CIPHERCASE

Each case opens with a 10×10 grid and sixteen words — but only fifteen can be found. The missing one is your suspect. The leftover letters give you the crime scene and a four-letter code. Convert, subtract, decode: the weapon or method is the last thing you learn.

Three puzzles inside every case. A word search hides the crime scene, a number conversion tells you which cipher to use, and a card puzzle spells out the weapon. No case is solved in one step.
