A new crime scene: the Hotel! Locked doors, one suspicious guest and 3 new cases every day. Can you solve today's murder?
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.
