The rankings are broken up into two main sections: the groups on the left and the Who's Hot list.
The groups on the left are calculated using a player's total points earned divided by the total number of points possible since the dawn of Iron Sudoku.
Elite: Players who have completed every single puzzle
Experts: Players who have earned more than 90% of the total possible points
Pros: Players who have earned more than 50% of the total possible points
Regulars: Players who have earned more than 25% of the total possible points
Newbies: Players who have earned more than 5% of the total possible points
Who's Hot: This list shows the top 200 point totals earned by players over the past 2 weeks.
