34-0-0 is a free, unofficial fan game for football supporters who want to test their knowledge of Bundesliga clubs, eras, and players. Players spin to draw a real club and era, then choose one player from each squad to build an 11-player team. Once the lineup is complete, the game projects how it might perform over a full 34-match Bundesliga season, including the chance of achieving the never-before-seen record of 34 wins, no draws, and no losses.

The game offers several formations, including 4-3-3, 4-4-2, and 3-5-2, alongside different ways to play. Herbstmeister uses a 17-game season, Expert hides player ratings during drafting, and Hardcore ends a run after any draw or loss. The arcade-style Gauntlet challenges players to survive increasingly difficult clubs, with limited lives, rising scores, and a boss every five wins. Players can also explore Bundesliga legends, records, historic eras, and rivalries, then share or save a team card.
