Logic Grid Puzzles

About Logic Grid Puzzles

LogicGridPuzzles.com is a free site for classic logic grid puzzles, also called logic problems, elimination puzzles or zebra puzzles. Every day it publishes a dated, numbered pack of six puzzles at rising difficulty, shown as one to six light bulbs, so you can take a quick warm-up or settle into something that holds you for half an hour.

Each puzzle has a title and a short scenario, such as tourists comparing Colombian coffee regions or five men placing ceramics around the house. You read the numbered clues and click cells in the grid to mark a match or a no-match. Confirming a match automatically rules out the rest of that row and column, which helps you chain deductions. There are undo, redo and reset buttons, an Answer tab, and a Past Puzzles button for earlier packs. The site also links printable puzzle books.

No trivia is involved: every clue is needed and the solution is unique. It suits anyone who enjoys careful reading and step-by-step reasoning.

How to play Logic Grid Puzzles

1. Open logicgridpuzzles.com and pick a difficulty from the light-bulb tabs.
2. Read the scenario and the numbered clues.
3. Click grid cells to mark a match or a no-match; a match clears the rest of its row and column.
4. Keep combining clues until every item in each category is paired, then move on to the next difficulty.

Tips

• Start with clues that state a direct fact, such as a named person's age, then work on the either-or clues.
• Clues that compare positions (before, after, between) usually rule out the ends of a range first.
• Use undo rather than reset when one deduction turns out wrong.
