Niwa: Japanese Logic Puzzles

One beautiful puzzle a day in three quiet worlds. No ads, no trackers, no payments, no clutter. Just the board and a clear mind. New puzzles forever, made to be lived in.

Niwa is a free, calm, beautiful puzzle garden. One puzzle a day in three quiet worlds, each a classic Japanese logic puzzle, refreshed forever by the app itself.

Open, tap, play. No account, no sign-up wall, no ads, no payments. Just the board and a clear mind.

THREE WORLDS, THREE WAYS OF THINKING

Kame, the tortoise, in the afternoon on stone. Divide the garden into rectangles, one number in each. A puzzle about seeing structure.

Kujaku, the peacock, at night. Split the garden into balanced regions, each one turning around its own dot. A puzzle about reading symmetry

Koi, the carp, at dawn on the water. Trace a single quiet loop past the pearls. A puzzle about following a path.

MADE WITH CARE

A fresh puzzle in every world, every day, generated on your own device and always solvable by pure logic. No guessing, ever.

Learn by doing. There is no wall of rules. Each world teaches itself in a few gentle taps.

Hints that teach the next step instead of spoiling the answer.

Fully playable offline. Your progress lives on your phone.

An optional global leaderboard, if you enjoy a quiet sense of standing. Play with a name, or play with none.

QUIET BY DESIGN

No ads. No trackers. No analytics. Niwa asks for a few calm minutes a day, and gives them back to you.

Tend your mind.
