Bonus Features & Mechanics

Rainbow Fish in a winning line starts a respin at the stake; all fish share one colour and it cannot retrigger. Autoplay runs selected spins or stops at a feature. Turbo changes reel speed and win effects; UFO Pyramids also includes Autoplay.

Reels and win evaluation

Koi Harmony uses three reels, one row and one permanently active payline. Line wins are evaluated on adjacent reels from left to right, beginning with the leftmost reel. The total bet is 10 times the selected coin value, with currency values calculated from coins multiplied by that value.

Rainbow Fish respins

A winning combination with one or more Rainbow Fish segments awards one respin at the triggering spin's bet. During that respin, all fish parts use one color—Purple, Green, Red, Gold or Rainbow—and any resulting line win is paid according to the paytable. It cannot retrigger during the respin.

Autoplay and Turbo controls

Autoplay spins reels automatically for a selected number of spins or until a feature triggers, and STOP can end it. Turbo changes reel speed between faster and normal settings while enabling or disabling some win animations and sounds.

Koi Harmony Paytable

The koi symbol represents the game’s central aquatic theme and serves as a key visual symbol during play.

FAQ

The listed RTP is 96.47%. RTP is a long-run theoretical return figure, not a promise that an individual session or spin will return that percentage. Actual results can vary from spin to spin, and the supplied rules do not state a separate session result or payout guarantee.

No volatility classification is given in the verified game data. The available record identifies the reels, payline, ways to win, RTP and named features, but it does not label Koi Harmony as low, medium or high volatility. Session variance therefore cannot be classified from these rules alone.

The visible paytable lists six koi value tiers, ranging from x8 to x888, with x888 the highest displayed multiplier. The verified material describes these as displayed symbol multipliers; it does not provide a complete probability table or state how often any particular tier appears.
