BOSTON  -- Massachusetts has put a limit on ticket purchases for a certain lottery game following a report that sophisticated gamblers were buying hundreds of thousands of dollars' worth of tickets, guaranteeing them a profit due to a loophole.

Treasurer Steven Grossman said Monday stores can sell a maximum of $5,000 worth of Cash WinFall tickets in a single day.

He also said the game, which has seen declining sales since it was introduced in 2004, will be phased out next spring.

Grossman acted following a report in The Boston Sunday Globe that said professional gamblers found a quirk in Cash WinFall's rules that virtually guaranteed them a profit if they bought over $100,000 worth of tickets at certain times of the year.
