Call it a personal bias, but I have tried a number of dice sites but I always found myself coming back to the one that set the bar for every other dice site that came after. And of course that one was Just-Dice! Things have changed a bit, more backend features and now it uses the coin CLAM; but if people ever wanted to play OTC trades in and out of CLAM from BTC are offered using the built in /escrow feature to protect those that do not want to "invest" in the coin and just want to play for 'ol time sake :-)
J-D rocks my socks!
