Book of Blarney Gigablox Bonus Rounds & Free Spins

Book of Blarney Gigablox has 3 Bonus rounds up for grabs, triggered when 6 or more Book Scatters land during the base game. Once active, Free Spins, Lucky Coins, or the Water Wheel bonus is awarded at random.

Water Wheel Bonus

When the Water Wheel bonus is active, the number of triggering Scatters equals the number of Spins awarded. At the start of the round, you are given a choice between 2 Multiplier Wheels, each varying in Volatility.

On each spin, a Mushroom is to be selected to reveal a Cash Prize. Your chosen Water Wheel will spin, and a Multiplier value will be selected. The two values are then multiplied together to add to the accumulating win.

Lucky Coins Bonus

Upon entry into the Lucky Coins bonus, each triggering Scatter will transform into a special Coin symbol that rotates to reveal a Cash Prize or Pot name. Larger Scatters transform into bigger Coins with on average larger rewards.

Each Coin symbol will lock into position, and 3 Lives are granted. Positions that do not have Coins will spin and result in either a Blank or a new Coin. Each spin deducts a life, however, each new Coin will reset the Lives back to 3. Filling the entire grid with Coins will automatically award the Mega Pot which is added to the accumulated values in view.

Free Spins

When the Free Spins round has been awarded, the number of triggering Scatters equals the number of starting Free Spins. Each winning spin will award an additional +2 Free Spins, up to a maximum of 8.

In the spin following a win, the reels will expand by +1 row, adding 15 additional pay lines into the mix, up to a maximum of 8 rows and 100 pay lines.

Pros and Cons of Book of Blarney Gigablox


  • Lucky Bet and Bonus Buy options.
  • Variety of Bonus rounds.
  • Multiple betting options, above-average RTP, and generous max win cap of 10,368x.


  • Overused Irish theme.
  • When the Bonus is triggered, you don’t get a choice in which Bonus round is awarded.
  • Lack of base game features.


The Gigablox feature has substantially enhanced the appeal of many a game before Book of Blarney, and we can see how those with a soft spot for the green hills of Ireland might find appeal in Reflex Gaming’s offering.

However, we do have some complaints. Book of Blarney offers 3 different bonus rounds, all of which are triggered by landing 6 or more Book symbols in view. In our opinion, the Water Wheel and Lucky Coins feature may have been better as random modifiers instead, considering neither of them is as exciting as the actual Free Spins round.

Nonetheless, the Water Wheel and Lucky Coin features have potential, and this is especially true of the Lucky Coins feature where the Jackpots are a possibility.

At its best, Book of Blarney is supposedly capable of up to 10,368x the bet. This is appealing and in line with many other games out at the moment, but we’re unsure of how possible it really is in a non-simulated spin.

Overall, Book of Blarney isn’t the best Irish or even Gigablox game, but we can see the potential, and we understand the appeal.
