HOW TO PLAY

How to play Tower Cipher

Deduce a unique-digit code from seals (exact place) and echoes (digit only). The daily cipher is the same for everyone.

English guides and UI are ready. A few niche in-game lines may still appear in Japanese.

Basic flow

  1. 01

    Weekly Rune offers four digits and eight guesses, with public even/odd clues for each position (zero is even). It changes at Monday midnight JST.

  2. 02

    Your input and feedback save automatically, and the starting puzzle date stays fixed when you resume.

  3. 03

    Choose a mode: daily, practice, or Sage’s Trial.

  4. 04

    Enter a guess with unique digits.

  5. 05

    Seals mark exact matches; echoes mark digit-only matches.

  6. 06

    The notebook tracks candidate reductions and checks your entry against earned clues. Using it carries no score penalty.

  7. 07

    Open the seal before you run out of attempts.

Tips

  • Digits never repeat, so each guess cuts many candidates.

  • Start with wide spacing to map the board quickly.

  • The daily cipher is the same for everyone on that date.
