One footballer, a whole career
Create a player at sixteen, choose an academy, then make season decisions until retirement at thirty-eight. Training, club competition, coach trust, injuries and transfers connect one year to the next.
Original rules and fictional clubs
Every club, league, salary and trophy in Copero is fictional. The position-weighted rating model and legacy rules are published so that you can understand the results. Nationality personalises your player; international tournaments are not simulated.
Free, local and multilingual
No payment or account is needed. Your save stays in this browser. You can play in Spanish, English, Italian, Portuguese, Simplified Chinese or German, and change language without resetting a saved career.
An independent entertainment game
Copero is not affiliated with a real club, league or governing body. It does not broadcast matches, provide live football data, use generative AI, or predict sporting results. Quizzes, multiplayer and leaderboards are not included in this edition.
