To mark a summer of sport, Rob and Andrew have smashed it out of the park by serving up a sports-themed episode for the season finale.

Including some great puzzles, a maths joke from a crowd song, one of the most costly cricket shots of all time, and as usual some smashing (or perhaps 'knockout'?) puzzles.

Game, set and Maths.

In this very special episode, Rob and Andrew travel to what could arguably be called the spiritual home of Puzzling Maths: Bletchley Park. This extraordinary place was the birthplace of modern computing, and the workplace of Alan Turing and the famous Codebreakers.

We'd love to tell you more, but for reasons of national security the contents of this episode are classified, so ON NO ACCOUNT should you listen.*

*Unless you want to.

Enjoy, we pray thee, this very special edition of the podcast that comes trippingly off the tongue, recorded live in Stratford Upon Avon. Preparest thou to be mightily entertained by such weighty topics as pencils, bridges and Caesar salads, and enjoy trying to spot the Shakespearean references, some more gratuitous than others.

(Sharp-eared listeners might even spot the moment that Andrew and Rob were interrupted by a huge fan, though sadly it was a noisy electric one rather than an actual human.)
