isal has seen a boom in its SuperEnalotto game as the top prize has climbed to more than 100 million euros, with analysts even suggesting that the success could result in more players switching from rival Lottomatica's Lotto game.
Last night's jackpot for the SuperEnalotto game stood at a record 107 million euros, breaking the previous record of 100.7 million euros, which was won last October.
In a statement yesterday, Italy's antitrust authority said that Sisal was suspected of stopping competitors from getting online to seek clients among SuperEnalotto players.
Sisal has responded by saying that the online inflow of bets for the game was being organised according to its concession and in accordance with procedures set out by Italy's regulatory authority, Amministrazione Autonoma dei Monopoli di Stato (AAMS).
Sisal added that it would give the antitrust authority all of the documents and information it has requested. The company confirmed earlier this month that it had been awarded an exclusive license to operate national pari-mutuel numbers games in Italy for the next nine years following a competitive tender, continuing the company's involvement with the popular SuperEnalotto game which it launched in 1997.
Last year Sisal saw gross gaming revenues from its SuperEnalotto game reach 2.5 billion euros, with 15 million players taking part, a 29% increase over the previous year.
