I was introduced to this game over the weekend and it left me stumped.  At the time, I blamed the beer and moved on to something else.  Not having solved it was still nagging at me today, so off to the internet to find some online versions.  No, it wasn’t the beer; I still couldn’t figure it out.  But these were the best websites:

• Bill Gates and… tells a nice little story about the game, and gives examples of how it works.
• Mycariboo.com’s version is interactive and works well.
• My favorite is this Flash version.

It’s simple to play: just roll the dice and guess the answer.  The interactive versions will tell you if you are correct.  Repeat until solved.  I only wasted a couple of hours before I got it.
