How to play
Each round is a slot machine
You get a random team and a random decade — that's it. The whole qualifying roster of position players (or pitchers, in the later rounds) shows up. You decide who to pick and what slot to fill them at.
Multi-position eligibility
Players list every position they played meaningfully — Mookie Betts can fill RF, CF, 2B, or DH; Ben Zobrist can fill almost anywhere. When the player has more than one open slot they can fill, you choose where to put them.
Thirteen slots, two phases
First nine rounds: position players. The infield, outfield, and designated hitter. Then four rounds of pitchers: three starters and a closer. The order within each phase is up to you.
Two skips per game
One team skip and one decade skip. Use them when the slot rolls into an era or franchise that won't give you what you need. They re-roll just the team or decade, not both.
Five decades minimum
Your final roster must span at least five distinct decades for the simulation to run. Piling on one era is a disqualification, not a loss.
One number: WAR
A replacement-level team wins about 48 games out of 162. Every win above that comes from a real player's contribution, measured in Wins Above Replacement. We sum your roster's bWAR (from Baseball-Reference's historical archive) and add it to that 48. To go 162-0 you need 114 WAR spread across thirteen players.
What counts as a peak
For each player, the slot machine offers their peak qualifying season with that franchise in that decade — peak by OPS+ for hitters, by ERA+ for starters, by saves for closers. So Mickey Mantle in the Yankees · 1960s is his 1961 line; Pedro on the Red Sox · 2000s is his 2000.
