Thunderline Express: Supercharged

Thunderline Express: Supercharged is a 3-reel slot built around a dual-layer coin collection system — Golden Coins feed a Hold & Win bonus while Jackpot Coins unlock their own separate Hold & Win with fixed jackpots up to 500x, and a Lightning Counter that charges with every Wild adds multipliers of up to x5 to coin prizes during both features. The paytable runs from low-value fruits at 1x up to a lightning bolt symbol at 50x, keeping the base game lean while the real action comes from stacking coin values and multipliers across respinning reels. With a max win of 4,530x, it's a medium-ceiling game that trades single-hit potential for layered bonus mechanics.
