## Description

Match tiles and you don&#39;t score points. You earn clues. Every match asks the board a question, and every answer is true. Use as few matches as possible to gather enough information to locate every hidden glyph, then confirm those cells by pure deduction.<br><br>If you enjoy grid logic puzzles (the nonogram and sudoku family), this plays in familiar territory with an unfamiliar move: you dig for information with match-style swaps.<br><br>How it works:<br>- Swap neighboring tiles to line up three or more matching glyphs. The line writes down a true clue.<br>- Combine clues to work out where each hidden glyph must be, and where it can&#39;t be.<br>- Confirm a cell only when the evidence is sufficient. One confirmation cascades into the next.<br><br>The contract this game keeps:<br>- Every puzzle has exactly one solution.<br>- No guessing is ever required: pure deduction always reaches the answer.<br>- Every clue a match gives you is true.<br>- The clues available within the ink budget are always enough to decide the board.<br><br>Chapter 1 and daily puzzles:<br>- Chapter 1 opens one page at a time, like a codex. The first four pages teach the rules step by step.<br>- Daily puzzles are arranged by date, and past boards stay open to solve anytime.<br>- Records stay quiet: a calendar and your longest run. No streak nagging.<br><br>No account is required. Core play works offline, and progress is stored locally on your device.<br><br>Made to be comfortable:<br>- Hints point out one confirmation that is actually derivable right now.<br>- All puzzle information remains visible, so you can play with your device muted.<br>- On foldables and tablets, the board opens like a two-page spread.<br><br>Support: English and Korean.
