One logic puzzle a day. One solution.

Gentle on Monday, tough by Sunday. Every puzzle can be solved by reasoning alone: no guessing, no luck.

The same puzzle for everyone

Every player in the world gets the same puzzle on the same day. Solve it, then compare notes with friends.

Three kinds of puzzle

• Futoshiki: fill the grid so that every row and column holds each number once, and every inequality sign holds.
• Skyscrapers: place buildings of different heights. The numbers around the edge tell you how many buildings you can see from each side.
• Suspects: twenty people, some of them criminals. Everyone you clear or catch gives you another clue.

Play your way

Start an extra puzzle of any type whenever you like, catch up on days you missed, and ask for a hint when you're stuck.
