The Ordnance Survey Puzzle Tour of Britain
Covering 40 regional maps from across the entire country, this book has hundreds of puzzles to complete. There are mind-boggling brainteasers, navigational challenges, word games, code-crackers, anagrams and mathematical conundrums to solve, plus random information on local history, folklore and activities.
The puzzles are split into Easy, Medium, Tricky and Challenging levels - and the answers are included at the back for those times you do get stuck. The maps include both modern and historical versions to work from. Alongside the maps are pages of interesting titbits of local knowledge, the origins of place names and some obscure historical events.
