You may submit up to 3 scores in a day to earn Neopoints and to be listed on the high score table. This is called maxing out for a day. Even after maxing out, you can continue to play multiple times and submit scores till you reach a certain cap limit. This cap limit is in proportion to the points you will need to achieve the next ranking for you to reach All-Star. This will also add to your team's performance in the tournament and earn you Prize Shop credits. However, after maxing out, you cannot earn Neopoints.
Once you reach the cap limit, take a break for the day and return the next day to get back on your journey to make your team victorious!
