Quick rundown before your first slate. This won't pop up again — tap the "?" up top anytime you want it back.
1
Paste your the-odds-api.com key, pick NCAAF or NCAAB, and hit Load games. The key only ever goes to the-odds-api — nothing else sees it.
2
Basic vs. Advanced (top right of Live lines): Basic shows just FanDuel, DraftKings, BetMGM, Caesars and Fanatics. Flip to Advanced to see every book in the feed.
3
Star the games you care about from the "All games" tab. Starred games — plus any Top 25 matchups — show up under "Featured."
4
Tap "🔕 Watch" on a game to get notified when its spread moves 0.5+ points. On iPhone, add this page to your Home Screen first (Share → Add to Home Screen) — regular Safari tabs can't receive notifications.
5
Optional — sync stars with friends. Click "Create new" to get a shared list ID, send that ID to whoever else is watching, and everyone who pastes it in sees the same starred games.
6
Build a parlay on the right. Enter each leg's current odds, then drag the slider to see how nudging that line changes your payout and your real hit probability. It's a simplified model, not a sportsbook guarantee.

About these numbers
Implied probability is calculated from the individual sportsbook odds for each leg, then multiplied together to estimate the parlay's implied probability. This assumes the legs are independent — same-game legs may actually be correlated.
Percentage points vs. percentage increase are different things. Going from 10% to 15% is a +5 percentage-point increase, but a +50% relative increase.

On iPhone? Tap the Share icon in Safari, then "Add to Home Screen." Notifications for watched games only work once this is added there — a regular Safari tab can't receive them.
