One shared challenge
A fresh MLB challenge is generated every day.
Daily streak
One daily run in any sport keeps the chain alive.
Spin. Pick.
Survive.
Here you spin for a storied franchise season, draft a seven-man lineup from pitchers to outfielders, and run the full 162. Most squads settle into a pennant race; a great one chases the 116-win teams of legend; and somewhere out there is a roster and a seed that never loses at all.

Share the receipt
Your record, lineup and seed travel together, so every shared result is genuine.
Your lineup covers seven slots: a starting pitcher, a relief pitcher, a catcher, two infielders and two outfielders. Every pick begins with team and season reels. The landed combination identifies an exact historical roster, then you choose an eligible player for the open slot. Fully modelled seasons expose the whole eligible squad; some older records use a focused position shortlist.
Easy gives three re-rolls, Normal one, and Hard none while hiding ratings. Era filters let you focus on a decade or use the full archive. That makes roster construction more than a hunt for the biggest number: real teammates add chemistry, and using a reroll too early can leave a weak position exposed later.
The simulation then grinds through all 162 games, each one a win or a loss. Sweep the entire schedule and you reach the summit: IMMORTAL — 162-0. Win 70% or more and you are on 116-WIN PACE, matching the greatest regular seasons ever recorded; below that sit World Series, Division Title, Wild Card and Winning Record, with the Cellar Dwellers tier waiting if it all goes wrong. Chemistry links between real teammates strengthen your roster, and the seeded engine guarantees that a shared season replays exactly as it happened.
What never changes
Same squad.
Same seed.
Same result.
You cannot quietly re-run a bad season. The share link is the receipt.
Legendary MLB squads
Every spin lands on a real team and season. These are some of the era-defining rosters already waiting in the pool.
162‑0
No losses across the full season
The regular-season record book tops out at 116 wins, and it has been reached twice. The 1906 Chicago Cubs went 116-36 — still the best winning percentage in modern MLB history — and then lost the World Series to the crosstown White Sox. Ninety-five years later the 2001 Seattle Mariners matched them at 116-46, only to fall in the playoffs without ever reaching the World Series.
That is the sobering context for a 162-0 chase: the two winningest regular-season teams ever still lost 36 and 46 games respectively, and neither finished the year as champion. Baseball has never seen anything resembling perfection — your simulation might.

No account, no hidden re-simulation and no hour-long tutorial. Pick the rules, build the roster and let the season answer the argument.
Has any MLB team ever gone undefeated?
No — and no team has ever been close. The best regular seasons in MLB history are the 1906 Cubs at 116-36 and the 2001 Mariners at 116-46, meaning even the all-time greats lost dozens of games.
What is the most wins in an MLB season?
116, achieved twice: by the 1906 Chicago Cubs (116-36) and the 2001 Seattle Mariners (116-46). Remarkably, neither team won the World Series that year.
Why do I only draft seven players?
The lineup is a condensed diamond: one starting pitcher, one reliever, a catcher, two infielders and two outfielders. Seven picks keep the draft quick while still covering every part of the field.
Is every simulated season different?
Every new draft generates a fresh seed, so yes — but any single result is permanent. The seed plus your exact lineup always reproduces the same 162-game campaign, which keeps shared results honest.
