How It Works
Windfall makes sports prediction social, competitive, and completely free.
Create or Join a League
Start your own private league or jump into a public one. Invite friends, set the rules, and pick which sports to include.
Make Your Picks
Browse upcoming games, check the odds, and make your picks. Moneyline, spread, over/under, same bet types, zero real money.
Climb the Leaderboard
Track your win percentage, ride hot streaks, and prove you know ball. Top your league and earn bragging rights all season long.
Track Your Edge
Anyone can pick winners on a hot streak. The real question is whether you're actually good, and Windfall's analytics answer it. Go past win/loss and see the numbers sharp bettors live by.
Closing line value
The single best measure of picking skill: how often you beat the closing line, proof your reads are ahead of the market.
Performance breakdowns
Win rate and ROI sliced by sport, bet type, and favorites vs. underdogs. Find your strengths and your leaks.
Skill vs. luck
Compare your results to what the odds expected, so you know whether you're genuinely sharp or just running hot.
