ThinkFun is one of the best puzzle companies in the world.  I was honored to be asked to create the challenge puzzles for their new game Thinking Putty Puzzles.  The concept is easy: connect the two yellow points, and the two blue points, etc, without crossing lines.
 However, in this version, there are bridges, which allow for some crossing of lines!
When's the last time you played with putty" Parenting Progress wrote a very nice review of the game. Read it here.

Reasons to buy:
1. It's fun.
2. Makes for a great gift for nieces/nephews/grandkids. It's a known fact that purchasing puzzles will make children love you more.
3. My royalty checks will increase with your purchase.
