In the summer of 2003 in St. Louis, the two ball challenge leagues started. These were sport leagues that limited the bowlers to using two bowling balls. It also had a specialized format. This is where BowlSpot.com got involved and created an online league management utility. The league has evovled since then, and so has our software. If you have a unique format league and need something to manage it with, let us know, we may be able to work something out with you.
