Al Carlson, manager of a guitar studio around North Bay, Canada, author of the How and Why Guitar System, and engineer-producer behind The Brazillion Girls, invented an abstract game called “Bump and Jump” which he’s now trying to sell.

His impetus for inventing the game, which is “similar to checkers and chess,” is that he thinks players like to jump pieces but don’t like to lose them. No real information is provided about the game in the source, but it sounds a lot like Chinese Checkers.

$1 of each sale is donated to benefit autistic children.
