The Iron Butte Business: a free Western logic-grid puzzle

There was a dust-up near Iron Butte before the week was out, and by sundown every story on the circuit contradicted the one before it. There's an answer in here. Find it.

This free Rookie logic-grid puzzle has 4 suspects, 4 locations, and 4 pieces of evidence. New to logic grids? Start with the pencil-solving guide.

How to mark the grid

●
These two belong together.
✕
These two are ruled out.
blank
Still undecided.
How to play

Click, tap or press Enter on a cell to cycle it: blank, then ● for a confirmed pairing, then ✕ for one you have ruled out. Nothing fills itself in — the deductions are yours to make. Use the arrow keys to move around the grid.

Fill obvious Xs does the bookkeeping only: for each ● you have marked, it crosses off the rest of that pairing's own row and column. It never adds a ●, never reads a clue, and never changes a mark you made.

On a narrow screen the grid scrolls sideways.

Every case has exactly one solution, and it is always reachable by deduction alone. Nothing here guesses for you, and Check will not tell you which mark is wrong.

Clues and evidence

  1. Redeye Hank's presence at Dry Gulch was no secret.
  2. Everyone agreed: Tin-Star Tucker had the half-melted candle.
  3. The deputy struck the busted pocket watch off Ragged Ruth's account.
  4. Tin-Star Tucker was nowhere near Iron Butte.
  5. Ragged Ruth swore never to have set foot in Coyote Bend, and the ledger agrees.
  6. Ragged Ruth never laid hands on the scorched playing card.
  7. Tin-Star Tucker never made it as far as Coyote Bend.
  8. You can rule out the busted pocket watch for Ironjaw Hobbs.
