Deduction

Five suspects. Multi-step reasoning chains. Evidence that serves double duty — one clue might clear suspect A while simultaneously implicating suspect B through a non-obvious connection. Expert cases reward careful, methodical work and punish snap judgments.

The scenarios get more complex too. Instead of simple "who stole the thing" setups, you get situations with diversions, tampered evidence, and suspects who had both motive and opportunity but still didn't do it. The guilty party often isn't the most obvious suspect.

A good approach: map out what each suspect would need for their guilt to be possible, then check which theory holds up against all the evidence. Only one works. The rest hit a contradiction somewhere.

For the ultimate test, try Einstein — same complexity, fewer clues.
