According to the BBC, Grand Lotto participants have to select six numbers from one to 55. The strange and unusual result of Saturday's Grand Lotto warranted an investigation, according to the Philippines senate minority leader Koko Pimentel.
He said that they will file a resolution because this is my concern. These lotto games are authorised by the Republic of the Philippines. We need to protect the integrity of these gambling games that we have authorized. Pinmentel said he would seek the opinion of statisticians and mathematicians regarding the results of the PCSO draws.
Senator Risa Hontiveros said in a statement that she supports an investigation to rule out any perceptions that the jackpot results had been manipulated. She also wants to make sure the system is secure, free from glitches and trustworthy.
The PCSO, which is government-owned, pointed out in a local news conference that Filipinos tend to bet on number sequences. General Manager Melquiades Robles said in a Facebook post on Sunday that lottery is a game of chance and that it is uncontrollable and it pays to be loyal to the 433 new jackpot winners. He added.
