A popular "Chase the Ace" draw will be back in action this weekend, after a duplicate winning ticket mixup prompted organizers to change the way they run the game.

Ahead of the next draw in Sydney, N.S. on Saturday, contest organizers have purchased new tickets, brought in a chartered accountant and invited police to supervise the preparations.

"Each ticket has seven digits, which means there's ten million tickets in each colour," Chase the Ace Sydney organizer Stephen Tobin said. "That in itself is going to reduce the potential for duplicates."

The weekly draw, which is organized by the local Royal Canadian Legion, made headlines earlier this month, when two women both had jackpot prize-winning tickets.

Following the incident, Nova Scotia Alcohol and Gaming stepped in to ensure the mixup wouldn't happen again.

John MacDonald, the Alcohol and Gaming executive director, said the province told organizers they'd need to take extra steps to make sure the draw is fair.

"Those … conditions were that (the organizers) employ a chartered accountant, and that that accountant look at putting in place procedures and policies that would ensure that no duplicate tickets would be there," MacDonald told CTV Atlantic.

But the legion's president is unhappy with the way the situation has been handled, saying the province left it up to the organizers to find solutions.

"They're fishing in the dark too, as to what are the best principles," Legion president John MacInnis said. "I think the rules have to be tightened up and I think they have to apply to all Chase the Ace draws across the province."

The successful contests have attracted crowds and cash in a number of Atlantic communities in recent years.

The draws act as both a fundraiser and a lottery.

Participants buy five-dollar tickets and are entered in a draw. Organizers select one ticket from the pool, and the winner automatically gets 20 per cent of the money that's been raised. Meanwhile, 50 per cent of the money goes to charity, and the remaining 30 per cent is added to the building jackpot.

In addition to winning 20 per cent of the money, the winning-ticket holder is invited to draw a card from a standard 52-card deck. If they draw the ace of spades, they win the jackpot.

The jackpot for the draw in Sydney on Saturday is an estimated $1.3 million.
