Coin UP: Lightning by ThreeOaks

Provider: 3 Oaks Gaming | Type: Hold & Win Slot | RTP: 95.67% | Max Win: 500× stake

Coin UP: Lightning is 3 Oaks Gaming's compact, high-energy take on the Hold & Win format. The action plays out on a 3×3 grid with three fixed paylines — but paylines are largely beside the point here. The real game lives inside three distinct bonus rounds, each with a different risk profile, all accessible through a Bonus Buy feature for players who want to skip straight to the action. Sticky coins, respin mechanics, and a Grand Jackpot ceiling of 500× are the building blocks. It is a tight, focused slot built around one question: how many coins can you collect before the board fills up?

Game Overview

How to Play

1. Set your bet and press Spin

2. Match three symbols on an active payline to trigger a bonus game

3. During Hold & Win, landed coin symbols become sticky — three respins reset with each new coin collected

4. Collect as many coins as possible to build toward the Grand Jackpot (500× stake)

5. Use Bonus Buy to access any of the three bonus games directly, without waiting for a natural trigger

6. Autoplay runs a set number of spins automatically

Key Features

Three Bonus Games Each of the three bonus rounds carries a different risk-reward balance. Players who buy in directly can choose the game that suits their current risk appetite — a genuine decision point that sets this slot apart from single-feature competitors.

Sticky Coins & Respins When coin symbols land during the bonus, they lock in place. Three respins are reset every time a new coin appears. The goal is to fill as many positions as possible before the respins run out, with each filled position adding its value to the total.

Boosters Special booster symbols modify the active bonus in real time — increasing multipliers, adding extra coins, or resetting respins. These can meaningfully change the trajectory of a bonus round.

Grand Jackpot The top prize in the Hold & Win bonus. Filling the entire 3×3 grid with bonus symbols awards the Grand Jackpot, which is capped at 500× the stake.

Bonus Buy Direct access to any of the three bonus games at a fixed cost. Useful for players who prefer to control when and how they enter the main feature rather than waiting for organic triggers.

Frequently Asked Questions

Q: What is the RTP of Coin UP: Lightning? A: 95.67% — slightly below the industry average, which is typical for Hold & Win games where the core value is concentrated inside bonus rounds rather than base game spins.

Q: How do the three bonus games differ? A: Each bonus game has a different number of starting positions, respin count, and multiplier structure. The higher the risk profile of the chosen bonus, the greater the potential payout — and the harder it is to collect enough coins to reach the Grand Jackpot.

Q: What triggers the Hold & Win bonus organically? A: Three matching symbols landing on an active payline during base play. This can take many spins, which is why the Bonus Buy option exists.

Q: What is the maximum win? A: 500× your stake, achieved by filling the grid during the Hold & Win bonus.

Q: Is demo mode available? A: Yes — Coin UP: Lightning can be played in demo mode at FatBet without registration.
