Along with Mind Boggler is the game that came with the 48K spectrum: Pangolins AKA Animals. It's not really the game I'm supplying here -- if you bought a Speccy you should have it already, but it is all the data with it that is the key thing here. I saved it because it contains such a lot of family memories for me: each question in there (except the first few supplied with the game) was filled-in by one of the family or by a friend, and it was at Christmas time we were playing with it, so as soon as I see a question come-up it takes me right back to that moment. I wonder with all the questions we put in, if it can guess the animal you're thinking of :-)
