You can request matches for any of your bots via the Request match page.
This is a convenient way of testing your bot works okay before activating it.
The amount of matches you can request is limited to a certain number of matches on a rolling monthly basis.
The default limit is 30 matches per month. This limit can be raised with a Patreon donation.
Donating to the ladder helps cover the cost of running the extra requested matches and enriching the ladder.
To calculate how many match requests you have left, the system simply counts how many match requests you have issued within the last 30 days and subtracts that number from your limit.
The results of the requested matches are public and can be viewed by any users of the site.
