And it is possible crypto-games is not open with their stats so it cannot be added.
Wrong, and easily to check for you. Crypto-Games offers public investments and hence provides all necessary stats, more than some casinos listed.
Further, all stats are available via API (
https://api.crypto-games.net/v1/coinstats/BTC and
https://api.crypto-games.net/v1/settings/BTC for BTC).
crypto-games is a casino not just a traditional dice site either so it isn't as easily comparable.
Yes and no. It's possible to just list the dice part of the casino, the stats for the dice game are available seperately and can be compared to the dice stats on all other sites.
Bitdice offers more games than just dice aswell, so does nitrogen (sports). Those sites are listed.
Yeah I checked out crypto-games and you could make a case that it should be added. But I am not sure what other sites gamblingbad is talking about.
