My MLB Career Simulator.

A full baseball life you play in the browser: a Triple-A route, a call-up, then continuous major-league age chapters. Development, the free-agent winter, the September of your last year — all of it lands as a decision, with the season line filling in behind you.

Five seasons, measured across our own archive of completed careers — a little under the five and a half usually quoted, which counts service time differently. Either way the distribution behind it is brutal: a large share of debuts never reach a second season. This board draws from careers that lasted, which is why a full run here looks nothing like the median major leaguer. See how every sport compares.

That first position choice changes the whole career line. Pitchers answer to wins, strikeouts and K/9, with 59 wins and 513 strikeouts on the record bench. Catchers add caught-stealing rate to their power production, while infielders and outfielders pair home runs and RBI with batting average. The hitter bench carries 73 home runs, 191 RBI and a .466 average, with recognized Negro Leagues included.

Because this career begins after amateur acquisition. You start on a Triple-A route and arrive through a call-up rather than receiving a new draft receipt. The opening line shapes your standing and landing environment; the career never invents a draft round that is not part of this stage.

Farm system is where you begin and Call-up is how you arrive. First seasons, Breakthrough, Free agency, Prime years and Veteran years each cover three years of your career. Farewell is the retirement call, and Front office is what you do once the playing is over.

Three-year windows keep a long baseball life legible without flattening it into one average. The rail still shows the rise, free-agent years, prime, veteran phase, and farewell as separate pieces, making peaks and declines easy to locate.

The real single-season records for whichever way you play, and a count of how many of your seasons actually beat one. It sits at zero for almost every career. It is a benchmark from the public record book — never a rating, and never a claim about any particular player.

It is the biggest lever in the game. The offers that land at that checkpoint set your money and your club for the seasons that follow, and the club you pick changes how often October is on the table. Take the deal or bet on yourself — both are real options and both have consequences.

Yes. Postseason opportunities and titles join the player’s own production when the finished career is evaluated. A strong individual line without team success can still matter, but a championship changes how otherwise similar careers compare.

Only by earning it. Honors land when the numbers support them, the finish grades your whole career on an SSS–F ladder, and the plaque follows the run rather than the intention. Most careers do not get there.

The farewell asks whether to extend the run or close it, and a later baseball-operations decision may add one final leadership receipt. It sits beside the playing career rather than adding games, seasons or salary to it.

Nothing, as far as the search box is concerned. Both point at this: a career you play out yourself, one decision at a time, scored against what the record book actually says.

The engine uses the seed and recorded choices in the address to derive the career, without drawing on the clock or ambient randomness. As a result, reopening a completed link reproduces the same teams, seasons, decisions, and final card.

Yes — share the finished card and the challenge opens a brand-new baseball career for them, your result attached as the number to beat.

Neither. It plays in the browser on a phone or a computer, free, and your career lives in the URL, so a refresh or a reopened tab picks up exactly where you left it.

There is — the daily MLB wordle board hides one major leaguer at a time and grades every guess by era, club and that season’s own line, from an archive that starts in 1871. A new name each midnight Eastern; this career game has no such clock.

It does — the NBA career simulator trades the farm system for a college program and draft night, and its board chases scoring seasons the way this one chases batting lines.

It is — the 162-0 game asks a full lineup and rotation to sweep baseball’s entire schedule, where this page spends one arm or one bat across a whole career. The hardest perfect season in American sport, drawn from the same archive back to 1871.
