How the Game Plays

Developed by 3 Oaks Gaming (formerly Booongo), Coin Up: Lightning is a sleek, neon-drenched addition to the "Coin Up" series. Shifting away from traditional fruit machine tropes, this 3x3 slot eliminates regular paying symbols from the base game entirely. Instead, the focus is squarely on landing special Bonus and Coin symbols across the three active paylines. To trigger the central feature, you must align any three symbols on a payline. The game features Sticky Coins that remain on the grid until the bonus is activated, providing a head start on filling the reels.

Hold and Win Bonus Explained

The core of the experience is the Hold and Win bonus round, where the triggering symbols lock into place and three respins are awarded. Landing any new symbol resets the respin counter. Unique to this title is a special "Bonus Row" above the main 3x3 grid where Multi Up and Coin Up symbols appear. These modifiers apply multipliers or increase coin values for the specific reel below them, or the entire grid if the "Super" version lands.

Jackpots and Special Modifiers

Four fixed jackpots are available during the bonus: Mini, Minor, Major, and Grand. While individual coin values and the smaller jackpots appear frequently, the Grand Jackpot—worth 500x the stake—is awarded if all nine positions on the grid are filled. Mystery symbols and Mystery Jackpots add further unpredictability, transforming into high-value coins or jackpot prizes at the conclusion of the round. For those who prefer direct access, the game offers three Bonus Buy levels, including "Ultra" and "Thunder" options that guarantee starting modifiers.
