Monthly IIDX Accuracy Arena

A monthly Beatmania IIDX high scoring contest made possible by Boons!

Compete monthly across 3 brackets for the highest score on 6 different charts!
There is a bracket for every level of proficiency (and of course you can participate in higher brackets, you might surprise yourself!)

• Lower bracket: For players who are on their way to mastering the basics – level 2 to 6 (up to 5th dan)
• Upper bracket: For more experienced players – level 7 to 10 (5th to 8th dan)
• Master bracket: For advanced players who need an extra challenge – level 10 and 11 (9th dan and up)

How scoring works

For each chart, you’ll receive a rating based on how your score compares to the scores of other participants. Your final ranking is determined by the weighted average of your ratings across all six charts.
