Referee
Simulator

A football referee career game: from amateur leagues to the World Cup final. I designed the core loop, the referee stat system, the VAR economy and the meta layer, then turned the same positions into the playables and UA videos above.

Referee stats

The referee is a dot you steer with a joystick over a 2D match simulation. Stamina drains as you move, and speed and view field shrink faster as it drops. Stay close to the play to see the 3D position up close.

02 — Economy

VAR as a sink

The first look at a position is free. Replays and extra camera angles cost coins, so accuracy is something you pay for. Energy gates sessions, and rewarded video refills it.

  • VAR replay + timeline10
  • Camera 2+15
  • Camera 3+25
  • Match entry20 energy
  • Coins per matchrating × 6

Tuned with a 500-player Python simulation so the coin budget hovers around 50–65 and every camera tier gets used.

03 — Meta

Phone & mini games

Between matches the phone rings: club presidents offer bribes for a red card or a penalty, and brands offer sponsorship mini-games. Accepting pays coins but costs reputation. Trivia and match betting open level by level.
