Carbon Sports Betting Review & Free Bet Bonus

Carbon Sports was established in 2012 to go alongside their popular sites Carbon Poker and Carbon Casino, which had both been established for years. You can read our Carbon Casino review here.

The company is Australian-based but, due to a merger with Merge Gaming Network, houses its servers in Canada and is regulated by Antigua and Barbuda.

Why should I join Carbon Sports?

Carbon uses a unified account system to provide you access to its online sportsbook, racebook, casino and poker room, all available to US customers and customers worldwide. The entire system is available via the web anywhere that you have Internet access.

Carbon Sports offers an incredible list of awesome promotions for sports bettors, including a 25% deposit bonus for up to a $250 free bet, a free bet of up to $500 on March Madness, a 50% deposit bonus for up to a $100 free bet, and free $25 bets on your first mobile wager AND first mobile horse bet!!!

Carbon Sports Free Bet Bonuses

The Carbon Sports welcome bonus is unique in that is treated just like an online casino bonus. Rather than receive a free small bet as many online sportsbooks offer, Carbon Sports provides a deposit bonus worth up to $250 in free bets. To participate, simply register a new, first account, and then use the promo code CARBON250 during the deposit process.

The sportsbook will then match your deposit by 25 percent up to $250, and that bonus money is available to you right away. In other words, if you open a Carbon Sports account and place a $1,000 deposit, you’ll have $1,250 in your virtual bankroll.

In addition, Carbon Sports provides all players with a mobile free bet worth as much as $25. To take advantage, place a first-time mobile bet of at least $5, and the house will match that amount by 100 percent up to $25.

Note that this additional bonus is stackable with the welcome bonus.

Clients can claim an addition $25 by placing their first mobile horse-racing wager as well.

Carbon Sports Reload Bonuses

Casino Sports also provides clients with a 50-percent match up to $100. To claim it, deposit at least $10 and use the bonus code FREE100. Clients can choose to use this promotion on their second deposit or in lieu of the welcome promotion.

The sportsbook also offers a weekly reload bonus that’s available every Thursday and Friday. The bonus is a 5-percent match, and you can earn as much as $500 in bonus money each week. It’s all right to make multiple deposits over the two-day span, but you can’t earn more than $500 that way in a given week.

Carbon Sports has a seasonal promotional calendar. For instance, during the Sochi Olympics, there were many additional free bets available for those events, and at the time of this writing, Carbon Sports was gearing up for March Madness by offering a $500 free bet contest and a $25,000 bracket contest.

The racebook also offers a daily rebate that’s worth as much as eight percent. It’s a great opportunity for punters who bet the horses, but keep in mind that it doesn’t apply to sports wagers. How it works is that at the beginning of each day, Carbon Sports deposits a rebate into your account. That rebate is worth three percent of losses on straight wagers from the previous day and eight percent of losses on exotic wagers from the previous day.

Most online sportsbooks and racebooks don’t offer any kind of deposit bonuses at all, so the fact that you can claim an additional $500 in bonus money each week is a big deal. Carbon also has a very client-friendly approach to bonuses and banking. Clearing a big bonus or making a large withdrawal isn’t going to be a problem, and the company has an excellent reputation for security and integrity.

How to Use Your Free Bets

Wagering Requirements

The standard wagering requirement at Carbon Sports is a 35-times rollover of all bonus money. Carbon doesn’t ever require you to roll over deposit money. It does require that all bonus money be played through at least once. This is relevant because Carbon doesn’t require any wagering at all on some small bonuses. For instance, the $25 free bets don’t require anything other than being played through at least once. Requirements do tend to vary slightly from one promotion to the next, so be sure to check the details for individual opportunities.

Carbon Sports Review

All Carbon Sports betting services are available from the website, there is no program or software that needs to get installed on your computer. Some portable devices may not be able to handle the technical requirements of the website; in those cases, you can opt for Carbon Sports’ mobile app instead, which supports Android, iPhone and other devices.

The market selection at Carbon Sports is expansive. In addition to sports, it covers horse racing, dog racing and markets for special events, such as politics, American Idol and the Academy Awards. Sports betting includes standard wagering as well as futures wagering and prop betting. The focus at Carbon is FIFA, NBA, NHL, NFL and MLB, but you’ll find nearly every sporting event imaginable, including those specific to small regions in India, Australia and so forth.

The common bet types at Carbon are spread betting, money-line betting and over-under betting. Carbon also offers a sophisticated system for multiple bets, or parlays, and there isn’t much restriction to the various types of bets that you can mix and match. The sportsbook usually has a parlay promotion in place for whatever’s in season that gives you a chance to win double or more or get a rebate if you bust out.
