Enter all participant names, then run a marble race. The finishing order determines team assignments — odd-numbered finishers go to Team A, even-numbered to Team B. For more teams, split by finishing position (1-5 = Team A, 6-10 = Team B, etc.). This random team generator uses real physics simulation, so the assignment is genuinely unpredictable and fair.
Why use a boring random team picker that just shuffles a list? With Roulette Rush, the team assignment process becomes an event itself. Marbles race through obstacle courses, and the finishing order determines teams. It's transparent, entertaining, and impossible to accuse of bias — everyone watches the physics play out in real-time.
Teachers love using marble racing as a random group generator for students. Enter student names, run the race, and assign groups based on finishing order. Students actually look forward to group assignments when it means watching a marble race. Works on projectors, tablets, and phones with no sign-up needed.
Running a team building event or office activity? Use Roulette Rush as a random team divider for icebreakers, hackathons, or workshop groups. Support for up to 500 participants means it scales from small meetings to large company events. The marble race format breaks the ice before teams even start working together.
