Visually, Firefly Frenzy is stunning – set in a mysterious world, it comes with 4 gleaming crystal symbols (representing clubs, diamonds, hearts and spades). You’ll also see 4 mysterious flora symbols – the golden one is the most rewarding giving you 3, 15 or 30 times your stake for 3, 4 or 5 in combination.

Central to the action is the green/yellowish Firefly wild which replaces all symbols bar the moon scatter – paying like the most valuable symbol, they can land on all reels. They can appear as a standard wild, 2x multiplier wild (orange/yellow in colour) or 3x multiplier wild (pink). If you get more than 1 multiplier wild, the values are multiplied together giving you a potential 243x multiplier:

  • Two 3x multiplier wilds = 9x (3x3)
  • Three 3x multiplier wilds = 27x (3x3x3)
  • Four 3x multiplier wilds = 81x (3x3x3x3)
  • Five 3x multiplier wilds – 243x (3x3x3x3x3)

There’s also the moon symbol which is the scatter – only 1 of them can appear on each spin. When it appears, a Firefly wild lands on it to give you access to the Frenzy Spins feature. With 8 free spins awarded, the value of the multiplier wild will be the lowest multiplier that lands during the feature.

For example, if you triggered the Frenzy Spins feature with a 3x multiplier wild, all multiplier wilds appearing during the feature will be 3x. If you activated the feature with a 2x multiplier wild, the multiplier wilds will be either 2x or 3x. This dramatically increases your chances of winning big during these free spins. Finally, you can retrigger the feature with a possible 16 free spins in total.

Firefly Frenzy may look mysterious and soothing but it’s a highly volatile slot – it’s all about the Firefly wilds appearing on multiple reels for big multipliers up to 243x. I like the fact the Frenzy Spins feature can guarantee Firefly wilds are of a certain value – the key to winning big is to trigger with 2x or 3x multiplier wilds.

Anyway, you can win a cool 10,000 times your stake on each spin or free spin. Overall, Firefly Frenzy is a fiery slot which is all about the wild multipliers. I also recommend you try Play ‘N Go’s Crystal Sun which is another game focused on multipliers.
