Coin UP: Lightning

Coin UP: Lightning is a 3x3 slot machine from 3 Oaks Gaming, released in July 2024. The game uses a three-reel layout with an active line system and a lightning-themed presentation. Players can open the demo version to play for free and practice before playing for real money.

The main feature is a hold-and-respin Bonus Game, triggered when three symbols land on an active line. It starts with three respins, which reset when new qualifying symbols appear. The game includes BONUS SYMBOLS with MINI, MINOR, MAJOR and GRAND values, along with MYSTERY SYMBOL, MYSTERY JACKPOT SYMBOL and COLLECT SYMBOL mechanics. The bonus area can also fill completely to award the GRAND JACKPOT.

Additional features include COIN UP, SUPER COIN UP, MULTI UP and SUPER MULTI UP symbols, which can upgrade or multiply values in the bonus round. Sticky Coin, Sticky Jackpot Symbol and Sticky Mystery Jackpot Symbol may remain on the grid until the bonus triggers. An Ultra Bonus Game and Thunder Bonus Game are also listed among the special features.
