How to play

The Wild can subs
titute for other symbols to help complete winning combos. In this game, it substitutes for all symbols except the Free Spins Scatter symbol and the Level Up Scatter symbol.

Free Spins Scatter Symbol

If 3 or more Scatter symbols land on your reels, the Free Spins bonus will be activated, like so:

• 3 Free Spins symbols = 8 Free Spins
• 4 Free Spins symbols = 10 Free Spins
• 5 Free Spins symbols = 12 Free Spins

Before the first Free Spin a fixed Wild is placed on the central position on the reels (3rd reel, 2nd row). Free Spins start with Level 1. During Free Spins, the Level Up Scatter symbol can appear on slot reels 1 or 5. If it appears, it will increase the Free Spins Level by 1, up to the maximum of 5. The Level Up Scatter Symbol does not appear in Level 5. With each gained level, a Fixed Wild Symbol will be placed randomly on reels 2-4, directly adjacent to the initial fixed wild. The other wilds that appear during this feature do not remain fixed/sticky for the entire Bonus. During Free Spins, additional Free Spins will be awarded as long as a Level Up is triggered by a Level Up Scatter Symbol on the then-last Free Spin.

Energy Burst Feature

As soon as 3 similar symbols (except Wild Symbols and Free Spins Scatter Symbols) appear on the 3rd slot reel, the Energy Burst Feature is activated and Bonus Spins with 1 out of 3 Bonus Features (Exploding Wilds, Reel Clone or Wild Substitution) will be triggered randomly. Lower symbols (Jack, Queen, King and Ace) generate 3 Bonus Spins. High symbols (Capacitor, Goggles and Watch) generate 5 Bonus Spins.

Energy Burst I - Exploding Wild

After the Energy Burst Feature has been triggered, 2 or 3 randomly selected symbols on the display will be substituted by Fixed Wild Symbols. The Bonus Spins will start. During Bonus Spins the Fixed Wild Symbols remain at the display. The other wilds that appear during this feature do not remain fixed/sticky for the entire Bonus/Free Spins.

Energy Burst II - Wild Substitution

After the Energy Burst Feature has been triggered, a randomly selected symbol (Ace, Capacitor or Goggles) will be chosen. If the selected symbol appears on the display during Bonus Spins, it will be converted into a Wild Symbol.

Energy Burst III - Reel Clone

After the Energy Burst Feature has been triggered, 3 randomly selected reels (1-2-4, 1-3-4 or 2-3-4) are linked so that they always have the same symbol arrangement on the display. The linked reels remain the same for all Bonus Spins.

Return to player

This game has a theoretical RTP of 96.20%, which means for every £100 staked, the expected return would be £96.20.
