A koi breeding game.

You manage koi in ponds, choosing fish to breed and raising new koi with different colors and patterns. The focus is on experimenting with combinations rather than following a story campaign.
Selective breeding lets you refine traits and uncover mutations, with genetic outcomes that can take several generations. You can move fish between the river and ponds as you sort through new offspring.
A koi book guides you toward undiscovered mutations and stores collected fish as cards. You can also generate koi codes to share fish and spawn them in another player's game.
Players often enjoy the calm, open-ended pace, using koi breeding to experiment with color and pattern combinations or work toward filling the collection book. Several describe it as a pleasant game to leave running in the background, and some praise its visuals and sound. Others find the breeding slow or the overall experience short, and storage limits and awkward fish handling come up as frustrations.
