Students can choose to submit their scores online and measure up with other MathLanders users in daily or weekly competitions. Standings are provided based on number of points accumulated by each student.

Correct answers are awarded certain number of points, depending on the difficulty of the solved quiz. Wrong answers are not penalized in points. Therefore, the daily and weekly competitions account only for the amount of work performed by the students, regardless of their grade, since the main purpose of the MathLanders program is to motivate students for more math work.

Team competitions run from Monday to Sunday, each week. Students can team up with their friends, to compete against other rival teams.

During the week, the students can create their own teams, or join somebody else's team, or move from a team to another. Transfers from one team to another are allowed freely until Friday, when the teams are closed for transfers. The competition continues however until Sunday, at the end of the day.

Students contribute their own points to add them up to the overall team score. At the end of the week, the team with most number of points is declared the champion team of the week.

Messages can be exchanged between students. The messaging system is especially useful for team enrolments, when students are recruited by team owners and communication between students is necessary.

A forum is also available, on various topics, mostly related to math. All student's messages and forum entries are saved locally on student's computer for parent review.

User privacy during online activities is important in MathLanders. No personal information is exchanged online. Only score and program use data is sent by the user.

Even then, since MathLanders is run on users' computers rather than on the server, the online competitions are only visible within the MathLanders application, and not on the website.
