Coin Up Lightning revolves around a 3x3 reel grid where the goal is to collect special coin symbols instead of chasing traditional paylines. Landing six or more coins anywhere triggers the Hold & Win bonus, locking these symbols and awarding three respins. Each new coin resets the respin count to three, extending the bonus round's duration. During this round, booster coins like Coin Up and Multi Up appear to multiply coin values and total winnings, creating dynamic and potentially large payouts.
