This is a Golden Ticket competition. You can get these for items from the list you are able to find, but only if there is a phenomenon in the room. Tickets will drop in different quantities, and not from every item you find. You have different chances of gaining items in different rooms.

By unlocking rooms at a higher level, you can get more tickets for items on the search list. In addition, the higher your skill level in the room, the more items will be on your search list, and, accordingly, the more Golden Tickets you’ll be able to get. The number of Tickets received also depends on the mode in the room during your exploration.

Try to collect as many Golden Tickets as possible: they will give you a high place in the leaderboard and the opportunity to get a luxurious prize!
