Logo matchstick puzzle 
Here's our logo, the W pentomino, subdivided into its 5 component squares. This diagram consists of 16 unitlength sticks. You can use matchsticks or toothpicks for working these puzzles.
Morphing Pentominoes There are 12 shapes made of 5 squares each. What is the minimum number of moves for each case of turning the W into any of the 11 others, shown below? (Seven of them are covered in the list above!) Which one pentomino is formed by omitting one stick altogether? 

Bonus question: What is the fewest number of moves to form all 12 pentominoes, transforming each into the next and ending with the one that omits one stick? Can you beat 28? Send us your best result and you may win a prize. Email to: Pentomino Parade.
