A similarly uncommon spike of winners was observed in the United Kingdom in 2018, when five from the six quantities were being multiples of 7. In 2020, a streak of consecutive quantities (5, 6, seven, eight, 9, ten) manufactured multiple jackpot winners in South Africa.
Also, You need to understand that the winning sequence will be the Philippines lotto is not any more unlikely to be drawn than another sequence of figures. The probability of 9, eighteen, 27, 36, forty five and 54 remaining drawn are exactly the same as, say, one, eighteen, 19, 28, 30 and 46.
