Spin for a team. Spin for a decade. Draft a legend.
Each round, the slot machine lands on an MLB franchise and a decade. You draft one player from that team & era to fill an open spot in your lineup. Fill all 9 positions — then the engine simulates your season.
Can you build a roster good enough to go a perfect 162–0? (Spoiler: it's brutal.)
Casual: stats shown, and a real shot at a perfect season (~1 in 5,000). Pro: stats hidden — draft from memory — and 162-0 is brutally rare (~1 in 100,000). For purists.

The goal: assemble a 9-position MLB lineup capable of an impossible undefeated 162-game season.
WAR (Wins Above Replacement) is each player's peak value in that decade, era-adjusted. Stack the highest-WAR legends and you might flirt with 140+ wins. A flawless roster can even reach a perfect 162-0 — about 1 in 5,000 in Casual, and a brutal ~1 in 100,000 in Pro. Casual and Pro keep separate leaderboards.
Challenge a friend: after you simulate, hit Challenge a friend to copy a code (or link). They paste it in on the start screen, build their own lineup, and the game declares a winner — most wins takes it, total WAR breaks ties.
