IIT Madras Introduces 'Phiball', a Three-Team Basketball Variant for Grassroots Sports

The Indian Institute of Technology (IIT) Madras has launched Phiball, a new three-team basketball variant played on a circular court. Unveiled on the eve of National Sports Day, the sport is designed to encourage faster decisions, intense competition, and affordable grassroots participation.

Prof Sathyanarayana N Gummadi, Dean of Students at IIT Madras, stated that the format combines elements of basketball and netball. The game features three teams competing simultaneously on a single circular pitch with a 26-metre diameter. According to the developers, the American invention Omegaball—a modified three-sided version of football introduced by IIT Madras in April—inspired the creation of Phiball.

It took the institute two months of consultation with basketball coaches to establish the rules. Because basketball has wider acceptance in Indian schools and colleges than football, the team adapted the multi-team concept for the sport. The format utilizes a 24-second shot clock and limits individual ball handling to three dribbles per possession, forcing players to pass quickly.

The design alters traditional basketball mechanics significantly. The court features a 1.6-metre restricted perimeter zone, named after the Golden Ratio or Phi, intended to cushion collisions. Furthermore, the baskets lack backboards, meaning layups and bank shots are not possible, and players must aim directly for the rim. Stepping into the No-Offense Zone directly beneath the net immediately nullifies any scored point.

A key focus of Phiball is accessibility and low infrastructure cost. Traditional synthetic and concrete courts are often cost-prohibitive for rural and government schools. In contrast, Phiball can be set up on dirt, clay, or grass using a rope, chalk, brightly colored yellow tape, plastic cones, and three portable, backboard-less rims. Establishing the game requires a total setup cost of under Rs 30,000.

During the inaugural matches, which saw participation from students including teams from VIT Chennai and A M Jain College, players adapted to the spatial and defensive challenges of tracking multiple rims simultaneously. When rain interrupted outdoor play, the game was easily moved indoors, demonstrating the format's adaptability for resource-constrained environments.

"The launch of Phiball by IIT Madras highlights a practical approach to addressing infrastructure gaps in grassroots sports and recreation. By stripping away the need for expensive synthetic courts and standardizing setup costs to under Rs 30,000, the institution has created an accessible model that could inspire grassroots sports innovation and entrepreneurship. Scalable, low-cost solutions are essential for increasing participation in developing markets, and this initiative demonstrates how clever design can overcome capital constraints in the sports sector." — Dr. Shishir Gupta, Founder & CEO, StartupLanes
