Zebrapuzzles.com – Daily Logic Puzzles
Hi all, I've always been fascinated by logic puzzles and, over the past 15 years, I've published around 300 zebra puzzles, mostly in Portuguese. Now, using LLMs, I've managed to automate the creation of these puzzles, leading to the birth of ZebraPuzzles.com. There are around 80 different themes that the generator uses to transform a raw puzzle into a thematic one. For instance, the LLM translates this clue: >The girl Shirt=Pink is next to the girl Age=11 to >The girl who wears a Pink shirt is next to the 11-year-old girl.

Play free zebra puzzles daily. Classic logic puzzles to challenge your mind. New puzzles every day!
Six fresh zebra puzzles land on this page every morning, and all of them are free. No account, no download, no counting how many you have left. Pick a difficulty, read the clues, and start placing items in the table. The board checks each move against the clues as you go, so you always know whether the arrangement in front of you still holds up. A zebra puzzle hands you a row of positions and a handful of categories, then makes you pin down every pairing from the clues alone. Nothing here depends on what you happen to know, only on how carefully you read and how far ahead you can follow a deduction. That is why the format has outlived the riddle that made it famous, and why it works so well…from zebrapuzzles.com
