Koi Drift: Zen Koi Puzzle

Koi Drift is a calm logic puzzle painted in watercolor on washi paper. Read the pond, find the right order and release every koi into the river.

Each koi swims only the way it faces. Tap a koi whose path is clear and it glides out of the pond, leaving rings on the water. Tap one whose path is blocked and it bumps softly and swims back — no penalty, just a wave. Find the order, release them all and watch the last koi rush out in a shimmering chain.

Every pond you clear helps the river remember: stone lanterns glow again, bridges return, a heron comes back to the shallows. The koi you release join the river on the home screen.

WHAT'S IN THE POND
• 400 ponds across 8 river seasons, each one checked solvable by a solver
• A new river rule every season: lotus gates that open and close with every koi, frogs on lily pads, leaf eddies that turn a koi's path, frozen koi that thaw, turtles that turn instead of bumping, reed currents — and all of them together under the moon
• The Nushi: an ancient giant koi waits at the end of each season. Free it and watch it rise as an ink dragon
• 24 koi varieties to befriend in a hanging-scroll album — Kohaku, Showa, Asagi, Ogon and more
• Morning Pond: a new pond every day. Missed a morning? Catch up within 3 days and keep your streak
• Lantern Festival: the first week of every month, a night pond lit only by floating lanterns
• Long-press any koi to see its path. Undo and restart are always free and unlimited

MADE FOR CALM
• No timers, no lives, no fail screens
• No interstitial or banner ads. The only video is an optional one you choose to watch for a hint
• Plays offline; your progress stays on your device

FREE AND FAIR
Free: 4 full seasons (200 ponds), the daily Morning Pond, the monthly Lantern Festival and 2 free brush strokes (hints) every day.
Optional one-time purchases: The Sage's Brush gives unlimited hints forever, shows two moves ahead and hides the optional videos. Each season pack adds 50 ponds, a new rule, a new river and 2 koi — the first pond of every pack can be tried for free. Complete Garden brings the Brush and all four season packs together.

A relaxing brain teaser for anyone who loves koi ponds, Japanese gardens and quiet logic puzzles.
