About

brainteaser.club is a series of 42 logic and maths riddles: great classics, and a few lesser-known puzzles.

Robin writes them. Ines draws them, in ink and flat colour.

A new riddle goes out every Thursday on Instagram, @brainteaser.club. This site publishes the same riddles, in French and English, for anyone who isn’t on Instagram. There’s also an RSS feed.

A book will follow.
