Puzzles and Humour

I like mathematical puzzles (and mathematical humour).

They provide intellectual challenges and mental stimulation. They also help the puzzler to learn and develop good problem-solving techniques. These techniques can sometimes be used when solving strategy problems in real life and can certainly be used in other mathematical pursuits. I have hundreds, and possibly thousands, of puzzles to share with you. This represents a small start!

I have decided to bundle them in groups of twenty:
