributes to that same Mega Jackpot will receive the on-screen notification of a reset the next time they press the spin button if it is within 10 minutes of the jackpot being won. Players will not be charged for the spin generating this notification. In the event of a communication error after a progressive win result has been determined and before it has been displayed on screen, the win amount will automatically be transferred to the player’s account. While the game is live, the Jackpots cannot be terminated.
