Coin Up: Lightning (3 Oaks Gaming (Booongo)) – Review & Demo Play

Introducing Coin Up: Lightning Slot

Coin Up: Lightning is a coin-themed slot on a tidy 3x3 grid with up to 3 active lines. You can choose how many lines to run and there are no regular symbols, only bonus types that do the heavy lifting. Land three symbols in a row on an active line to kick off the Bonus Game, where all landed bonus symbols stick and you start with 3 respins. New symbols top up the counter, except UP symbols, and filling all 9 spots pays a tidy prize.

Out on the main game, Sticky Coin symbols hang about and can pay up to 5x your bet, which nudges you closer to the feature. In the bonus, Coin UP and Multi UP sit above the reels and can ramp values or add multipliers. If I can’t be bothered waiting, I use the Buy feature to jump straight into the action at different levels. It’s a neat twist on Hold and Win with a punchy pace.

Theme & Design: Electrifying Gem Aesthetic in Coin Up: Lightning

This one’s a right-looker. The coin theme sits over deep blues with flashes of lightning that light up the screen. Colours are bold and in your face, coins sparkle, and the layout stays clean and modern so it’s easy to follow. The soundtrack keeps things lively enough for high-energy spinning, and those coin clinks add a bit of snap. Nothing overdone, just a sharp presentation that fits the quick fire gameplay.

Symbols & Payouts in Coin Up: Lightning

Symbols here are all special. Coins land with values between 1x and 5x the bet. Sticky Coins can settle in during the main game and stay put until the bonus, paying up to 5x and filling slots that help line up the trigger. Gold Jackpot Coins carry preset prizes. The Collect symbol grabs the values in view. Mystery symbols can change into any symbol except a Sticky Coin, while a Mystery Jackpot symbol becomes a Mini, Minor, or Major at the tally.

In the Bonus Game a top row appears for UP symbols. Coin UP raises coin values on the reel below, while Super Coin UP affects the whole grid. Multi UP adds multipliers to symbols on a reel and Super Multi UP applies across the board. These apply at the end, so building a screen with coins and jackpots before the count can pay nicely, especially when a Collect has tidied up the totals.

How to Play Coin Up: Lightning Slot Machine

Here’s how I get stuck in with Coin Up: Lightning. Set your bet with the coins button, from €0.10 up to €60. Pick 1, 2, or 3 lines. Hit Spin, or tap Enter or Space on desktop for standard spins, hold for turbo. Autoplay if you fancy letting it run. Pop open the menu button to check the paytable and rules. Quick spins and audio toggles sit there as well, so you can set the pace and just crack on.

Bonus Features in Coin Up: Lightning

The Sticky Coin feature shows up in the main game at random. When one lands, it sticks where it is until you hit the Bonus Game. Each can pay up to 5x your bet on the way, and the fact they sit there makes it easier to line up three bonus symbols on an active line. Simple idea, tidy effect, and you feel the grid priming itself for a burst.

Trigger the Bonus Game by landing three symbols in a row on any active line. The three that got you in lock in place, and you start with 3 respins. Every new bonus symbol that drops, except an UP symbol, resets the counter back to 3. You keep going until you run out of respins, or all 9 positions fill up with bonus symbols. Coins in the feature carry values from 1x to 5x the bet.

During the Bonus Game a top row spins UP symbols that influence reels below. Coin UP and its super version ramp coin values, while Multi UP and Super Multi UP add multipliers that apply at the end. Mystery can reveal any symbol except a Sticky Coin, and Mystery Jackpot turns into Mini 10x, Minor 20x, or Major 50x. Fill the grid for the Grand 500x. If patience runs thin, the Buy options are there at 30x, 75x, or 150x to start with extra kickers.

Max Win, RTP, & Variance in Coin Up: Lightning

Numbers wise, Coin Up: Lightning tops out at 500x your bet via the Grand if you fill the grid. The RTP sits at 95.67%, a shade under the going rate, but the flow feels fair enough with the way bonuses pop. Volatility lands around medium on my sessions, so balance is the word here, with a steady rhythm of features when all three lines are active. It’s a pacey Hold and Win style loop with clear ceilings.

Verdict for Coin Up: Lightning Online Slot

I rate Coin Up: Lightning as a tidy little earner for quick sessions. The bonus round triggers often enough, especially with all 3 lines on, and the modifiers stack in a way that feels busy without being fiddly. Sticky Coins do their bit setting up the feature, and the Buy route is convenient when I want straight action. Four jackpots in play keep the tally interesting, even if the ceiling is modest.

The cap at 500x and the 95.67% RTP won’t lure every high roller, but the gameplay stays simple, punchy, and newbie-friendly. I like the clean loop, I like the way UP symbols shape the end tally, and I’ve had tidy runs when Collect lands late. If you fancy fast-paced action with clear rules and a nippy bonus, give it a spin. It kept me busy, and I’ll be back for another go.
