Book of Blarney Gigablox Slot Review

Irish-themed slots have been vintage in style for quite a long time. But things have changed in the past few years thanks to developers such as Reflex Gaming, who have taken this slot niche in a completely new direction. Book of Blarney Gigablox was developed for Yggdrasil, bringing a fun new mechanic to a familiar bonus theme.

This isn’t your typical Irish-themed leprechaun slot. Instead, the 40-payline slot game with medium to high variance mostly relies on gigantic symbols with powerful modifiers in the mix as well. The slot’s winning potential is off the charts, too, and the fact you’re getting almost triple the number of lines in the bonus round makes it as exciting as it gets.

It’s also pretty fun to see Blarney, the leprechaun, sprinkling his magic from the right side. The design of the symbols and the video slot overall looks fantastic. To learn more about it, read my Book of Blarney Gigablox slot review below.

Book of Blarney Gigablox Slot Layout, Theme, and Setup

Irish-themed slots most often look the same. Book of Blarney Gigablox doesn’t stray too far from the path but comes with sharp graphics and great animations. The controls are beneath the reels, as mentioned, so they’re easy to access on any device, desktop, and mobile included. Blarney, the leprechaun, overlooks the action from the right side, sprinkling the reels with his magic dust for juicier wins.

The background shows a green meadow, which is somewhat generic for these slots. The symbols are also Irish in theme, including stylized card royals, a horseshoe, a gold pot, and the leprechaun’s hat.

They were all decently rewarding, although I didn’t hit the jackpots or any ground-breaking wins.

How to Play Book of Blarney Gigablox Slot

Playing the Book of Blarney Gigablox slot is easy despite the fact you’ll see giga-sized symbols occupying several reels. The minimum bet is just 20c, while the maximum is $100. Choose what suits you best and hit the Spin button to start playing.

When the 6x4 reel set turns, you might stumble across gigablox symbols that can land as 1x1 or bigger in size. They may even cover an area of 6x6, although that’s less likely. A beer mug is the wild, and it can substitute for other symbols in winning combinations while linking wins. It’s also the highest-paying symbol on the paytable.

There aren’t many special features except for the Gigablox symbols in the base game. Luckily, the slot does great with the addition of three bonus rounds, all of which are activated in the same way.

Book of Blarney Gigablox Slot Free Spins, Bonus Features & Bonus Buy

The Book of Blarney Gigablox online slot has three bonus rounds. You need six books to trigger a random feature, each one with its unique modifiers.

  • Water Wheels: you get as many spins on the water wheels as the number of triggering scatters. Before you start, you can choose lower or higher volatility, both of which offer multipliers. The former pays a maximum of x4, while the latter pays a maximum of x10.
  • Lucky Coins: a classic Hold & Win bonus round with 3 respins. Only coins with values can land on the reels, with each one resetting the respins tally back to 3. This is the way you can win one of the four jackpots when the respective coins land on the reels. 2x coins double the initial values.
  • Free Spins: each win in the bonus round expands the grid by 1 row and the paylines by 15. The maximum is 100 paylines on an 8x6 grid. Each win awards a pair of spins.

My Experience Playing the Book of Blarney Gigablox Slot for Real Money

I love Gigablox slots, so it was only a matter of time before I tried the Book of Blarney Gigablox slot for real money. It didn’t disappoint, thanks to the medium variance and a few decent wins with the giga-sized symbols. I had to try the Water Wheels and Lucky Coins features via the buy bonus slots feature, but I managed to land the free spins round naturally.

They were all decently rewarding, although I didn’t hit the jackpots or any ground-breaking wins. But it was a fine ride overall and will certainly impress players of the Irish or Gigablox niche.

Book of Blarney Gigablox Slot Verdict and Recommended Games

Book of Blarney Gigablox brings giga-sized symbols into a familiar mold with great results. That is if you count the three bonus rounds. The base game can be a bit stale if you don’t land giga symbols often, which might disappoint some players. That being said, the bonuses themselves are very exciting. You trigger any randomly by landing six coins, or you can try them via the bonus buy feature as I did. Either way, they ended up pretty fun, so I’m not against spending a bit more money to get them. You’ll most likely earn at least the same in return.

If you’re looking for a bit more vintage leprechaun action at top casinos, there are plenty of options. 4ThePlayer’s 3 Lucky Leprechauns is a good choice, as is Play'n GO’s Leprechaun's Vault. Almost all developers have one kind of Irish slot or another, so you won’t find it hard to try and see if you have the luck of the Irish.
