How it works
Turning fantasy league matchups into a weekly competition. Every manager starts with 200 Season Pips.
1
Connect your Sleeper league
Enter your Sleeper username and pick a league. The connection is read-only — LeaguedIn never moves or changes anything in your league.
2
Unlock markets
Once lineups are set, your league gets weekly matchup markets and season futures like Champion and Top 3.
3
Predict and climb
Call Yes/No on every market and climb the league board. Your starting balance never counts as profit.
All player, roster, matchup and result data comes exclusively from the Sleeper public API. Season Pips are an in-app currency with no cash value.
