Stamp papers with a dog's tail

Stamp it with your tail.

Ohagi, a chihuahua and section chief at the Wan-Wan City Office, takes his hanko — the name seal stamped on every Japanese document — very seriously. Swing the seal hanging from the tip of his tail, ink it, and press it inside the box: straight, centred and with just the right push. Every stamp is checked, strictly, by Chief Neko of the Review Section.

Chief Ohagi stamping a document with the seal on his tail

Features

  • 1

    A seal on a tail

    The tail fidgets by itself. Get the swinging seal into the box, straight and with the right push.

  • 2

    One office week

    Monday to Friday, each day adds a small, silly, very important rule, like the bowing stamp or a seal across two sheets.

  • 3

    Stamp Moves

    The way you press earns a name, from "Dead Vertical" to "Third Time Lucky", collected in a book.

  • 4

    Every stamp says 犬

    The seal prints 犬 ("dog"). Faint, smudged or chipped prints show in the way it looks.

  • 5

    Chief Neko is strict

    Outside the box, crooked or faint? Returned. Clear every document before 17:00 to finish the day.

How to play

  1. Aim the seal with the mouse and change its height with the wheel (keyboard and gamepad work too).
  2. Hold the left button and let go while the force bar is in the green band. Ink the seal the same way.
  3. Hold the right button and move sideways to turn the seal. When the tail gets fidgety, take a deep breath.
  4. Outside the box, crooked, faint or smudged? The document is returned. Clear them all before closing time.

FAQ

Can I play on my phone?

For now, it's playable in a PC browser on unityroom.

Any ads or purchases?

The browser version has neither.

Can I put a seal on my dog's tail?

Only Chief Ohagi in the game can hold a seal with his tail. Please never tie things to a real dog's tail or pull it — dogs don't like their tails being touched.

Is it in English?

The current browser version is in Japanese only.

Do you use AI?

The dogs' 3D models were made with Meshy, then picked and adjusted by the developer (the same models as Chiwa-Chiku RUN). The code and text were written with Claude Code and reviewed by the developer. No AI content is generated while you play. Music and sound effects are human-made.
