Layers of pigment, one over another. Deduce the order they were painted and the koi climbs the river. One rule, a hundred pools, five seasons. No timers. No forced ads.
Layers of pigment, one over another. You see only the finished canvas — deduce the order they were painted, and the koi climbs the river.
Kasane (重ね, "layering") is a new kind of logic puzzle. The rule takes ten seconds to learn: every canvas was painted one rectangle at a time, each layer covering what came before. Read the layers back, from the first laid down to the last. That's it — and it's enough for a hundred pools and beyond.
ONE RULE, REAL DEDUCTION
Every puzzle is generated and verified to have exactly one solution. No guessing, no trial and error — if you're stuck, the answer is always there in the picture, waiting to be read.
FIVE SEASONS ON ONE RIVER
A hundred pools climb from spring through summer, autumn, winter and night. Cross between seasons and the landscape draws itself in ink before your eyes — mountains, villages, koi ponds, river gorges — no two crossings the same.
MADE TO BE CALM
Warm paper, flat pigment, gentle water sounds and a koto phrase when the season turns. A timer runs, but only to reward the swift — nothing hurries you. No forced ads, ever.
INK, EARNED OR BOUGHT
Ink (墨) reveals layer edges and gives hints. Solve a pool perfectly and the river gives a drop back. Every pool is solvable with no ink at all — it is a convenience, never a toll.
OPEN WATER
Finish all five seasons and the river reaches the sea: endless freshly generated pools at five depths, from Shallows to Abyss. No two are ever the same.
The palette is colourblind-safe throughout. Progress lives on your device. Kasane collects no data — no accounts, no tracking, no analytics.
Read the layers back. The koi is waiting.
