but they dice is shit. i lose many times on 80% winning chance in a row when i bet big.
on the other hand on bc.game i won tons of times i didnt find anything sketchy with them.
This is just about luck... You should be able to see the provably fair result on each of your rolls on both sites. And both of them have a house edge of 1%. So, both games are alike.
Declaring a game better than another one just because you had better luck on it isn't correct, because some users will have better luck on the other site. A good point of comparative would be the max multi they offer.
Personally I think the best dice game out there is Just-Dice. Even if the site is not for bitcoin they allow you to win x990,000 and that multiplier is just crazy. My biggest win there was an x330,000 and takes me 2 days to hit it.
