How to Play Big Irish Bucks Online Slots

Before you start spinning, you’ll need to set a total bet. You can do this by clicking the ‘Bet’ menu in the bottom left corner of your screen and clicking the +/- buttons to adjust your bet per line. Your total bet is calculated by multiplying your chosen bet per line by the number of active win lines.

In Big Irish bucks, there are 15-win lines, with the minimum bet-per-line being 1p and the maximum being £2 per line. For example, if you set your bet-per-line to £1, your total bet per spin would be £1 x 15 win lines = £15.

You’re all set, get spinning!

Reel Wins

Once you’ve started spinning, you’ll want to know how to win BIG! Just click the spin arrow and the reels will be on their way, stopping at random. You’ll know you’ve spun a win because all winning combinations light up and the win amount will be automatically added to your credit.

The value of your wins will depend on what you spin-in and how many of that symbol there are, but you’ll need at least 3 matching symbols to catch a win! All Big Irish Bucks wins work from left to right. You can only win once on an individual line but wins across several lines can be added together to give you one Big Bucks Win.

Consult the ‘Paytable’ in the top-left of the screen to see what the symbols are valued at, and to learn more about the game’s features.

Wild Symbols

Wilds are exactly that: WILD!! Keep your eye out for these magical Leprechauns, they hold the power to replace every symbol on the reel except for Free Spins.

For example, if you were to spin in 2 Heart symbols, you’d have been so close to scoring a win… if there’s a wild symbol next to it, this will act as the third Heart, giving you a win of x8 your multiplier.

To win the Progressive Jackpot you’ll need to spin all 5 jackpot symbols but a combination of Wild and Jackpot Symbols could see you still winning some Big Bucks.

Free Spins

If you manage to spin 3, 4 or 5 Free Spins symbols anywhere on your reels, you’ll be rewarded with 5, 7 or 9 Free Spins respectively.

Consider these as a free gift from your Leprechaun friend. You won’t be charged for Free Spins.

All Free Spins are based on your bet per line from your last paid spin. Once all your Free Spins have been taken, winnings will be added to your pot automatically before returning to the reels.

But that’s not the best part of Free Spins… It can activate the Golden Plates Mini-Game.

Golden Plates Mini-Game

While in Free Spins mode, Golden Plates will be added to the reels, which can lock in some massive multipliers!

If you spin 3 ‘Lock Symbols’ anywhere on the reels, all other wins are awarded and everything but the Golden Plates will re-spin for free (not even using your free spins)! The reels will then spin again whilst the lock symbols remain in place. If you spin even more lock symbols, then these will remain stuck on the reels as you spin again.

The reels will continue to spin until no more Lock symbols are spun in or the reels are fully loaded with Lock symbols! When this happens, the feature game will end, and any winning lines you have will be paid out for a potentially huge prize!

When you activate this golden feature, all other symbols will be out of play. But fear not, any extra Spins you receive to see if any more Lock Symbols appear will not be taken from you! Essentially, you’ll have Free Spins within Free Spins!

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.
