Zoom Poker, the 'fast fold' poker launch from PokerStars, was blamed for the continuing poor performance in poker from online gaming giant bwin.party.
In a trading update the firm said solid performances in casino and bingo was offset by its poker performance, along with disappointing sports betting results.
'In poker, as for many other operators, the competitive challenges experienced in April continued in May and June, exacerbated by the Euro 2012 Championship and the launch of Zoom Poker on PokerStars that went live at the beginning of the second quarter,' the statement said.
Bwin.party said it hoped to launch its own 'fast fold' poker solution in the second half of 2012, when it will also complete its long-awaited integration of its bwin and PartyPoker brands.
The firm also added it was pushing ahead with the sale of its Ongame subsidiary, despite the withdrawl of US-firm Shuffle Master from its proposed €19.5 million takeover deal.
'Following the withdrawal of ShuffleMaster from the purchase of Ongame, six potential purchasers have expressed an interest in acquiring Ongame,' bwin.party said.
