Superbook
Superbook, which was launched in 1995 and currently owned by Sportingbet PLC, was named “Best US Sports Book” in 2005 and 2006, by leading magazine eGaming Review. However, it was not long after that the site developed a bad reputation: when it moved operations to Costa Rica, players in the US had their pending wagers withdrawn and were denied access to their accounts.
Of course, this was a serious black mark against the site, but Superbook has cleaned up its act recently, and if you are looking for good bonuses, they offer some of the best in the business.
Instant Cash Signup Bonus
This promotion promises much for newcomers, offering a bonus of up to 15% on first deposits, up to the value of $500. In order to take full advantage, you will need to make a deposit of $500 or more – smaller amounts will receive only a 10% bonus.
The minimum deposit for this promotion is $20, while the maximum is $1000. Superbook states that all bonuses will only be rewarded when the deposit and bonus amounts are wagered twice in the sportsbook, e.g. for a deposit of $250 with a $25 bonus, a player’s wagers must reach $550 before the bonus can be withdrawn.
5% Reload Bonus
This is an attractive offer on Superbook and is available for both new and existing members. The Reload follows the same conditions that apply to the Instant Cash Bonus, while the minimum deposit – and maximum value – is $250. Although the site has a limited daily deposit of $1000, it is possible to pay more into your account using a credit card.
Refer a Friend Bonus
Superbook’s Refer a Friend Bonus offers both customers a 20% cash bonus, up to the value of $200. In order to be eligible for the promotion, the new player must make a deposit of $50 and have used 50% of their funds before making a withdrawal, in addition to meeting the terms and conditions of the signup bonus.
Should your friend fail to use 50% of their deposit in seven days, the 20% bonus will not be automatically credited to your account, so you will then have request the bonus once they reach this figure (for which you will have a 60-day timeframe). However, they will still receive their share of the bonus. Of course, there is no limit to the amount of friends you can bring to Superbook, but it will be strictly one bonus per new customer.
Other Promos
In addition to these bonuses, Superbook provides a series of other attractive promotions on their sportsbook. In the ‘Race of the Week’, you can double your winnings when you place a wager on a horse with odds of 2/1 or higher.
For their mobile service program a free $20 bet is offered once you download their software to your handset (for any NBA or NCAA Basketball Half-Time Line). However, this promotion is only available on a lost wager.
