Logic Grid Puzzles
Logic grid puzzles give you a set of categories — names, pets, drinks — a handful of clues, and one question: who goes where? You solve them by elimination: every clue lets you rule pairings in or out until only one arrangement survives. Play below, free — this is the same classic known as the zebra puzzle or Einstein’s riddle, and every board here has exactly one logical solution. Prefer pencil and paper?

How to solve a logic grid puzzle
- Read every clue once before touching the grid — some clues only make sense in combination.
- Bank the direct facts first — clues like “Cleo is the milk drinker” or “the cat owner is in seat 1” fill cells immediately.
- Turn relative clues into eliminations — “A is left of B” means A is not in the last seat and B is not in the first.
- Cross-eliminate — every placement you confirm removes that value from the rest of its row and column.
- Revisit the clue list after each placement — a clue that told you nothing earlier often becomes decisive once one value is fixed.
- Finish when every category is placed — one arrangement will satisfy every clue; that is the solution.
What counts as a logic grid puzzle?
Any puzzle where you match values across categories from verbal clues, using a grid to track eliminations, is a logic grid puzzle. The format goes by many names — zebra puzzle, Einstein’s riddle, logic problem, grid-deduction — but the mechanics never change: categories, clues, elimination, one answer. The famous original asks who owns the zebra; ours generate fresh scenarios endlessly, at 3×3 (three categories, three positions) and 4×4.
The grid itself is the technique: it turns a paragraph of prose into checkable cells, so you never hold the whole state in your head. That is why the format is a staple of critical-thinking classrooms — and why it stays satisfying: the answer is always provable, never guessed.
