About Thunder Coins XXL: BoosterCells
Thunder Coins XXL: BoosterCells gives Playson's Thunder Coins series a new bonus mechanic, on a 3 × 5 grid with 15 lines. Four jackpots, Mini, Minor, Major and Grand, are always in play, and their Jackpot Coins can land at any moment.
Inside Thunder Coins XXL: BoosterCells
Getting into the bonus
Coins on reels one and three with a Thunder Coin on reel two start the Bonus Game. Pile of Gold can also step in at random when any Coin lands, adding enough Coins and Thunder Coins to trigger it.
Cells that store value
Inside the bonus, every collected Coin value is stored on its cell. When another Coin lands on a stored cell, the two values combine, so a single position can keep building through the whole round.
Sticky Thunder Coins
Thunder Coins land on reel two and stick for the whole feature. Each one collects the values of every Coin on the reels, and each new one may randomly boost the values stored in the cells.
Thunder Coins XXL: BoosterCells questions
What happens when a Thunder Coin lands in the main game?
If it lands alongside any Coin, the Thunder Feature collects all Coin values in play, including any Jackpot Coin, and adds them to that spin's win.
Can I start with Thunder Coins already in place?
Yes. The Super Buy Bonus guarantees three active Thunder Coins, while the regular Buy Bonus lets you pay to open the Bonus Game straight away.
