To determine if someone is a puzzle-solving fanatic, you must ask yourself these questions: Do they sit for hours - even days - absorbed in a puzzle, perhaps refusing food and drinks? Have they solved nearly every puzzle available? If you have answered 'yes' to the above questions, then they are, indeed, a serious puzzling maniac. Unfortunately, there is no cure for this. Their only hope is the Mini Tetris Cube. It is has over 9,000 solutions - and is extremely addictive. When given to the puzzle obsessed it will, at first, engross them. But then, when they discover that it is not as easy to solve as it looks, they may lose their appetite for puzzling - muttering something like, 'I think it's high time for a new hobby'. At this point they will place the unsolved Mini Tetris Cube aside and may join the local knitting group.
