Take a journey to the jolly Emerald Isle ruled by playful leprechauns and try your best to unearth their gold with Stacks O' Gold slot machine, brought to you by iSoftBet. The incredible game draws inspiration from Irish culture and tradition, more precisely, 'the luck of the Irish'. The overall design and symbols reflect the theme featuring an idyllic, countryside landscape with a rainbow lurking behind the reels. The 2017 release comes with a free spins feature with additional Wild symbols, as well as the Sticky Stacked Wild Reels feature that can rack up some serious prizes along the way.
The Stacks O' Gold slot features a unique 5-reel set with a 3x4x3x4x3 row structure and 34 paylines. Before you step into the Leprechaun's Paradise, though, it's advisable to refer to the paytable by clicking on 'i' button and set your bet. The coin size ranges from $0.01 to $1.00, while the stake per spin can go anywhere from $0.20 up to a ceiling of only $20, which will satisfy the low-rolling punters. The Autoplay feature is also available and will come in handy if you want to spin the reels without interruption for a chosen number of times. Finally, Spin will set the reels in motion.
The symbols which populate the reels relate to Irish luck theme, so you will come across horseshoes, top hats, silver, gold and bronze coins, as well as pints of dark beer and golden four-leaf clovers, the latter being the most lucrative symbols on the reels, awarding 200 coins for five of them on a payline. Wilds are represented by a pot of gold and they can substitute for all other symbols to form a winning, apart from Bonus symbols, which are represented by the game's logo sign.
Land three Bonus symbols on the first, third, and fifth reel and you will trigger the Free Spins feature, awarding 15 free spins. Keep in mind that additional Wilds can pop up during the feature and once each of them lands on the reels, they will be collected in a meter. When you have collected six Wilds, you will win two additional free spins, whereas the reel one will become sticky and remain frozen for the duration of the feature, to boost your winning power.
If you manage to collect ten Wilds, the reel three will turn into a sticky Wild, too, and you will receive two additional spins. Should you land another ten Wilds on the second, fourth and fifth reel, the reel five will become sticky Wild, and you will be granted an extra free spin. The feature is called the Sticky Stacked Wild Reels feature. During this bonus round, golden Wilds can also pop up at random on the reel set, turning the entire reel 1, 3 and 5 wild for the duration of the feature.
Stacks O' Gold is a highly volatile video slot with an average return to player (RTP) of 96.17%. Speaking of the theme and bonuses, iSoftBet didn't present any breakthrough, however, the fast-paced gameplay will keep you entertained for the most part. On the other side, we must admit that the Free Spins feature is a bit hard to trigger, so be prepared for a number of dead spins before you can hit a bigger prize. Finally, the narrow betting range can only cater to the needs of low-rollers or simply those who enjoy Irish-themed slots.
