It’s funny that football/soccer has spent a century optimizing tactics, boots, VAR...
yet we still keep experimenting so much with the geometry of the ball. How have we not found the ideal number of panels?

FIFA World Cup ball comparison
Trionda (2026) vs Al Rihla (2022)
This CFD comparison is showing two different FIFA World Cup ball designs spinning at the same rate (600 rpm) in the same airflow (30 m/s).
The colours and wake structure reveal how the surface geometry affects the air around the ball.
* Trionda (2026): Much more intricate surface pattern with many grooves, ridges and dimples.
* Al Rihla (2022): Simpler panel layout with fewer aerodynamic features.
players might notice the Trionda:
* Grips the air more strongly
* Curves more readily when spun
* Feel slightly more stable aerodynamically
The 2026 Trionda appears designed to give the airflow more to “hold onto”, creating stronger vortex structures and slightly larger aerodynamic forces than the smoother 2022 Al Rihla, which may translate into more pronounced curl and control for skilled players.

#Esperanto appears on the official ball of the #WorldCup, the "Al Rihla Pro" by @adidas, alongside English, Chinese, Arabic, Spanish and French! It reads: "Football is: Teamwork - Fair play - Collective Responsibility - Passion - Respect." #alrihla #fifa #fifaworldcup #FIFAWorldCupQatar2022 #fifaworldcup2022 #FIFA2022
