Timeless Baseball League · rules manual
How to play
TBL is head-to-head fantasy baseball played with real single-season cards. You draft performances that actually happened — Pedro Martinez 2000, Barry Bonds 2001, Rickey Henderson's best legs — and the sim replays them one game a night.
1 · Open a league
A commissioner starts the league and sets the rules: two to twelve teams, season length in weeks, games per week, roster template, which of the eleven categories are scored, waiver rule, playoff field and card era.
The wizard finishes by scheduling the draft date and time and a pick clock. Everyone gets a join code and an invite link.
2 · Claim your club
Owners sign in, enter the join code and name their club — default names are Team 1, Team 2 and so on, and can be changed any time before the draft.
Unclaimed seats stay in the league and are run by the computer, so a six-team league still works with three humans.
3 · Snake draft the legends
Drafting is human-first. When the clock hits your turn you pick from the live card pool, sortable by AVG, OPS, HR for hitters and IP, K, WHIP, ERA for pitchers.
Order snakes each round. Any owner can flip on autodraft for their seat, and a missed clock triggers a best-available pick for the slot that still needs filling.
4 · Set your lineup
The lineup editor controls the batting order and the starting rotation. Batting slot matters: leadoff cards take more plate appearances over a week, and your rotation determines which arms draw starts in the series.
5 · One game a night
At 3:00 AM Eastern the sim plays the next game of the week for every active league. Nothing to click — check the box score with your coffee.
When the series ends the week is scored category by category. Win more categories than your opponent and you take the week.
6 · Waivers, trades and the postseason
Waivers add free agents under the commissioner's rule — strict like-for-like, flexible within hitters and arms, or locked for the whole season. Trades need both owners to confirm, and roster legality is enforced on both sides.
After the regular season the top seeds meet in a single-elimination bracket. Power rankings and season awards run all year for the story around the standings.
Common questions
- Do I need an account to try it?
- No. The solo sandbox runs an auto-drafted league entirely in your browser. An account is only needed to run or join a multi-owner league.
- What happens if I miss my draft pick?
- Each seat has a pick clock set by the commissioner, from one minute to eight hours. When it expires the computer takes the best available card for that roster slot, so a draft never stalls.
- Can I still make moves during the season?
- Yes. Waivers let you swap cards under the commissioner's waiver rule, and trades between owners require both sides to confirm before rosters change.
