Auto-Play and Turbo Mode

If you just want to lean back and have fun, switch on Auto-Play mode. Let this retro vibe handle the rest.

 

And don’t hesitate to try Turbo Mode across three distinct speed tiers and experience the lightning-fast action unfolding in the blink of an eye.

 

Special Symbols

Image

Low symbols

 

Oranges, lemons, plums, and cherries will pop up the most across the reels. This juicy fruit mix helps form winning combinations and puts a sweet multiplier at the end.

 

Image

Medium symbols


Want to make life even sweeter? Try to catch watermelons and grapes. Their multipliers will take your round to a whole new level.

 

Image

High symbols

 

The action doesn’t stop there. Catch the Golden Bell and BAR symbols across the reels, and you’ll know Lady Luck is truly smiling on you.

Image

Wild symbol

 

How could we forget the legendary Lucky 7? Acting as the Wild, it substitutes for other symbols (except Feature, Jackpot, and Boost) to form your winning combination when you least expect it.

 

Image

Boost Symbol

 

Boost symbol supercharges the reels. Whenever it lands alongside Jackpot or Feature symbols, it ramps their value right up to x5.

 

Image

Regular Coin Symbol

 

Those shiny gold coins look great, but wait until you land six of them with a Boost or Jackpot. It instantly unlocks the portal to the Feature Game.

 

Image

Jackpot symbols

 

During your session, keep your eyes glued to the Mini, Minor, and Major Jackpot symbols. This is where the magic happens, handing you prizes up to 100x your play size.

 

Image

Multiplier

 

To keep the action truly electric, Multipliers can drop in out of nowhere at any point during the Feature Game. These symbols prove that classic reels still know how to blow you away.

 

Bonus game

Image

The energy hits its peak in the Feature Game! You start with 3 re-spins that reset every time a fresh symbol drops onto the grid. The action keeps roaring as long as you keep landing Coin symbols, Jackpots, and Multipliers.
Simple mechanics, but effective spectacle.

 

Special Features

Image

Extra feature game

 

Any Feature, Jackpot, or Boost symbol landing during the regular game brings a random chance to charge up the Extra Feature Game. When it strikes, the reels drop extra bonus symbols across the screen, instantly powering your way into the main Feature Game.

 

Image

Boost feature

 

The Boost symbol is a true MVP, tackling several key roles all in a single game:

 

  • Instantly collects and multiplies all visible Feature and Jackpot values.

  • Also multiplies Feature, Jackpot, and Boost symbols values in Feature Game.

  • This feature can boost your wins by up to x5.

  • But it doesn’t multiply unrevealed Boost symbols values.

 

Image

Play Feature

 

No time to wait and want that bonus thrill right now? Play Feature has you covered. Hit the button on the main screen, pick between two bonus modes, and instantly dive into what keeps players coming back to Grand Lightning Boost.

 

Image

Jackpot feature

 

Jackpots deliver the highest rewards, boosting your prizes by up to 100x. Think that's everything? There's still another ace hidden up this sleeve.

 

Image

Grand Progress feature

 

Complete a 3-symbol column in the Feature game and there's a chance to reveal a letter. Collect them all to form the word GRAND, unlocking a colossal Jackpot that grants up to x1000x your play size.

 

Image

Multiplier Feature

 

There’s truly no limit to the rewards. Catch Multiplier symbols, and suddenly, some other symbols on screen give rewards way beyond your expectations.

Take a spin and discover the power waiting behind this retro lightning.
