I've visited many many gambling websites throughout my life. I played Dice on a lot of websites but this has never come to me at SafeDice.com. I will visit this site right now and if I really like it then add it to my list of favorite gambling websites.
The best tip on finding good gambling sites are reviews here in bitcointalk. There are too many web sites that are good looking but what are important things to ponder are the fairness and its support.
Try to read above the comments. Especially the original post too where the poster is already red tagged.
