To earn your belts, you must play in Competition Mode and defeat many opponents. As you keep earning more belts, you have to start defeating more people. There are a total of nine belts that you can earn. Like I said, you earn a belt after you win a certain amount of times. Here is a chart that shows you how many wins you need to earn your next belt (credit to Chrisdog93). White belt - 5 total wins needed. Yellow belt - 13 total wins needed. Orange belt - 21 total wins needed. Green belt - 30 total wins needed. Blue belt - 40 total wins needed. Red belt - 52 total wins needed. Purple belt - 64 total wins needed. Brown belt - 76 total wins needed. Black belt - 88 total wins needed. Remember - they are total wins. You do not need to win all of those times in a row.
The first belt you earn is your Red belt, the next is gold, then blue, then brown, then black. After you have reached your black belt you can then earn Dans
you have to win 5 or 6 time it depends on how good you do it
