About the 8-0 World Cup challenge

84-0's World Cup mode is a free browser game where you draft an all-time World Cup roster one random draw at a time. Build an all-time national side and chase a perfect 8-0 World Cup run.

Each draw offers players from a random team and era, and you keep exactly one — build the strongest possible lineup, then watch the simulation play out. One loss ends the run, so a true 8-0 season is genuinely rare.

Tips from the community

• Spend your skips early rather than hoarding them, keep roster slots flexible so a late superstar always has a home, and mind era adjustments — a dominant modern season usually beats bigger raw numbers from early eras.
• Study the league leaders after each sim — the engine rewards balanced rosters over one superstar.
• Signed-in runs count toward weekly and monthly leaderboard prizes.
