One lucky local Lotto player is more than half a million dollars richer, after a winning ticket was sold at The Lucky Charm in Secret Harbour.
The ticket matched the winning numbers of 11, 29, 23, 8, 16 and 15 in Saturday's Division One prize on the weekend.
The lucky winner, who is yet to claim their cash, will take home more than $642,600.
Lotto luck struck four times throughout the state on Saturday, with other winning tickets sold at Armadale Newsagency, the Good Lucky Lottery Centre in Hillarys and online.
The weekend prizes bring the tally of Division One winners this year to 16, 13 of those from Saturday Lotto.
Players will next have the chance to win big in tonight's Monday Lotto and Wednesday night's Cashcade promotion.
If no one wins the Monday or Wednesday Lotto Division One prize, Divisions Two-Six will share in $1 million.
