There’s a brand new slot game available on Bonus Boss UK casino, introducing Mystery 7s online slots! This seven-ly slots game comes equipped with 9 locked win lines, Wild symbols, fun-filled Free Spins and there’s even a multi-coloured Mini-Game, 7th Heaven, where you could spin in some serious multiplier prizes!
As this is the current Game of the Month, when you take to these fun-filled reels for the very first time during the promotional period, you can get up to 35 Free Spins* to play with!
That’s not the only free bonus that you could pick up at Bonus Boss online casino, as after signing up and creating your very first account with us, you could get up to 100 Free Spins** to use on the reels of one of our most popular online slot games.
Take a spin in 7th Heaven!
This colourful mini-game could leave you spinning in winnings! Whilst you’re on the reels of Mystery 7s, make sure to look out for the Mini-Game symbols, as spinning in 2 or more of them on a win line will grant you entry into this feature.
Once inside, you’ll come face-to-face with a multi-coloured board filled with multiplier prizes, ‘Collect’ and ‘???’ tiles. To get the mini-game started you’ll spin the wheel and move the corresponding number of spaces along the board.
If you land on a multiplier prize tile, this will be added to your in-game credit and you’ll spin again. Coming to a stop on a ‘???’ segment will award you with a mystery multiplier prize up to x400!
You’ll continue to spin, collecting multipliers as you go, until you land on a ‘Collect’ tile. This will bring the 7th Heaven mini-game to an end and you’ll return to the main reels with any winnings having already been added to your on-screen credit.
Go Wild for this mysterious symbol
On the colourful reels of Mystery 7s online slots, you have the opportunity to spin in the infamous Wild symbol. If spun in, it has the ability to take the place of almost every other symbol on your reels and could turn a losing spin into a winning one, or even increase the value of a winning spin.
For example, if you were to align 3 Green Crown symbols on a win line, then this would already be a pretty regal win. If there’s a Wild symbol next to them on the win line, this will take the place of a 4th Green Crown symbol and grant you a x150 multiplier prize.
Despite being a seven-ly symbol there are a few powers the Wild cannot possess. The Wild symbol is unable to take the place of Free Spins or Mini-Game symbols, or award you the progressive Mega Jackpot. To take home the Jackpot crown, you’ll need to spin in all 5 Jackpot symbols on a win line. Don’t worry though, spinning in Wild and Jackpot symbols could still equate to a winning combination!
There’s seven-ly Free Spins waiting to be won!
Spinning in 3, 4 or 5 Free Spins symbols in any order on an active win line, on these colourful reels, will award you with 5, 7 or 9 free spins respectively.
These spins are locked to the value of your last paid for bet amount, but you won’t be charged for these spins – they’re a gift from the Bonus Boss!
After taking your free spins, you’ll return to the main reels with any winnings having already been added to your on-screen credit.
Don’t forget, that as Mystery 7s online slots is Bonus Boss’ current Game of the Month, you can get up to 35 Free Spins* the very first time you play, during the promotional period.
