It is impossible to predict which reward you will receive for completing the guest's 4th order - the reward is generated randomly. You can get a ticket or a simple gift, and we cannot influence your luck in any way. Sooner or later, you will definitely be lucky and get more tickets than simple gifts.
You can always get a guaranteed ticket to complete the guest's 5th order.
Suppose you are only interested in getting tickets. In that case, we recommend you to look at other ways to get them - you can buy tickets in the bank for diamonds or in the special offers.
