Koimere

A koi pond puzzle game. Turn the stream, feed the koi who ask, and dig the old mill pond out of the sand, one stretch at a time.

This is the game running live. Tap the water, or tap a koi to meet it.

How it plays

Turn the stream
Rotate channel tiles until the spring water reaches every one. Food on a tile only counts if the water gets to it.
Feed the koi who ask
Koi swim up with orders. Fill them with the food you gathered and earn coins and experience.
Dig out the pond
Spend coins to dredge the next stretch of the old mill pond. It brings new koi, new food and room to decorate.

Koi ask for food. Turn the channels until the spring's water reaches every tile. Food only counts if the water gets to it.

The mill pond silted up years ago. In the game it's one long, winding pond you drag along, and each stretch under the sand opens as you level up.

Press dredge and watch the water come back.

Six real varieties to start. Each fish follows its variety's rules, and its pattern is grown fresh, so no two ever match.

Kohaku
White skin with red markings. The classic koi, and where most keepers start.
Tanchō
One round red spot on the head, named after the red-crowned crane.
Taishō Sanke
A kohaku pattern with small black accents on the back.
Shōwa
Black base with red and white, and the black reaches the head.
Ōgon
One metallic colour, gold from nose to tail.
Chagoi
Tea-brown and known for being friendly. Usually first to the food.

No lives, no energy bars, no timers and no loot boxes. Skip a week and the pond is just as you left it.
