Tips for solvers
- Read every clue once before marking anything, then start with the “is” clues: each one gives you a ✓ straight away.
- After every ✓, cross out the rest of that row and column inside the same block.
- When a row has only one empty cell left, that cell is the ✓.

Questions people ask
What is a logic grid puzzle?
A deduction puzzle where each person is matched with one item from every category. Clues rule pairings in or out, and the grid lets you record each deduction with ✗ or ✓ until only one arrangement is left.
Is this the same as a zebra or Einstein puzzle?
Yes, it is the same family. The famous "zebra puzzle" (often credited to Einstein, without evidence) uses 5 houses and 5 categories; these sheets use smaller grids that fit one printed page.
Do the puzzles have only one answer?
Yes. The generator checks every possible arrangement against the clues and keeps adding clues until exactly one arrangement is left, then removes any clue that is not needed.
How do I print without the answers?
Untick "Print answers" before printing. Answers are on a separate page, so you can also just print page 1.
Can I make my own instead?
Yes. The logic puzzle maker makes new puzzles with your own settings in a second.
