LeagueLines

LeagueLines connects to your real Sleeper or Yahoo fantasy football league and turns your roster strength into real, Vegas-style odds — championship odds, playoff odds, and weekly matchup predictions, all built from your league's actual scoring rules and real player projections.

FREE:
- Connect as many leagues as you want
- Get preseason championship & playoff odds for each one

UPGRADE A LEAGUE ($5.99 for 3 leagues, $0.99 per additional league):
- Odds update automatically as the season plays out — catching trades, injuries, and real wins and losses
- Weekly matchup odds: spread, moneyline, and win probability for every real matchup in your league
- Share a clean, sportsbook-style odds graphic with your league mates

Built for real leagues, not simulations — LeagueLines reads your actual roster, your actual league's scoring settings, and your actual schedule to generate odds that mean something to your specific league.

Odds are model-generated estimates based on historical performance and league scoring rules — not a guarantee of outcomes, and not a real-money betting product.
