About This Game

Roll the coins, make the words

Toss oval "koban" coins — each face engraved with a different hiragana — onto a 3D table with real physics. Combine the letters that land face-up to form as many, as long, and as valuable words as you can. A dictionary of over 80,000 words judges every play.

Choose and build

• Acquire — gain a new coin into your hand each round.
  
• Transform — rewrite an unwanted letter into another in ink.
  
• Keep & Reroll — lock the good faces and roll only the rest.

It is not just luck — knowing when to settle is what wins the round.

Compete and battle

• Solo (High Score) — beat your best and climb the global ranking.
  
• Local 2-Player — take turns on one device.
  
• Online Versus — random match or passphrase match, turn-by-turn, where you can watch your opponent's turn.

Grow your vocabulary

Each word you make shows its meaning, and the words you learn are collected in a word codex. The more you play, the more Japanese you discover — vocabulary grows as you play. Plenty of achievements, too.

A quiet Japanese world

A dim tatami room lit by a paper lantern, ink-lettered coins, and calm music. An understated Japanese atmosphere that lets you focus on the words.

Who is it for?

• Fans of word games and word puzzles
  
• Anyone wanting a game for both short sessions and longer play
  
• Those who like a calm, Japanese aesthetic
  
• Players who want to face friends online or locally

Note: The game's interface and dictionary are in Japanese only.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some of the 3D models used for the table and room background in this game were created with the assistance of a generative AI (text-to-3D) tool, and were then adjusted and integrated by the developer. All other assets — including the dictionary data, UI artwork, sound, and all in-game text — were produced without generative AI. No content is generated by AI while you play.
