Shamrock Miner is an online slots game developed by Play’n GO. It has a lucky Irish theme and is played on 5x4 reels with between 12 and 27 paylines on which to land winning combinations. 

Free spins are one of the bonus features this slot machine offers. There are also cash symbols and expanding reels, which this Shamrock Miner slot review will explain later.

There are nine regular symbols, four high-paying and five low-paying. The high-paying symbols are the red, green, purple and yellow gems, while the low-paying symbols are the classic playing cards from ten to ace. Special symbols include the wild leprechaun, the scatter dynamite, and the cash gem. The wild will substitute for any regular symbol and also acts as a cash collector symbol. In this slot, the scatter symbol acts as the gateway to the free spins round.

Theme, graphics & soundtrack 

This Shamrock Miner slot offers a fun if not a very unique take on the ever-popular leprechaun-style slot. We see all the usual imagery, such as the shamrock, the leprechaun, and the Emerald Isle-style background. A nice amount of animation brings movement into the theme, such as when the wild symbols collect the gems from the cash symbols and transport them into the minecart. As we play, the soft and traditional Irish musical accompaniment sounds very similar to that of other Irish-themed free slot games.

Shamrock Miner bonus features 

As online slots go, this one offers some fun bonus features. 

Cash symbols

Cash symbols feature a rock with gems embedded and a cash value. These are collected by the wild symbol, which adds the gems to the minecart above the board. For every four gems in the cart, 10 free spins and an increasing random multiplier of up to 30x are awarded; what’s more, the reels will expand in height by one row up to a maximum of seven rows. This is the expanding reels feature and is how the 12 initial paylines can be increased to 27.

Free spins

The free spins can be accessed by landing scatter symbols: 3 scatters award 10 free spins, 4 award 15 free spins, and 5 award 20 free spins. During the free spins, wilds can land at the same time as the cash symbols with multipliers of up to 30x.

Overall Shamrock Miner review: our verdict

Shamrock Miner is a fun-to-play slot machine that lovers of the leprechaun theme are bound to enjoy. We love the bonus features and think the cheeky-looking leprechaun is a bit of a character. That said, we are not too keen on there only being 12 paylines to start off with in the base game and the maximum win of 5,000x is a bit low compared with some other online slots. Players can try the Space Stacks slot for something a bit different.
