PartyGaming revealed a 21 percent increase in revenue in the first quarter of 2008 to $128.9 million from $106.2 million a year ago.
The company's shares, however, shed 5 percent Wednesday as analysts projected lackluster full-year growth in light of its disappointing start to the second quarter. In the first four weeks of April, total average daily revenue was down 1 percent with poker slightly weaker than expected.
