Mindtrapped

Recently someone passed this game on to me. I love games like this but I cannot figure out how to play the game properly!! There's no instructions (as you can probably tell from the photo, the game is pretty old now and is probably third or fourth-hand as opposed to second!) and the score cards included with the game are little to go on. It really doesn't matter though, because I can just sit and read the cards all day long. Sad right? But the game is based on riddles and brain teasers and can keep me entertained for hours, right up my street! :-)
