Greetings all Pet Rescue Saga players, Does anyone have any information on how this works? I'm right now on Part 5 and 60 with the Petopia fruits and vegetable event. I keep seeing these and when I click on them, they say " Win levels to get the dig up treasure cards". I've never been able to open them no matter how much I play. I'm just curious now to how they are opened. Anybody been able to open them, please respond? Thanks
