You can subscribe at the time you place the bet by marking the option ‘Subscribe to this play’ or after the ticket is generated, select it in the ‘My Tickets’ section. Click on the ticket or the ‘+’ icon and tap on the gray heart. It will ask you to confirm the subscription, and you will be subscribed to the draw. The ticket will be repeated with the same characteristics for the next draw.
If you want to unsubscribe, you will see that the heart appears in green color on a ticket with a subscription. Tap on it, and it will ask if you are sure you want to unsubscribe. Confirm, and the green color will disappear, indicating that you have unsubscribed.
