- Sudoku players who enjoy themed settings and extra puzzle layers
- Worth noticing
- The web version is explicitly limited to one fixed learning grid and four clue profiles, not an unlimited puzzle library.
Field notes
The sample keeps its scope explicit: one learning grid, four clue profiles, and listed controls for checking or erasing entries. The broader concept names five settings, from a cosmic nebula to a quiet garden, while presenting Cipher as an optional investigation track with five files of 36 boards each. The Google Play listing is still described as in preparation, so the mobile experience should be treated as planned rather than confirmed available.
