Questions
Good to know.
Do I have to bet to use GammaLine?
No. Forecasts and lessons work without a sportsbook. If you do bet, you do it at your sportsbook, never here.
Is GammaLine a sportsbook?
No. GammaLine never accepts or places bets. You can open your picks at FanDuel and place them there yourself, or just save them.
Will GammaLine tell me which picks will win?
No one can promise that. We give a forecast, show how it was reached, name the biggest uncertainty, and publish how we did.
Which sports and picks are covered?
NFL (catches, receiving, rushing and passing yards, touchdowns and attempts), MLB (hits, total bases, home runs, runs, runs batted in, the three combined, and pitcher strikeouts) and WNBA (points, rebounds, assists, threes and the combinations).
Where do the numbers come from?
Stats come from the MLB Stats API, ESPN and nflverse. Prices come from FanDuel’s public feed. The forecasts are GammaLine’s own models, explained on the How it works page.
How much does it cost?
Lessons are free, with no account needed. Live forecasts are $9.99 a month or $99.99 a year for everything, across all three sports. New web accounts get a 7-day free trial: you add a card, and you are not charged until the trial ends. It renews automatically and you can cancel anytime. See pricing.
Is there an iPhone app?
Yes, it’s on the way to the App Store. Your GammaLine account will work on both the web and iPhone.
Who can use GammaLine?
Adults 21 and over. If you choose to bet, only do it where it’s legal for you, and never with more than you can afford to lose.
