About the Moss Rank

There are many different leaderboards on MossRanking for each of Spelunky Classic, Spelunky HD and Spelunky 2, but they all work in a similar way. Each player's ranking on a given leaderboard is calculated from points that are earned by submitting runs to the categories which define that leaderboard.

For each leaderboard (with a few exceptions, see below), points are awarded in three ways:

Rating Points (R): For each category, a maximum of 100,000 points are available by comparing a player's personal best (PB) to the current world record (WR). More precisely, a rating percentage is calculated from WR/PB for speed categories or PB/WR for score categories. These ratings are then multiplied by 100,000 points each and are awarded per category.
Completion Bonus (C): 5,000 bonus points are awarded for each category a player submits a run to.
Performance Bonus (P): A further 5,000 bonus points are awarded for each category a player submits a run to with a rating of 20% or higher. This means faster than five times the WR for speed categories or greater than one fifth of the WR for score categories.

A player's total points on a given leaderboard is the sum of R+C+P for every category relevant to that leaderboard. Note that for subrankings (leaderboards without "Main" in the title), the final total is divided by 10.

Exemptions

A ranking can be comprised of multiple groups of categories and within each group a number of exemptions are allowed. Note that all categories still award bonus points.

Challenge Rankings

Rating Points (R): Rating points award a maximum of 10,000.
Completion Bonus (C): 90,000 bonus points are awarded for each category a player submits a run to.
Performance Bonus (P): Performance bonuses are not included.

After submitting a run, MossRanking will update within 10 minutes. This includes new runs, rankings, subrankings, player profiles, daily top 10, daily average and daily high score.
