How to Play Stack Spin Win Online Slots
- Set your total bet amount. Before you can start stacking up those wins you’ll need to set your total bet. Using the ‘+’ and ‘-’ buttons, found in the ‘Bet’ menu, you can adjust your bet-per-line amount. Your total bet is calculated by multiplying your bet-per-line by the number of active win lines, which in this game are locked at 20. You can bet between 1p and £10 per line, so setting a bet of 10p per line would make your total bet £2.00 per spin.
- Check the paytable. Before you get started on your neon adventure you might want to take a trip to the paytable, found in the menu at the top-left of your screen. Here you will find everything you need to know about these retro reels and the symbols they hold.
- Spin the reels! To start stacking, spinning and winning, all you need to do is tap the ‘Spin’ button.
Reel Wins
Any wins that you spin in will always be a multiplier of your bet-per-line. The value of your multiplier prize will depend on the type of symbol you spin in and how many of them there are. In this neon jungle you will need at least 3 matching symbols to stack up a win.
We’ve raised the Bar on these retro reels, as when it comes to the Bar symbols, you can spin in mixed wins. Any combination of mixed Bar symbols on a win line will leave you with a multiplier prize. To learn more about how to spin your way to a win, make sure to visit the paytable.
On this bright, bold slots game all wins pay from left to right on your reels. Any winning lines will be highlighted on screen and automatically added to your in-game credit. You can only win once on each individual line, however wins across several lines will be stacked together to form a total win.
Up Spinner Mini-Game
As your spinning through the neon jungle, make sure to look out for the green Bonus symbols. If you manage to spin in 3 or more Bonus symbols anywhere on screen, you’ll have just unlocked the Up Spinner mini-game. The more Bonus symbols you stacked up upon entry, the more spins you’ll receive in the mini-game, and the bigger the multiplier prizes will be.
Line up 3, 4 or 5 Bonus symbols and you’ll pick up 6, 8 or 10 spins in the mini-game. With your spins in hand, it’s time to face the Up Spinner wheel, which is filled with multiplier prizes. Each time you spin, you’ll be awarded the multiplier that you land on – but it doesn’t stop there!
Each segment you land on will then be upgraded to an even bigger multiplier for you to have the chance at spinning in. So you could leave this mini-game having stacked up some serious wins!
You’ll be delighted to know that in this mini-game you’re guaranteed a win, and after completing all your spins, you’ll head back to the main reels with any winnings having been already added to your in-game credit.
Wild Symbol
The odds could soon be stacked in your favour if you see the neon lights of the Wild symbol spin in on your reels. The Wild symbol has the power to try and light up a wondrous win for you, by having the ability to transform into every other symbol on your reels, apart from Free Spins and the Mini-Game.
For example, if you were to spin in 2 Diamond symbols on a win line, then you’d have just missed out on being dealt a win. However if there’s a Wild symbol next to them on the win line, it will take the place of a 3rd Diamond symbol to hand you a multiplier prize – what a gem!
Although this symbol is pretty electric, it can’t stack up the progressive Mega Jackpot for you. To spin in that prize, you’ll need to line up all 5 Jackpot symbols on a win line. Don’t worry though, when a Wild is combined with Jackpot symbols on a win line, this pair can create a multiplier prize light show!
Free Spins
You could soon be spinning in winnings if you find 3, 4 or 5 Free Spins symbols anywhere on your screen, as you’ll have just stacked up 5, 7 or 9 free spins respectively.
These free spins are locked to the value of your last paid spin, but don’t worry, nothing will be spinning out of your in-game credit, as these spins are free of charge, they’re on the house.
Once you’ve used up all your free spins you’ll head back to the main reels to continue stacking up those wins, with any prizes being automatically 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.
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 £100,000, 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.
