Enter the JPLBC Ladder:

A challenge ladder is a simple, singles competition where members challenge each other to matches to improve their ranking--winners move up the ladder, and losers move down. Over time players are naturally stacked by skill level. It provides a great opportunity for members, novice to veteran, to meet new people, and play other bowlers around their skill level.

The ladder is open to all members, free to play, and runs year round.
