The whole world's gone Pokémon mad. Well here's another city-wide treasure hunt game for you. It doesn't rely on smartphones, and you don't have to do anything lewd-sounding, like powering up your Squirtle.
The Big Letter Hunt is all about spotting a hidden alphabet in the city's buildings. The London Eye is a giant letter Q. The Liberty building conceals a timber R, while the Brunswick Centre sports a multistorey N.
This is a book that invites you to look at the city in a different light. You might find all 26 letters fairly quickly, but while doing so you'll gain a new appreciation of the architecture around you.
The book works best as a family activity — a terrific way to get kids exploring the city without resorting to Japanese monsters.
Big Letter Hunt by Amandine Alessandra and Rute Nieto Ferreira is out now from Batsford.
