About Caseoku: Murder Sudoku Mystery
Caseoku is a daily murder mystery sudoku — the definitive logic challenge for aspiring detectives and puzzle lovers. Forget about guessing: in this crime scene, only pure deduction will lead you to the truth.
Every day, a new case is opened. Every player around the world receives the exact same mystery, the same suspects, and the same clues. Will you be the fastest to find the culprit?
HOW TO PLAY
Step into the shoes of a lead investigator. You're presented with a grid representing a crime scene and a series of clues in your detective notebook.
Analyze the Clues: "The victim is not in the Kitchen," "Alice is next to a plant"
Deduce and Rule Out: Use the clues to cross-reference positions and rooms, just like in a classic sudoku grid.
Identify the Killer: There is only one possible solution. Use your logic to fix the suspects in their correct places and solve the crime.
