This Saturday's $1.3 million Chase the Ace draw in Sydney has been postponed partly because of concerns surrounding the security and integrity of the game.

Last weekend’s draw produced two tickets and two winners with the same number. The Nova Scotia Alcohol and Gaming Commission has said they would put this weekend's draw off if they weren't confident the problem would be fixed in time.      

Organizers are also citing traffic concerns with the Vince Ryan Hockey Tournament taking place on the same weekend.        

The draw is expected to resume on Saturday, March 26.
