🧠 Logic grid puzzles
A new puzzle every day · 4 levels · free
Logic grid puzzles are “who’s who?” puzzles: a few kids, families or friends, and each one has a different item in every category. Solve them online on a real grid: mark ✓ and ✗, tick off the clues you used, and ask for a hint that explains the next step in words.
Pick a level
Start with the logic puzzles for kids with just 3 kids, move on to easy logic puzzles, and from there to hard logic puzzles with 4 categories. For teachers and car trips there are printable logic puzzles, and if you get stuck, see how to solve them with a full example.
How do you play? Read the story and the clues. Each small grid crosses two categories, for example kids and pets. When a clue says something is not true, mark ✗. When you find a match, mark ✓, and the rest of the row and column fill with ✗, because each kid has only one pet. The grids complete each other: if Emma has the dog, and the kid with the dog is 8, then Emma is 8.
There are four levels: kids (3 kids, 3 categories), easy (4 items), medium (4 categories of 4) and hard (4 categories of 5). The themes change: pets, houses and colors, sports, birthdays and gifts, lunch and the class field trip, with all kinds of clues: “yes”, “no”, “either… or…”, “before / after” and “next to”.
Logic puzzles build orderly thinking, patience and careful reading: every word in a clue matters. They are great as a quiet activity at home, a thinking lesson in class, gifted-test practice and for grown-ups who love puzzles.
Questions and answers
What is a logic grid puzzle?
A logic grid puzzle (also called an Einstein puzzle or zebra puzzle) has a few characters, and each one has exactly one item from every category: a pet, an age, a color and so on. Using the clues, you fill a grid with ✓ and ✗ until you know who has what.
Does every puzzle have exactly one solution?
Yes. The computer checks every puzzle before it is shown: it has exactly one solution and no unneeded clue. Remove any clue and the answer is no longer certain. Every puzzle can be solved with logic alone, without guessing.
What does the Hint button do?
It does not just give away an answer: it explains the next logical step in words and highlights the cell in the grid. If you have a wrong mark, the hint points to it first.
What is the daily puzzle?
Every day there is a new medium-level logic puzzle here, the same puzzle for everyone that day, so you can solve it with friends or in class and compare.
What age is it for?
The kids puzzle (3×3) suits about 2nd grade and up, easy suits grades 3–4, medium grade 5 and up, and hard (4×5) challenges adults too.
