The moment you load Coin Up: Lightning at 666 Casino, you’ll notice the crisp artwork and attention to detail. Storm clouds gather over the 5 reels, ready to strike the 25 paylines with bolts of lightning. The background scene immerses you in the heart of the storm with flashes of light and rumbles of thunder. It’s enough to make your heart race with anticipation!

Winning Lines

Coin Up: Lightning features 25 fixed paylines that pay out wins from left to right. Since all lines are permanently enabled, you just need to set your bet per line ranging from £0.01 up to £20. This makes the minimum bet £0.25 and the maximum £500 per spin. Landing 3 to 5 matching symbols on adjacent reels from left to right across an active payline triggers a payout based on the symbol value. The lightning wild can substitute for other symbols to complete winning combinations. With each spin, you have a chance to win up to 5,000x your line bet if you land 5 wild symbols on an active payline!

Bonus Rounds

The Coin Up: Lightning slot has two bonus features that can lead to huge payouts:

1. Lightning Spins: This bonus round activates when a full reel wild lands. You’ll receive 5 free spins with a 2x multiplier on all payouts. If you fill another reel with wilds during the Lightning Spins, you get 5 more spins and the multiplier increases to 3x. This continues increasing the multiplier up to a maximum of 10x over multiple rounds!
2. Coin Up Bonus: Landing 3 or more scatters triggers the Coin Up bonus. You’ll pick from rows of coins to reveal instant credit prizes or extra spins. During the bonus game, all coin values increase after each pick, and you can also win additional picks. With multipliers reaching up to 88x, this round can payout massive wins!
