About 7a0

A World Cup dream-team challenge

7a0 is an independent browser game where you draw historic national teams, select players who appeared for those squads, complete a legal starting XI and simulate a tournament run. The central challenge is simple: build a team strong enough to finish with a perfect 7–0 record.

The game is designed for football supporters who enjoy comparing eras, remembering tournament squads and making difficult lineup choices. It can be played directly in a modern web browser without creating an account.

Who publishes 7a0

The publisher of this website is 7a0.online, also written Sete a Zero. The same site publishes the playable game, the historical World Cup archive guides, the data methodology and the privacy and legal pages.

7a0.online is the public name of the independent project. There is no parent football organization behind the site. Editorial decisions about which squads receive standalone guides, how players are rated for the game and how the simulator behaves are made by the 7a0.online publisher.

The historical archive

The playable archive is assembled from historical World Cup squad records represented in the 7a0 data set. It includes hundreds of national-team squads across multiple tournament editions, with player names, shirt numbers, positions and game ratings used by the lineup builder and simulation engine.

Historical names, squads and tournament facts are informational references. Editorial summaries, player ratings, legend labels and simulation values are independent judgments created for the game and may be corrected or adjusted over time.

How the simulation should be understood

7a0 is an entertainment product, not an official football model or a prediction service. Match outcomes are produced by the game's own deterministic and randomized rules, using lineup strength, tactical choices and a generated seed.

A result inside 7a0 does not claim that one real player, team or football generation was objectively better than another. The simulation is intended to make squad-building decisions replayable and fun.
