Almost What It SaysScore: 4/5
I liked the book. It's pretty much what it says - a lot of bets that are simple to describe but which are difficult to do or have a certain element of trickery about them.
They're not all certainties though. Some of the bets I figured out without reading the rest of the text, some I'm reasonably confident I'd have figured out, and some descend to such a level of pedantry that I'd be reluctant to mention them to people.
But mostly, yeah, they're fun to read, fun to think about, and maybe fun to try out.
