About Caseoku
Read the clues. Find the killer. Caseoku is a daily murder mystery logic puzzle: a sudoku-style grid turned into a crime scene, where every case is solved by pure deduction. Every day, three new cases open: Easy, Medium and Hard. Every detective in the world gets the same mysteries, the same suspects and the same clues. Can you crack all three? HOW TO PLAY Study the crime scene: a grid split into rooms, full of beds, plants, tables, chairs and more. Read the clues: "Anna was the only person in bed", "Blanca was next to a plant and a bed". Rule out squares: cross out every position that breaks a clue. Place every suspect: one person per row and column, just like in sudoku. Unmask the killer: the victim was alone with the murderer. Find out who shared the room. CRIME SCENES TO INVESTIGATE House, Street, Beach, Forest and Office, each with its own objects, room shapes and types of clues. New scenarios keep arriving with updates. FEATURES 3 new cases every day: Easy (6x6), Medium (7x7) and Hard (8x8). One solution per case: every puzzle can be solved with logic, no guessing needed. Hints when you're stuck, without spoiling the case. Detective notebook: rule out squares, mark candidates and undo any move. Interactive tutorial: learn the rules in a couple of minutes. Available in English, Spanish, French, German, Italian, Dutch and Portuguese. Cloud sync: sign in and keep playing on any device. FOR FANS OF Sudoku, logic grid puzzles, Einstein's riddle, whodunit mysteries, detective games and brain teasers that reward careful thinking. Download Caseoku and solve today's murder mystery!
