How it works
Spin for an era
Each round spins a decade of baseball history — the 1950s through the 2020s — and hands you a small pool of original, fictional candidates from it.
Draft nine by position
Build a lineup and rotation across nine rounds. Era chemistry rewards rosters whose players actually belong to the same baseball.
Survive 162 games
An era-accurate season plays out game by game — home-field, fatigue over the long grind, injuries, and matchup swings all in play. Drop zero and you go 162-0.
What "162-0" actually means
162-0 is a free baseball roster-building game: spin for an era, draft nine players by position across nine rounds, and simulate a full season to see how far your roster gets. The name comes from the longest regular season in North American team sports — 162 games — and the number no team has ever reached: zero losses across all of them.
The closest anyone has come is nowhere close. The 2001 Seattle Mariners won 116 games and still lost 46. The 1906 Chicago Cubs went 116-36 across a 154-game schedule. A single hot week can carry a football team to an undefeated season; baseball's 162-game grind almost guarantees a bad night eventually. That's exactly what makes 162-0 the sport's ultimate what-if. See our breakdown of why a perfect season is effectively impossible.
The season is simulated game by game
Every one of your 162 games is its own simulated result, tuned to baseball's run-scoring scale — think 4-to-5 runs a game, frequent one- and two-run finishes, and the occasional shutout. Home-field, roster fatigue as the season wears on, injury risk, and opponent matchup tags (power-heavy lineups, pitching-heavy staffs, speed-and-defense clubs) all push individual games one way or the other.
The era is baked into everything
Baseball hasn't always scored the same way. The 1960s was a pitcher's decade with a raised mound and huge strike zones; the 1990s and 2000s saw offense surge; the 2010s brought the launch-angle, strikeout-and-homer game. Your roster's era sets the run environment and how much your hitting, pitching, and defense actually swing results — and it sets the schedule length: 154 games for a 1950s club, 162 for every decade after.
Guides

What is 162-0?
A free browser game: spin for a decade of baseball history, draft nine players — one per position across the lineup and rotation — then simulate a full season and see how close you get to a perfect record. "162-0" is what a truly flawless modern MLB season would look like: winning every single one of the 162 regular-season games. No real team has ever done it.
Has any MLB team actually gone 162-0?
No. In the 162-game era (since 1961–62), the best regular season ever was the 2001 Seattle Mariners at 116-46, tied with the 1906 Chicago Cubs for the most wins in a season (the Cubs went 116-36 in a 154-game schedule). Even those all-time teams lost dozens of games. A perfect 162-0 has never happened and is treated as effectively impossible over so long a season.
Is 162-0 free to play?
Yes, entirely free, with no account required to play, save progress, or submit to the leaderboard.
How many players do you draft?
Nine picks total, one per slot — building out a lineup and rotation. Each round spins a decade of baseball history and hands you a small pool of original, fictional candidates to choose from.
Does the schedule length change by era?
Yes. MLB played a 154-game schedule through the 1950s, then expanded to 162 games from the 1961–62 expansion onward. If your roster represents the 1950s, the simulation plays a 154-game season; every later decade plays the full 162. Strike- and pandemic-shortened one-off years are not modeled at this decade-level granularity.
Do the eras actually play differently?
Yes. Each decade carries its own modifiers. The 1960s is the pitching-dominant "Year of the Pitcher" low-scoring era; the 1990s and 2000s are high-offense; the 2010s reflects the launch-angle, strikeout-and-homer game; the 2020s leans back toward speed and defense. Those modifiers shift run-scoring and how much your hitting, pitching, and defense matter.
Is there a Daily Challenge and leaderboard?
Yes. Everyone who plays on the same day gets the exact same sequence of draft options, and you can submit your season result to a live, public leaderboard — no account required.
Can I replay a friend's exact draft?
Yes. Every run generates a shareable seed. Enter someone else's seed on the welcome screen and you'll get the exact same sequence of draft options they had — make the same picks for a mirror match, or different picks for a real head-to-head comparison.
