Logic Grid: Deduction Puzzles

Read the clues, mark the grid, crack the case.

Logic Grid: Deduction Puzzles is a calm, clever puzzle game for people who love working things out. Every puzzle tells a short story: four neighbours share a garden, five runners finish a race, a prize pie goes missing from the fair. Each person goes with exactly one item from every list. Read the clues, cross off what can't be true, and the one answer appears.
