Who's ready for a party with unique windsocks? Koinobori Party is an online slot game created by Zitro inspired by popular Japanese carp streamers. Visually, it's a vividly-colored game with transparent bluish reels featuring shiny symbols. The background image depicts a lake in front of a traditional Japanese building and subtle animations.

Koinobori Party is equipped with 5 reels and offers 243 ways to win. The paytable includes thirteen basic symbols: four playing cards, an envelope, a bell, a mask, a fox mask, a shogun's mask, and golden versions of the last four icons. The koi windsock is a wild icon that replaces basic symbols. Players activate eight Free Spins when they get three or more scatters on the reels. During this round, the wilds multiply the wins, where they contribute by two.

Players can activate a special round with three free spins when they land a golden circle. This round enables them to win one of the five progressive jackpot prizes.
