How to Play Big Box Bonus Online Slots
Before you can get started on Big Box Bonus online slots, you’ll need to set your total bet, which you can do by tapping the ‘Bet’ menu, found in the bottom left corner of your screen. Your total bet is calculated by multiplying your chosen bet-per-line by the number of win lines in play – in this slots show they’re locked to 20.
Using the ‘+’ and ‘-’ buttons in the ‘Bet’ menu, you can adjust your bet-per-line amount. The minimum you can bet over each line is 1p and the maximum is £5. For example, if you were to bet 10p per line, your total bet would be calculated as follows: 0.10 x 20 = £2.00.
On this online casino gameshow, any wins that you spin in are a multiplier of your bet-per-line. The amount you win will depend on which symbols have aligned and how many there are, and on these reels you’ll need at least three of the same symbol to line up.
To find out the all-important information about each and every symbol that you can spin in, you can visit the paytable which is located in the top-left corner of your screen. Once there, simply scroll through the paytable, or click the menu button once more to see each specific symbol section.
Don’t worry about missing a win as mFortune casino always puts a spotlight on any winning lines and will automatically add multiplier prizes to your in-game credit. Win lines pay from left to right on your reels and you can only win once on each individual line. Wins across several lines will be boxed up together to form a total big bonus prize!
You might want to hold the phone if you see your Wild symbol spin in on your reels, as this clever piece of tech has the ability to take the place of almost every other symbol on you reels, apart from Free Spins, to try and call you in a win.
When spun in, Wild symbols could turn a losing spin into a winning one, or land you with an even bigger multiplier prize. For example, if you found yourself with 3 ‘Q’ symbols on a win line, then you would already be on to a winner. However, if there’s a Wild symbol next to them on the win line, then your multiplier prize will increase to that of 4 ‘Q’ symbols!
In this online slots gameshow Wilds can also help you open up a big Box Bonus, by aligning with a number of corresponding coloured boxes. The multiplier amount the Wild symbol will pay, depends on the colour of the winning Box symbols. You can find the exact multiplier prizes in the ‘Wilds’ section of the paytable.
Although the Wild symbol is pretty show-stopping, you can’t call upon it to help you win the progressive Mega Jackpot. To walk away with that golden prize, you’ll need to spin in all 5 Jackpot symbols on a win line.
Bonus Boxes Feature
This online slots gameshow wouldn’t be complete without some big Bonus Boxes! If you spin in 3 or more matching coloured Box symbols on a win line, you could soon be unboxing a mega multiplier prize. It’s important to remember that all wins pay from left to right on a win line and not anywhere on screen.
During the main slots show, you have the chance to spin in Blue and Red Box symbols, with each box paying up to x100 and x250 respectively – the more boxes on the win line the higher the potential prize could be. The Gold Box symbols only appear during the Free Spins feature and each box could open to reveal an up to x500 multiplier prize!
As you’re spinning through the reels of Big Box Bonus, make sure to look out for the show’s host as they’re acting as your Free Spins symbol. Landing 3, 4 or 5 Free Spins symbols anywhere on your reels will unlock 5, 7 or 9 free spins respectively.
These spins are locked to the value of your last paid for spin, but don’t worry, you won’t be charged from your in-game credit- they’re a gift for being a contestant on mFortune’s Big Box Bonus online slots show!
Not only will you receive a number of free spins, but you’ll have also unlocked the opportunity to spin in the Golden Box symbol. Aligning 3 or more of these golden symbols on a win line could leave you with a star-studded multiplier prize.
Once you’ve taken all your free spins, you’ll return to the main stage to continue on your gameshow experience; with any winnings having already been added to your on-screen credit.
Progressive Mega Jackpot
The occurrence of “JACKPOT” symbols filling 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.
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.
The Mega Jackpot guaranteed starting value is £400,000, 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.
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.
