A Turkish-developed mobile game is making waves across Europe. Referee Simulator, created by İstanbul-based Flat Games and published by Joygame Publishing, has become the #1 simulation game across Europe.
Football Referee Simulator 3D places players in the shoes of a professional football referee, offering a realistic, first-person experience across dynamic 3D match settings. Players are tasked with enforcing the rules of the game—calling fouls, assessing offsides, and awarding penalties—while navigating pressure from players, fans, and match scenarios.
The game features a structured career mode that spans local leagues to international competitions, complete with post-match evaluations, evolving match dynamics, and lifelike reactions from crowds and players.
