🕸️ Cereus Network (Absolute Poker + UltimateBet) – Historical Review
The Cereus Network was formed in 2007 from the merger of two scandal-plagued poker rooms: Absolute Poker and UltimateBet. Despite both sites having been caught allowing insider cheating through superuser accounts, the Cereus Network continued operating for several more years before being shut down on Black Friday. The network represents perhaps the most cautionary tale in online poker history — a case study in how lack of regulation enabled repeated fraud against players.

📖 History & Rise
Absolute Poker and UltimateBet merged their player pools in late 2007 to create the Cereus Network. Both sites had already been implicated in cheating scandals by this point, but continued operating due to the lack of regulatory oversight in their Costa Rica-based operations. The merged network initially saw reasonable traffic as players in unregulated markets had limited alternatives.
⚡ What Made It Special
The Cereus Network’s only “special” characteristic was its notoriety. Both sites continued offering standard poker products — Hold’em, Omaha, tournaments, and cash games — but operated under a permanent cloud of suspicion following the superuser scandals. Some players remained loyal due to limited alternatives in the US-facing market.
💥 The Downfall
The Cereus Network was included in the Black Friday indictments on April 15, 2011, when the US Department of Justice seized the domains of the three largest US-facing poker sites: PokerStars, Full Tilt Poker, and the Cereus Network (Absolute Poker + UltimateBet). Unlike PokerStars, which eventually repaid all US players, and Full Tilt, which was rescued by PokerStars’ acquisition, Cereus Network players largely never received their funds back. The network was simply shut down with no resolution for player balances.
🏛️ Legacy & Impact
The Cereus Network stands as the worst-case scenario for online poker — operators that cheated their own players, continued operating without accountability, and ultimately collapsed leaving players with nothing. Its history is frequently cited by gambling regulators worldwide as justification for strict licensing requirements, independent auditing, and segregated player funds. Every modern regulated poker market has implemented safeguards specifically designed to prevent a Cereus-type situation from ever happening again.
Frequently Asked Questions
- What was the Cereus Network?

- Why is the Cereus Network significant in poker history?
- The Cereus Network represents one of the darkest chapters in online poker.
