Ultimate Bet

Cereus Poker Network was an online poker network comprising Absolute Poker and Ultimate Bet. The site is now insolvent and not processing player withdrawals. Cereus is owned by a private company, Blanca Games. Blanca Games bought all Network assets in August 2010 from Tokwiro Enterprises. The Cereus network was one of the world's ten largest online poker cardrooms prior to losing the majority of its player base in the wake of the April 15, 2011 online poker indictments.

Absolute Poker was established in 2003. It was licensed by the Kahnawake Gaming Commission.

In September 2007, Absolute Poker began defending itself following accusations made by members of several Internet forums that the online poker room has a "superuser" account which allows one player to read the hole cards of another during a game. By October, widespread Internet allegations of cheating led to the Kahnawake Gaming Commission beginning an investigation.

Although allegations had been made about several accounts, one of the most remarkable pieces of evidence was a complete history of a tournament which was won by a player called "POTRIPPER". This history was far more complete than normal; it included all hidden hole cards for all of the players at the table, and the IP addresses of players and third-party observers who were watching the game via the internet. It was sent out, perhaps by accident, when a player complained about suspicious play. Reviewing the data, mathematician and gaming expert Michael Shackleford said:

Hand after hand POTRIPPER’s play is consistent with that of a player who had knowledge of every player’s hole cards. The majority of hands show POTRIPPER bluffing at just the right times when his opponents were weak. Yet, when he was hopelessly outmatched, even with good cards, he laid them down.

Shackleford subsequently blacklisted Absolute Poker on his gaming related website.

On October 19, an unofficial source within Absolute Poker claimed that an employee had hacked the system to "prove a point". On October 21, Absolute released an official statement:

...it appears that the integrity of our poker system was compromised by a high-ranking trusted consultant employed by AP whose position gave him extraordinary access to certain security systems. As has been speculated in several online forums, this consultant devised a sophisticated scheme to manipulate internal systems to access third-party computers and accounts to view hole cards of other customers during play without their knowledge. [...] We will pay for all losses suffered by the affected players as soon as our audit is finished and the amounts are determined.
