How to Play Big Irish Bucks Online Slots

Before you can search for that pot of gold, you’ll need to set your total bet. This is calculated by multiplying your bet-per-line amount by your chosen number of active win lines. In Big Irish Bucks, win lines are locked to 15 and you can bet between 1p and £2 per line.

Tap the Bet menu in the bottom left of the screen and use the ‘+’ and ‘-‘ buttons to adjust these values. For example, if you were to set your bet-per-line to 10p, your total bet would be £1.50 per spin.

Once you’re ready, simply tap the spin button.

Reel Wins

On the bright lights of these slots, all wins are a multiplier of your bet-per-line. The value of your win will depend on the type of symbols spun in and how many appear together on an active win line. You’ll need at least 3 matching symbols on a win line to score a win and be cl-over the moon.

To discover what exciting features this game has, be sure to visit the paytable located in the top-left corner of your screen. It’s here that you can also find out what symbols can be spun in, each multiplier value and which are the win lines.

All win lines on this glamourous game will pay from left to right across the reels. Any winning lines will be highlighted on screen and automatically added to your on-screen credit. You can only win once on each individual line, however, wins across several lines will be added together to form one shamrocking prize.

Wild Symbols

To add that little extra dash of magic, keep your eye out for the Lucky Leprechaun. He’s acting as your Wild symbol and has the power to take the place of every other symbol – except Free spins symbol.

For example, if you were to spin in 2 Gold Coin symbols on a win line, you’d have just been shy of winning a prize. However, if there’s a Wild symbol next to them on the win line, it will act as a third Gold Coin and you’ll be coining it in with a x10 multiplier!

Despite being a lucky charm, it cannot help you win the progressive Mega Jackpot. For you to win that mega pot of gold, you’ll need to spin in all five Jackpot symbols on an active win line. Don’t worry though, a combination of Wild and Jackpot symbols could still see you dancing a jig of delight.

Golden Plates Mini-Game

The Golden Plates Mini-Game is only accessible through Free Spins. Once you have spun in at least 3 Free Spins Symbols anywhere on screen, the reels will change and all Win symbols will turn into Lock symbols.

During your Free Spins, if 3 or more Lock symbols are spun in then these will stick on to the reels. The reels will then spin again with the Lock symbols remaining in place and if any new Lock symbols are spun in, these will remain stuck on the reels as they spin again.

This will continue until either no new Lock symbols are spun in, or the reels are filled with Lock symbols. At either of these points, the feature will come to an end and any winning lines you have that feature Lock symbols will be paid out for a potential huge golden prize!

All other symbols are out of play during the Golden Plates Mini-Game. The extra spins you receive to see if more Lock symbols appear on the reels won’t be taken from your Free Spins. That’s right, these are Free Spins within Free Spins!

Free Spins

You’ve got the luck of the Irish if you manage to spin in 3, 4 or 5 Free Spins symbols anywhere on the reels, as you’ll be rewarded with 5, 7 or 9 Free Spins respectively. As we’ve mentioned, it’s during Free Spins that you can activate the Golden Plates Mini-Game.

But don’t despair if you don’t manage to enter that golden feature, you could still pick up your own pot of gold here. Don’t forget, you won’t be charged for these spins, consider them a gift from the Lucky Leprechaun.

The bet-per-line amount from your last paid for spin will be used to calculate any winnings during Free Spins. Once all your Free Spins have been taken, any winnings will be automatically added to your on-screen credit before you return back to the main reels.

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.
