Goi Coins

Goi Coins is a word game where you toss oval koban coins, each engraved with a different hiragana, onto a 3D table with real physics. You combine the letters that land face-up to make words, aiming for as many, as long and as valuable as possible. A dictionary of over 80,000 words judges each play.

Choose and reroll

You can shape your hand in three ways:

• Acquire: gain a new coin into your hand each round.
• Transform: use ink to rewrite an unwanted letter as another one.
• Keep & Reroll: lock in useful faces and roll only the remaining coins.

Choosing when to settle matters as much as luck.

Game modes

• Solo (High Score): beat your personal best and climb the global ranking.
• Local 2-Player: take turns on one device.
• Online Versus: play turn by turn in a random match or a passphrase match, and watch your opponent’s turn.

Words and setting

Each word you make displays its meaning, and words you learn are added to a word codex. The game also includes achievements. Its setting is a dim tatami room lit by a paper lantern, with ink-lettered coins and calm music.

The interface and dictionary are in Japanese only.
