Coin UP : Lightning

Coin UP: Lightning by Booongo is a 3x3 slot with a lightning theme and active-line gameplay. The reels are accompanied by crackling bolt effects, while three matching symbols on an active line trigger the bonus game. A demo version is available for players who want to play for free and practice before playing for real money.

During the bonus round, the game starts with three respins, and each new winning symbol resets the counter. Special symbols include MINI, MINOR, MAJOR and GRAND bonus values, along with MYSTERY SYMBOL, MYSTERY JACKPOT SYMBOL and a Collect symbol that adopts the value of other symbols it meets. If the grid is filled with symbols during the bonus, the GRAND JACKPOT prize is awarded.

An extra row above the reels can unlock boosters such as COIN UP, SUPER COIN UP, MULTI UP and SUPER MULTI UP, which increase or multiply symbol values. The slot also includes ULTRA BONUS GAME and THUNDER BONUS GAME features, while sticky symbols in the main game may remain in place until a bonus is triggered.
