What is the composite score?

The composite score is used to determine the monthly ranking. It is calculated using a formula taking into account three things:

• The average score (the higher the better)
• The average time taken to complete a puzzle (the lower the better)
• The total number of puzzles completed during the month (the higher the better)

For those of you interested, here is the formula we are using:

CS = (AS + 100 * 10^(- AT/25000) + 100 * 10^(-(7*DM-NP)/3000))/3

where:

• CS is the composite score
• AS is the average score
• AT is the average time in seconds
• DM is the number of days in the month
• NP is the number of puzzles completed during the month
