Software graphics: 91%
Rival software plus an excellent landing page get the new-look Black Diamond Casino top marks in this category.
Game variety: 81%
The games are good, but Rival could make do with more video poker and especially progressive jackpot slot options.
Sign up bonus: 93%
A $25 no-deposit bonus plus the option to take up to $1000 on first four deposits with bonuses of 50% to 200% per make for good reasons to keep playing at Black Diamond.
Promotions: 60%
The opening bonus is great, refer-a-friend bonuses are $50 each and the comp points are generous but ... no tournaments on offer? Not positive.
Wagering requirements: 70%
It depends on where you are: Deposit bonuses carry 25x bonus playthrough, but 30x for euros and 40x for pounds sterling.
Progressives: 72%
Black Diamond does stock four good progressive games, including Major Moolah and 1,000,000 Reels BC, but that's it, really.
Banking options: 85%
Black Diamond Casino accepts Visa, American Express, UseMyWallet, Click2Pay, eWalletXpress, EcoCard, Moneybookers, ClickandBuy, UseMyBank, and Neteller -- and nearly all of these can be used for withdrawal as well.
Customer support: 87%
Customer support is well-covered at Black Diamond, with chat, phone, fax and email support provided around the clock.
Payout percentage: 35%
The payout percentage at Black Diamond was once quoted at 97.8%, but that was a long time ago. These days, there's no indication of that number or independent audits on the site at all.
