STAR CIPHERSTAR CIPHER

Type the answer. Stop the enemy.

STAR CIPHER is a single-player typing action game for practicing English vocabulary. Read the meaning above each enemy, type the matching English word or expression, and fire before it reaches your defenses. Build combos, beat your best score, and use a time-stop skill when the screen gets crowded.

100 chapters of words and short expressions

The full game includes 100 chapters with 3,000 vocabulary entries. Clear a chapter's first wave to unlock the next chapter, then push through faster waves for more stars and a higher score.

Read, listen, and practice

Explore chapter comics and dialogue notes with English sentences, translations, and word and sentence audio. Practice without losing your shield or chasing a combo. Adjust the speed, use hints, and switch between word and sentence exercises.

Choose your companion

Kai, Nova, and Bolt are available from the start. Earn bronze, silver, and gold character cards through vocabulary collection, challenge combos, and practice time. These are in-game collectibles, not Steam Trading Cards.

Bring your own vocabulary

Create custom chapters in the full game using your own meanings and English answers, then play them in practice or challenge mode. Custom pronunciation uses English voices installed on your device.
