The MBC was originally managed on a nearly monthly basis between 2013 and 2015 and was followed by hiatus until 2020. The first 12 iterations of the MBC can be found on the Contests article. The results for the 13th iteration can be found on its news post.
Since 2020, the MBC has adopted a new schedule, ruleset, voting procedure, and reward scheme. The rest of this article details the current format for Monthly Beatmapping Contests.
The timeline for each month's contest is as follows:
The judging portion of each contest overlaps with the next month's contest's beatmapping portion.
Submissions for the MBC must abide by the following rules:
.oszformat. Storyboarded content will not be considered.
One or more rules may be added or dropped depending on the month's specifications. Any exceptions will be clearly explained in the contest's announcement post.
Results for the MBC are first narrowed down to the most competitive entries, then evaluated by a team of judges. Creators of all entries are anonymous in the screening and judging stages.
A group of at least 10 experienced beatmappers (screening crew) are tasked with reviewing all entries and providing their top picks in order of preference. Entries that receive the most praise from the screening crew will move on to the judging stage.
The amount of beatmaps that advance to the judging stage varies depending on the amount of highly competitive submissions the contest receives and will usually range between 5 and 10 finalists.
Another group of at least 5 beatmappers (judges) are tasked with judging the finalists chosen by the screening crew. Only the top entries chosen by screeners reach the judging stage because of the contest's tight schedule.
Judges disect each submission and provide ratings for categories to determine the contest's winner and runner-up.
For each submission, the sum of categories is a judge's raw score. A judge's final score for each submission is calculated as follows:
judge X's final score = (judge X's raw score - judge X's average raw score) / judge X's standard deviation
A submission's score is the sum of each judge's final score. Scores are determined this way to avoid variations in score ranges between judges, as popularized by the Pending Cup.
Due to potential vote manipulation and low voter turnout, the "Voting" aspect of the MBC has been replaced with "Judging" from June 2020 onwards. Community vote may return if those problems can be solved!
In contests before June 2020, voting took place on the respective contest's Community Contests page. Users were encouraged to vote for their favourite entries and to prioritize those that effectively worked with the month's beatmapping limitation.
Information and results for all iterations of the MBC since its relaunch in 2020 can be found below.
