Used Corvyn for Android?
Editors’ Review
Corvyn, by Hai Beauty, is a compact Android logic puzzle designed to test observation and reasoning with Latin square challenges. Players fill a vertically oriented 'tidal chessboard' of diamond-shaped cells using a numeric key system, ensuring each row and column contains unique values in a Sudoku-like Latin square framework. Difficulty progresses from order 4 to order 6, scoring rewards completed rows, and rounds end after three incorrect placements. Suitable for casual mobile gamers and fans of logic puzzles seeking quick, mentally engaging sessions.
What kind of logic puzzle does the app present?
The app adapts Latin-square constraints into short, turn-based deduction sessions on a vertically oriented diamond grid. Players scan partially filled cells, infer absent numbers, and place digits so no row or column repeats a value. The design privileges observation and reasoning over reflexes, making each decision depend on cross-checking multiple lines rather than fast taps or pattern memorization.
Does the app introduce distinct mechanics or modes?
Rather than multiple modes, the challenge arises from a compact rule set and escalating board size. Core mechanics include:
- numeric key input for direct entry
- scoring tied to completed rows
- a three-strike limit that ends a round
What does the interface look like on a phone?
The interface uses diamond-shaped cells arranged in a vertical "tidal chessboard," a visual choice that keeps the playfield tall and narrow for single-handed use on mobile. The APK is compact, roughly 7.55 MB, and the app is distributed both as an APK and through the Google Play storefront for Android devices. Controls center on quick numeric taps rather than drag gestures.
Is it approachable for newcomers and worth repeating?
Sessions are brief by design, encouraging repeated plays to sharpen deduction rather than long runs. The stepwise increase in board complexity encourages a learning curve that rewards pattern recognition, while the three-error rule raises tension in later rounds. Replay value comes from solving varied Latin-square instances under a time-conscious rhythm, so short sittings fit both commutes and spare minutes.
Pros
- Latin square logic adapts Sudoku reasoning to mobile-friendly grids
- Vertical diamond grid optimized for single-handed play
- Numeric key input speeds number entry
- Small APK footprint (~7.55 MB) keeps download size low
Cons
- Rounds end after three incorrect placements
- Top complexity capped at order six boards

Bottom Line
An inviting, focused puzzle for short mobile sessions
The app is a compact, thoughtful choice for casual mobile gamers and fans of logic puzzles who prefer short, reasoning-heavy play. Its design rewards methodical thinking and quick decision cycles, making it suitable for commute-sized sittings. Players seeking cooperative or social features should note its concentrated solo puzzle focus; this is a title built around individual deduction rather than community play.
