When running a ladder in the TennisRungs platform, users may have two options to create a match depending on the ladder setup you chose.
First let me explain the difference between the "competitive" ladder types and the "social" ladder types. If you notice when you create a ladder, you can setup a ladder to be 1 of 3 types (Bump, Swap or Points-Based). An explanation of these ladder types can be found in this article.
When running a ladder with a BUMP or SWAMP algorithm ONLY direct challenges can be made. These ranking rules are best suited for very competitive club-based ladders.
For those wanting a more "social" feel and the ability to allow their players to play more matches, you will want to setup a "Points-Based" Ladder. When you do this, players can simply "PROPOSE" an open match on a particular Date/Time and/or Location. Other players on this ladder will then be alerted via email and can ACCEPT the proposal. This can be done by a player by clicking the PROPOSE MATCH button.
When scores are reported for Points-Based ladders, players are awarded POINTS based on how you set these factors up when setting up the ladder.
The players are then ranked from the highest point total down.
