SQL Mysteries: Cold Query is a detective game where every clue is hiding in a database. You play as the newest intern in Meridian Falls PD’s basement archive, solving cold cases by writing real SQL queries. Question witness lists, filter evidence logs, sort timelines, join records, and follow the data until the paperwork gives up the truth. No dry lessons. No flashcards. Just suspicious librarians, missing files, crooked alibis, and one very tired detective dummy named Archie. Features: • Learn SQL by solving playable mystery cases • Practice SELECT, WHERE, ORDER BY, LIMIT, joins, grouping, aggregates, NULLs, and subqueries • Get instant feedback when your query catches the right clue • Build an evidence board as each case unfolds • Track XP, streaks, and skill progress in your detective dossier • Play the opening cases free, then unlock the full case library with the Season Pass If you’ve ever wanted to learn SQL without feeling like you’re trapped in a spreadsheet basement, welcome to the basement.

Cross the clues and find a cozy spot for every cat. MiauDoku brings together two kinds of logic puzzles: Cat Corner, where you arrange cats in a home around their individual needs, and a classic mode built around rows, columns, and colorful regions. CAT CORNER — 20 LEVELS Each cat has its own clues. Some need a sunny spot or a cushion; others want to sit beside a companion, have an exact number of neighbors, or stay in a different room. Find a place for every cat while following the room counts and working around the furniture. • Combine clues about cats, rooms, and counts • Work through home layouts with progressively challenging puzzles • Place and move cats freely while you test an idea • Tap Check arrangement when every cat has a place • A fully checked incorrect arrangement costs one life; moving cats does not • Enlarge clue cards for easier reading • Use hints, undo, restart, and resume your game CLASSIC MODE Place exactly one cat in every row, column, and colored region. Cats cannot touch, even diagonally. • 120 levels with varied board sizes • Relaxed and Time Attack modes • Daily challenge and play streak • Weekly leaderboard with locally simulated participants • Hints, reveals, and extra lives ENGLISH AND PORTUGUÊS (BRASIL) Choose English or Português (Brasil) in Settings. Changing languages keeps your saved progress on the device. YOUR PROGRESS STAYS ON YOUR DEVICE Play without an account, cloud sync, or real-money purchases. Your progress is saved locally. Puzzles work offline; ads depend on an internet connection and availability.

Verdict
The clearest difference is in-app purchases: MiauDoku at none against SQL Mysteries's 1. MiauDoku also leads on update cadence (every 10 days vs every 6 weeks). SQL Mysteries's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
