語彙コイン

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?
