A pencil-and-paper puzzle, with a frontier case around it
Western mystery logic-grid puzzles that play fair.
Each Frontier Logic case starts with a small trouble in Arizona Territory, then gives you the suspects, places, evidence, and clues needed to settle it. There is no hidden twist to guess: one arrangement survives the evidence.
What makes a western logic-grid mystery?
The setting gives the puzzle something to investigate: a disputed ledger, a missing parcel, a trail that does not match a rider’s story. But the job is still deduction. You compare every suspect with every location, piece of evidence, and motive until the grid can hold only one complete set of pairings.
The western detail is never a substitute for logic. Every clue is a usable fact. If a clue rules out a pairing, mark an X. If it establishes one, mark a circle and let that result rule out the rest of its row and column.
Fair means one answer.
Every printed case is built to a single solution and checked so that a second arrangement does not survive. You can solve by deduction alone, without intuition, outside knowledge, or a reveal that changes the rules.
Start where the book starts
- Read the case and labels. Notice what each person, location, and item is called before marking the grid.
- Take the direct eliminations. A firm “not” belongs in the grid immediately.
- Use the forced follow-through. A confirmed pairing closes its row and column to every other option.
- Check only after you have a full arrangement. The answer key is there to verify your reasoning, not replace it.
