When three symbols land on an active line, the bonus game begins with three respins, and each new win resets the counter. The slot includes BONUS SYMBOLS with MINI, MINOR, MAJOR and GRAND values, along with MYSTERY SYMBOL, MYSTERY JACKPOT SYMBOL and COLLECT SYMBOL features. Filling the grid can award the GRAND JACKPOT prize, while the extra row above the reels activates boosters such as COIN UP, SUPER COIN UP, MULTI UP and SUPER MULTI UP symbols.

Additional features include the ULTRA BONUS GAME, THUNDER BONUS GAME, STICKY COIN and sticky jackpot symbols, which remain in place until the bonus is triggered. The format is designed around short spins and frequent feature-driven outcomes.
