Best Sweepstakes Sportsbooks for 2026 NBA Preseason

There's an old saying: "don't put all your eggs in one basket." Another saying goes: "never find yourself in a room with one door."

The point is: have options.

The best option for NBA fans and bettors is to use the time between now and opening day of the season to find the best sports wagering platforms for your needs. And, not all of them are created equal.

We select the three best sweepstakes sportsbooks for NBA Preseason, which begins Saturday, and give a short overview on what the 2026-2027 NBA season might bring to us.

What to Expect in the Upcoming NBA Season

For the first time in more than five decades, the New York Knicks will be the hunted instead of the hunter. And every other team has a hunting license. It says here the Knicks won't be repeat champs. But there will be plenty of great storylines in 2026-27:

• Following a taste of the NBA Finals before many experts thought, Victor Wembanyama will be motivated to get his Spurs a championship.
• The Oklahoma City Thunder are still lurking as an NBA behemoth, with many of the best young stars in the league.
• LeBron James is still playing, thank you very much. This time he's in Philadelphia where he hopes to bring a Knicks-style, curse-ending season to Sixers Nation.
• Stephen Curry & the Warriors are not dead yet. The Golden Boys may be Grey Gold, but the veteran Dubs still have magical shooters to compete.
• Anthony Edwards gives the Western Conference another dangerous team. The Minnesota Timberwolves still seem to have their window open for a first-ever Finals run.
• The Toronto Raptors are hoping time travel really works: the team has acquired Kawhi Leonard in hopes of rebooting the title run it had in 2019.
• For the first time since the 2017 season, the Los Angeles Lakers will start the season without LeBron in purple and gold. The focus shifts to lean-for-now Luka Dončić as the rudder of S.S. Showtime.

Ranking the NBA Apps for 2026-27

These ratings for social sweepstakes are the result of hands-on use by an NBA betting fan.

Fliff

APP RATING: 4.8 Stars on Apple Store / 4.7 Stars on Google Play

What can you expect from Fliff? Bettors can target core markets — including moneylines, spreads, and totals alongside deep menus for NBA player props, alternate lines, and quarter or half splits. We especially like alternate lines for finding betting opportunities on games where we expect a more dramatic result.

Standard spreads from Fliff Social Sweepstakes book typically feature familiar -110 juice, aligning this platform closely with conventional commercial betting apps.

We don't always play parlays, for obvious reasons (I like to keep my purse close), but if we do there's no better social sportsbook than Fliff. In most cases, the parlays have the bets odds for NBA players, even compared to real-money sportsbooks like FanDuel and BetMGM.

We often use Fliff to test parlay betting strategies before deploying them onto other apps where we also spend some of our monthly NBA betting budget.

Onyx

APP RATING: 4.8 Stars on Apple Store / 4.5 Stars on Google Play

Onyx Odds makes NBA betting feel like an arcade with mystical digital sweepstakes tokens. Instead of wire transfers and immediate regret, we juggled Onyx Coins for bragging rights and promotional Onyx Cash to chase real-world prize redemptions. You like redeeming, don't you?

The Fliff app rolls out a full hardwood spread for hoops fans. The standard markets are here, but the fun attraction is the buffet of micro-markets and custom player props. Wager on how many 3-pointers the 20-minutes per game situational rotation guard will make.

With Onyx, it's easy to back an unheralded center to grab eight rebounds or construct an audacious six-leg same-game parlay that assumes a backup guard suddenly turns into prime Steph Curry.

As the NBA season approaches, you'll be able to find bonus offers from Fliff (we got 150 coins for the MLB Postseason, for example). Be sure to use those coins to try out the app and get used to the way Fliff serves up markets and odds. Opening day for the NBA is October 20.

Thrillz

APP RATING: 4.7 Stars on Apple Store / 4.5 Stars on Google Play

Fresh off the WNBA season, where we used Thrillz as a tune-up for the NBA, we've found much to be happy about. A fun feature is the trending bet tab which allows you to see which wagers are getting the most action for a selected game. Fade those odds or flow with the current and grab a bet you may not have had on your radar.

Thrillz is the only social sportsbook with a management feature to allow users to restrict how much they play. In both the free-to-play mode or the mode with real-money cash prizes, tell Thrillz how much you want to put on the line.
