Coinroll

Coinroll (coinroll.com)

Coinroll (also described in some sources as “Coinroll Bitcoin Casino”) is an online gambling/entertainment service associated with Bitcoin-based casino gaming, best known for offering an instant-play “dice” game in which wagers and outcomes are designed to be cryptographically verifiable (“provably fair”). (csidb.net)

Service description

Contemporary third-party descriptions characterize Coinroll as a minimalist Bitcoin dice site that historically emphasized:

• No-registration / instant play (deposit and begin betting immediately)
• Very small minimum bets
• “Off-the-chain” instant bets and provably fair verification claims (newcasinoreviews.com)

Security incident (2016)

Coinroll is notably referenced in connection with a 2016 security incident involving an exposed MongoDB database. Reporting from April 2016 describes a leak of user-related data (including hashed passwords) and subsequent user reports of stolen balances, with Coinroll stating it was conducting an audit and temporarily disabling withdrawals/deposits during investigation.

Potential name confusion (other “Coinroll” entities)

The name “Coinroll” is also used by unrelated services, including:

• coinroll.app: a separate fintech/infrastructure venture described as building regulation-oriented digital finance infrastructure. (coinroll.app)
• coinroll.bet: a different domain that multiple security/reputation sites have described as high-risk/suspicious (not the same as coinroll.com). (gridinsoft.com)
