The title of this slot — Stacks O’ Gold — is a dead giveaway as to what you can expect from this game by iSoftBet. You are going to be summoning up all the Irish luck you can and try to find some treasure at the end of the rainbow. Kidding aside, this game is a five-reel, 34-payline slot that comes with expanding wilds and a free spins round where up to three reels can turn into sticky wilds.

This game is inspired by the old, well-known myth that speaks of a pot of gold at the end of the rainbow. But instead of featuring leprechauns and rainbows, this slot goes ahead and puts on display all the things you’d expect to see around St. Paddy’s Day. Thus, on the screen, you’ll find images of Guinness pints, leprechaun hats, horseshoes, and four-leaf clovers, which makes this slot one ideal game to play when it’s time to celebrate the holiday. A small leprechaun village can also be seen, but none of the mischievous little creatures will make an appearance during your slot session.

Apart from its eccentric symbols and the crisp animations, another thing that makes this slot machine rise above the rest is the screen format. Namely, the Stacks O’ Gold features the standard five reels but the rows of symbols alter between each reel, beginning with three rows at the leftmost reel and then moving on with 4, 3, 4, and 3 again at the final reel.

Across this changing number of rows, you’ll be able to initiate payouts on 34 different paylines as well as win free spins rounds with a special stacked wild bonus that is awarded in three stages.

Some Irish-themed slots end up trying to do too much. However, the design in Stacks O’ Gold is actually more on the muted side. The glossy visuals are well done and there’s a gentle soundtrack that involves a harp playing in the background. The sound and imagery is gentle, but don’t be deceived; Stacks O’ Gold is as volatile as they come!


There is a gentle rural scene that forms the backdrop to the reels here. You’ll see bronze, silver and gold coins aside from horse shoes, pints of stout and green top hats. What you should always look out for from the standard symbols is the gold four-leaf clover, which will get you 1, 2 or 10 times your stake if you land 3, 4 or 5 in combination. The pot of gold is the wild. It doesn’t offer any payouts on its own but it takes the place of all other symbols bar the bonus whenever it lands. There are two main extras on offer in Stacks O’ Gold.


Free Spins

Land the bonus (the Stacks O’ Gold symbol) on reels one, three and five and you’ll be awarded 15 free spins. Each time one hits, it’s collected in a meter. Once you have six of them, you’ll receive two extra free spins and reel one will turn into a sticky wild and remain that way for the rest of the feature. Collect another 10 wilds and reel three turns into a sticky wild reel too and another two free spins are added to your tally.

Sticky Stacked Wilds Reels

If you’re lucky enough to find another 10 wilds on reels two, four and five, then reel five becomes wild and one more free spin is added to your total. This is known as the Sticky Stacked Wilds Reels feature. Special Golden Wilds can trigger at random at the beginning of any free spin too. They can turn the whole of reels one, three or five wild for the free spin that follows.
