Free printable Red-Handed cases
500 print-ready PDF packs. Each pack holds six cases, and each case gives you the crime, the forensic findings, every suspect's account, and a seating worksheet with a blank for each chair and each piece of evidence. The answer key at the back names the culprit and quotes the account that could not have been true.
Easy Red-Handed
Four suspects, three rooms and two objects. Short chains, and enough room on the page to write every step out.
Medium Red-Handed
Five suspects and a third object. Working out where an object was usually settles somebody you could not place directly.
Hard Red-Handed
Six suspects across four rooms. Fewer people share a room, so more of the board has to be inferred rather than read.
Expert Red-Handed
The same board as Hard with a fourth object and a longer chain. Every case here takes five rounds of reasoning.
Sherlock Red-Handed
Two false accounts instead of one. One liar was alone at the scene and did it; the other lied for reasons of their own.
About these worksheets
Each PDF is four pages: three case pages with two cases each, then an answer key. On screen you drag people into chairs, so on paper every case carries a worksheet instead. There is one row per room with the chair count printed, a ruled blank for each person, and a slot for the object found there. The scene is marked, because whoever ends up alone in that room is the one who lied.
Packs are numbered in order within each difficulty. Pack 01 holds cases 1 to 6, Pack 02 holds cases 7 to 12, and so on. Every difficulty has 600 distinct cases, and each one was checked by a separate program that proves the answer is reachable by reasoning rather than merely unique.
If you would rather solve interactively, play online with undo and a reveal. The rules guide walks through the seven techniques, including the one most solvers miss: narrowing the lie to two people also clears everybody else.
