I had a crazy idea a couple months ago and decided to make a sudoku inspired by ‘murder boards’ always show up in TV shows and movies. I have no idea if this is a real thing that real detectives use, but as a ‘sudoku detective’ you’ll need to navigate all these unknown ‘killers’ to solve the mystery.
Happy hunting!
Really tricky one! Cracked it by using split screen on iPad, with a duplicate of the grid for hand-written notes of the possible cage values. Good fun!
