LogicGridPuzzles.com posts a numbered pack of six logic grid puzzles every day, free in the browser with no sign-up. Each one gives a short story, a list of clues and a grid where you mark matches and eliminations until every item is paired.

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 three jewelry designers scoring points for a bracelet, a necklace and a pendant. 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. On a phone the difficulty tabs turn into a drop-down above the grid and the clues sit below it. The site also links printable puzzle packs.

A single ad slot sits beside the grid on desktop and above it on a phone, with a paid option to remove ads.

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

Open logicgridpuzzles.com and pick a difficulty from the light-bulb tabs.
Read the scenario and the numbered clues.
Click grid cells to mark a match or a no-match; a match clears the rest of its row and column.
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.
