About this app
NFL. MLB. NBA. NHL. Tennis. Soccer. Make the call on all of it. Onyx is a free-to-play social sportsbook. Live odds on every game, same-game parlays, in-play picks all game long, and a slip that tracks itself. Free to play in 35+ states. ▸ TODAY'S BOARD Spread, total and moneyline on every game, plus player props — anytime touchdown, rushing yards, receiving yards and more. Odds shift as the game approaches, and you choose whether your slip follows them or keeps the price you picked. ▸ BUILD THE PARLAY Stack legs across the whole slate, or build a same-game parlay out of a single matchup. The more legs you add, the longer the odds, so a parlay that lands is worth far more than those picks separately. Or skip the build entirely and take a Featured Parlay, put together for you at long odds. ▸ TAKE THE BOOST Boosted parlays go up on the headline games every week.…

Themes reported by reviewers
No theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
90% or more five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.
