Rogelito Ballon created the game Volleyproblem to promote math skills, teamwork, and confidence among students. The game is played between two teams of six players each across a dividing line. A coin toss determines the topic and serving team. The objective is to serve math questions to the opposing team, scoring a point if the question is answered incorrectly or remains unanswered for 3 minutes. Each team takes turns serving and answering questions, with the goal of being the first to 9 points to win the match. The referee verifies answers privately before questions are served to maintain an educational and friendly competition.
