The genre, played straight
The perfect season game
Draft an all-time roster from real franchise eras, then survive a full simulated season. Win out — every game, playoffs included — and you join the immortals. About 1 in 20 boards do.
How an undefeated run actually works
Each round spins up one franchise era — a city and a window of years, anywhere back to 1966 — and lays out that era’s whole squad with real season statistics on every card. You pick a player, choose his seat, and move on. Twelve seats later the season simulates week by week: your roster’s era-fair ratings drive a win probability, the weakest seat drags hardest, and a single playoff loss ends the run.
Why era-fair ratings matter
An all-time game is only as honest as its cross-era math. Every player-season here is rated against its own era from the public record — statistics, honors, results — so a 1962 linebacker and a 2024 edge rusher can share a board without either being a trap pick. The method is public: how the ratings work.
Three sports, one game
Football is the flagship — twelve seats, twenty games, a shared Daily Challenge with streaks. Basketball runs ten seats through a 98-game gauntlet. Baseball is the deep end: a lineup and a rotation against 162 games, with franchise eras back to 1871.
Questions people actually ask
What is a perfect season game?
A roster-building game where you draft an all-time team under constraints — here, one random franchise era per round — and a simulated season decides whether you run the table. Going undefeated is the trophy; the grade ladder below it is the game.
How rare is a perfect season?
On this board, roughly 1 in 20 finished runs goes perfect. The difficulty is tuned openly against the rating math — the curve is published on the how-ratings-work page — so a perfect season stays a real achievement rather than a participation stamp.
Is it luck or skill?
Both, honestly. The eras you spin are luck; what you do with a loaded round — which seat you spend it on, when to burn a re-roll, how you protect your weakest seat — is skill. The weak-link math means one bad seat drags the whole roster.
Which sports can I play?
Football is the flagship, with a shared Daily Challenge. Basketball plays ten seats against a 98-game gauntlet, and baseball fields a full lineup and rotation against 162 games, with eras back to 1871.
