How to Play Stack Spin Win

Playing on Mr Spin is as easy as Stack, Spin, Win! As this game is locked to 20 win lines, all you will need to do is set your total bet. To do this, you will need to tap the ‘Bet’ button and use the ‘+’ and ‘-‘  buttons to adjust you bet-per-line accordingly. This number will always be multiplied by 20 win lines , and you can see your total bet update automatically.

For example, if you bet 20p per line on these rockin’ reels, then your total bet will be £4.00. You can bet a minimum of 1p and a maximum of £10 per line. When you’re ready to roll, all you need to do is just tap the spin button to play.

Reel Wins

Now that you’re ready to stack ‘em up and spin em’ round, how will you know if you’ve got that all important win? Don’t forget that any wins are a multiplier of your bet-per-line and depend on the symbols that you spin in. To shuffle in a win, you will need at least 3 symbols lined up together on an active win line and win lines always pay from left to right.

You can only win once on each individual line, but if you spin in some luck and win across several win lines, these will get added together to create a total win! Any winning lines will be highlighted on screen and will be added to your credit automatically!

If you want to stack up on all the win information, this can be found in the ‘Paytable’. To locate this just press the menu button in the top left-hand corner and then ‘Paytable’.

Wild Symbols

As you’re spinning on the reels of Stack Spin Win, keep a close eye out for the wickedly wonderful Wild symbols! If you see these appear in your win lines, you might be in for a big win; that’s because this symbol substitutes for any other on the reels, except for Free Spins and mini-game symbols.

So, for example, if you spin in 3 heart symbols on a win line then that’s already a stackingly good win, but if there’s a Wild symbol next to it, the win spins into that of 4 hearts!

The Wild symbol is a jack of most trades, however, there are a few things that it simply cannot do! You can’t win the Mega Jackpot with a Wild on your winning line, the only way to win this is by spinning in 5 Jackpot symbols on a win line. If you do spin in a combination of Jackpot symbols and a Wild though, that will still be a classic win!


To enter the Up Spinner mini-game, you will need to spin in 3 or more Bonus symbols anywhere on screen. The more symbols you spin into the mini-game with, the more free spins you will receive! Line up 3, 4 or 5 Bonus symbols and you will get 6, 8 or 10 spins in the mini-game, respectively.

Grab your spins and it’s time to face the Up Spinner wheel, filled with mega multipliers just waiting to be won! Once you’ve spun the wheel for the first time, you’ll win the multiplier you landed on—but wait, it gets better! The segment will then be upgraded to an even bigger multiplier for you to possibly land on, so you could walk away from this mini-game having stacked up some serious wins!

After completing all of your spins you will return back to the reels with you latest prize added to your credit! This is no joker, in this mini-game there’s always a guaranteed win!

Free Spins

You’re sure to be glowing if you see our Free Spins symbols spin in on your reels! If you line up 3, 4 or 5 Free Spins symbols anywhere on screen, you’ll receive 5,7 or 9 free spins respectively!

Your free spins are locked to the value of your last paid for spin, but don’t worry as you’ve been such a diamond you won’t be charged for these spins, they’re stacked on the house!

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 £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.
