The world is a giant, confusing puzzle – so you might as well enjoy it. Pocket Planet is a fun jigsaw-puzzle game that will expand your knowledge of geography while driving you slightly nuts trying to find Lesotho. (Yes, it really is a landlocked country shaped something like a well-chewed apple core and completely surrounded by South Africa). Or Andorra, a tiny monarchy wedged between France and Spain and jointly ruled by two co-princes – one of whom is the President of France and the other a Roman Catholic Bishop. Good luck –and we’ll see you in beautiful downtown N'Djamena.
