MANILA - Even foreign bettors can win the estimated P1.07 billion jackpot of Ultra Lotto 6/58, the Philippine Charity Sweepstakes Office (PCSO) said Thursday.

"Yes, they can play the lotto and they can win also. RA 1169 (PCSO Charter) does not state any prohibition on foreigners to play lotto," PCSO told ABS-CBN News.

All lotto players must be 18 years old and above to buy tickets and claim winnings, according to the PCSO website.

The Ultra Lotto 6/58 jackpot is estimated at P1,070,000,000 as of 4 p.m. Thursday. It is the highest lotto prize in history. In 2010, a lone winner bagged the P741 million Grand Lotto 6/55.

The prize money, however, can change depending on the "total sales generated and the number of winners on the particular draw."
