Shamrock Miner Review

New from Play’n GO, Shamrock Miner is a vibrant Irish-themed online slot that has players digging for precious diamonds as opposed to hunting for that elusive pot of gold that lies at the end of the rainbow. Dig deep and help the lucky leprechaun uncover a haul of gemstones and, in turn, he’ll reward you with valuable cash prizes.

The initial gameplay unfolds across a 5×4 reel layout, where you’ll earn standard payouts whenever 3 or more matching symbols land across any of the 12 available paylines. Special cash symbols and wild multipliers can also generate instant wins throughout the base game, while dynamite Scatters unlock the game’s true potential courtesy of a free spins bonus that boasts progressive win multipliers and expanding reels.

So, grab your mining gear and prepare to travel beneath the Earth’s surface for a chance to discover the vast riches that lie beneath. But first, read our Shamrock Miner slot review to familiarise yourself with this game’s features and mechanics.

Shamrock Miner Bonus Features

Diamonds are key to big wins in Shamrock Miner, so be sure to look out for special cash symbols appearing throughout both the base game and the free spins bonus round. Plus, whenever special Wild Multipliers land alongside, you’ll be in store for even larger payouts. You’ll also want to prepare for detonation whenever three or more dynamite Scatters land during a single spin, These will grant access to the free spins feature where a progressive collection feature can unlock some seriously valuable multipliers. Let’s take a more in-depth look at how these features work:


The titular Leprechaun Wild plays a huge role in Shamrock Miner. Not only does it act as a substitute for all regular symbols to improve your chances of creating winning combinations but it also has a few other special tricks up its sleeve when it lands alongside diamond cash symbols.

Cash Symbols

Diamonds can appear on any of the five reels, each displaying various cash values worth up to 50x your stake. Although these don’t trigger a payout when landing on their own, any Wild symbol that lands during the same spin will collect all of the diamonds on screen and award their collective values. Plus, on any spin, a random multiplier between 1x-10x can appear above the reels. So, if the lucky Leprechaun’s feeling particularly generous, these precious gemstones can become much more valuable than ever before!

Scatter Symbol

Appearing as dynamite sticks, Scatters can land on each of the five reels. You’ll need at least 3 to trigger the free spins feature but the more that you land, the more free spins you’ll receive, as outlined below:

  • 3 Scatters: 10 free spins
  • 4 Scatters: 15 free spins
  • 5 Scatters: 20 free spins

Free Spins

After detonating enough bundles of dynamite the real diamond mining begins. During free spins, Wilds and cash symbols are key to your progression. Like in the base game, each Wild will collect the values of all visible cash symbols and instantly award their collective worth. Now, however, whenever a Wild lands, it itself is also collected by mining carts sitting above the reels. Every fourth Wild you collect will retrigger the bonus. This awards +10 free spins, increases the random multiplier values up to 30x and also expands the reels by +1 row up to a maximum height of 7.

Shamrock Miner Jackpot

Shamrock Miner doesn’t come with a traditional progressive jackpot. However, if you’re able to unearth enough diamonds, a potential reward worth up to 5,000x your stake awaits at the end of the rainbow.

RTP and Volatility

Featuring medium to high volatility gameplay, Shamrock Miner offers reasonable levels of risk versus potential reward. It also comes with a competitive default RTP of 96.29% but you should beware of the customisable RTP settings for this game – check the available RTP at your chosen casino before playing.
