I tried a new website.And noticed its lottery game is strange.
You can bet on odd/even or other number combinations.see here

What's abnormal is that I found it turned out to be even for 8 times continuously!It's possibility is low to 1/256!
I think they are cheating,don't play their game!
I saved the screenshot here:http://p1.bpimg.com/1949/e40b30927d453419s.png
