Logic Parlor: Grid Puzzles

Logic Parlor brings you classic logic grid puzzles: the deduction puzzles from puzzle books and magazines, also known as zebra puzzles or logic riddles. Read the clues, mark the grid with ✓ and ✗, and work out who owns which pet, who lives in which town and who is the oldest, until only one answer fits.

500 logic puzzles from Easy to Expert, a new daily puzzle, big clear clues and hints that explain themselves. All free, all open from day one, and all playable offline.

Fair logic puzzles, no guessing
Every puzzle has exactly one solution, and you can always reach it by deduction alone. Our solver checks each one before it goes in the app, so you never have to guess or start over.

Big, readable clues
Clues are set in large, clear text that is never cut off. Choose from four text sizes, on top of your phone's own text size. Tap a clue to cross it out; press and hold to light up the squares it talks about.

No gates, no waiting
All 500 puzzles are open from the start, in 20 packs from Easy to Expert. No keys to earn, no minigames, no energy bars. Just logic puzzles.

A new logic puzzle every day
The daily puzzle keeps your streak going. Missed a day? Every past daily stays playable, so you can catch up any time. Turn on a gentle daily reminder if you like.

Hints that teach
Stuck on a tricky riddle? A hint reads your board and shows the next deduction and the clue behind it, so you learn the technique instead of just being given the answer. If there's a mistake on your board, the hint tells you that first. You get three free hints a day, and you can watch a short video for more.

• No timer unless you turn it on
• No lives and no penalties

Made to fit you

How to play
Each puzzle has a few categories, such as names, pets, towns and ages, and a list of clues. Use the clues to mark which items go together (✓) and which don't (✗). When everything is matched, the puzzle is solved. It's a brain teaser that rewards careful thinking, not luck.
