Puzzle clues
Matching grid
A new puzzle appears only after a local exhaustive check proves it has exactly one solution. Generation is bounded and uses no external service.
How to play
Each value matches exactly one value in every other category. Use the clues to solve the relationships. In each grid, mark the four matches; the other cells can be inferred. Tap a cell to cycle through match, not a match and unmarked.
How do you solve a logic grid puzzle?
Use each clue to connect or rule out two values. Each value belongs to exactly one row in every category. Mark four matches in each relationship grid, then check your board. Ask for a one-cell hint when you need help.
