A wide variety of NCAA contests and sports betting bonuses are available online

For the vast majority of us that cannot get out to the desert or that have sports betting in our backyard, the online gambling community pulls out all of the stops for the NCAA Men's Basketball Tournament. It is the single biggest betting event of the year. It is not the biggest day, that would obviously be the Super Bowl, but the biggest single event with over 36 games just this week and a myriad of daily and future props to bet on. You can find both huge bonuses and giant contests online.

If you are looking for a cash bonus, BetMania offers their MarchMania bonus, a 100% Cash Bonus on just a $300 deposit. GTBets offers up 150% cash split between the first two deposits - 100% up to $500 on an initial deposit and 50% on the second one. SkyBook is taking care of OSGA friends, fans and members with a special 100% cash, Low Rollover bonus, where players also get a free entry into their bracket contest (use code OSGA). BetNOW continues to offer a 50% cash bonus, also with a low rollover, every day. WagerWeb offers three different levels of bonus, where players can choose cash or free play, the amount of bonus and the amount of rollover. For players using Bitcoin, BookMaker offers a 25% cash bonus every time a player deposits with the cryptocurrency and BetOnline gives a first time Crypto Bonus of 100% using Bitcoin, Bitcoin Cash, Ethereum, DASH or Litecoin.

Bracket contests are abundant, with some online sportsbooks offering a million bucks or more for a perfect bracket.



The largest prize of all is 5 million dollars, offered via the Heritage March Millions contest only at Heritage Sports. Players can win a million bucks at BookMaker, WagerWeb and Diamond Sports, but all of these contests have prizes in the likelihood that no one hits a perfect bracket. Heritage is giving 500 players prizes with the top one being 10K. BookMaker is giving away huge amounts of BetPoints, plus $10,000, WagerWeb will give out 100 prizes to the top scorers with a 5K top prize and BetDSI will payout out the top three players with cash and every one who enters will get BetPoints, with places 4-100 getting 15 thousand of them.

For contests that don't include a million dollar, perfect bracket prize, MyBookie has upped their annual offering to a 75K prize with a $15 entry fee and a $7,500 top prize and the top 125 places getting paid. BetOnline has a 50K prize pool with a $10,000 first place prize for a $15 entry fee and will have a Sweet 16 contest available with reduced entry fees. BookMaker will give players another opportunity in their Second Chance Bracket Contest with a $20 entry fee and prize ranging from $5,000 to 500 BetPoints. Skybook has a contest pool that starts at $10,000 and increases with the amount of entries - up to 3 times!

Finally, 5Dimes is doing something a bit unique. There are individual, unique contests for each of the first three NCAA Tournament rounds. The Round of 64, like other contests, start on Thursday, but on Saturday the Second Round, Round of 32 contest will be available. The 5D contest offerings end with a Sweet 16 contest. For each round players choose the value for their bracket ($1, $5, $10 or $25). The contest is really an App that works great on mobile devices.

Here at OSGA we are having our 18th Annual NCAA Tourney Contest. The contest is better than ever with all new software that is mobile-ready and a $1000 Prize Pool up for grabs. Players in spots 1-5 will receive cash and this is the second year where OSGA Members get rewarded for their loyalty with Double Prizes.
