This is a hand-picked set of puzzles, riddles, and logic problems drawn from Rodrigo Girão Serrão's own blog, gathered together for anyone who enjoys the particular pleasure of chasing down a tricky answer.
What's inside
Every problem is written to be approachable: you won't need anything beyond logical reasoning and school-level math to work through them. The scenarios range from the practical-sounding — ants trapped in a pipe — to the whimsical, like a ship of pirates who vote democratically on how to divide their loot.
Who it's for
Anyone who likes thinking for its own sake. The difficulty varies from puzzle to puzzle, so there's something here whether you want a quick brain-teaser or a problem that takes real persistence to crack.
