Brain Teasers & Puzzles

Puzzles...     Puzzles???     Puzzles!!!

Some people love them, others hate them. I love them and started collecting them, partly for my students as brain exercises because, according to de Bono:

"Thinking is not a matter of getting the right answer. It is a matter of consciously using your mind, and enjoying using it. Treat thinking like a sport. Have fun.
In sport, coaching makes a big difference. It is the same with thinking."

(Edward de Bono. 1995. Mind Power. Dorling Kindersley.)
