London-listed 888 Holdings is now pooling poker liquidity across three US states after New Jersey officially joined Delaware and Nevada in the Multi-State Internet Gaming Agreement (MSIGA).
Players in all three states are now able to compete in cash games and tournaments, though only via 888 and its partners.
As the only company licensed in each territory, 888 is the only provider eligible to operate an intrastate poker network, which allows players of WSOP.com in Nevada, The Delaware Lottery and the New Jersey-based All American Poker Network (AAPN) to compete against one another.
"The launch of the 888-powered interstate poker network is another significant milestone for the US igaming market. Poker players across all three regulated states can compete with each other through the 888 unique, proprietary platform," 888 chief executive Itai Frieberger commented.
"This is great news for customers and our partners and further demonstrates 888's commitment and unique position in the regulated US online iGaming market," he said. "I would like to take this opportunity and thank the Nevada, Delaware and New Jersey regulators for initiating and supporting this effort, and hope to see additional states come aboard our poker network soon."
WSOP.com head of online poker Bill Rini added: "We're thankful for the efforts of all involved that made this milestone possible. We've been with 888 since Day 1 of our U.S. operations and it's a testament to our shared passion for poker that we've been able to reach this momentous achievement together."
The tri-state network was been facilitated by New Jersey joining Delaware and Nevada in signing the MSIGA in October last year. Nevada and Delaware have been sharing poker player liquidity via 888's interstate network since March 2015.
New Jersey Division of Gaming Enforcement director David Rebuck said the state had been happy to see his state join the network.
"We are pleased for the additional opportunities this agreement provides not only for online poker players in Nevada, New Jersey, and Delaware, but also for other states that may want to participate in the future," Rebuck said.
Nevada Gaming Control Board chair Becky Harris echoed Rebuck, describing the addition of New Jersey as creating "a solid framework for expansion".
Delaware State Lottery director Vernon Kirk added: "The Delaware Lottery is very pleased to be able to offer Delaware's online poker players this exciting opportunity to enhance their gaming experience.
"The Multistate Internet Gaming Agreement has proved to be a great vehicle for allowing its member states to take advantage of such cooperative efforts."
