Without Tickets, you won’t be able to play the Gauntlet. But don’t worry, on top of the 3 Tickets you will receive at the start of the event, all players will be able to collect a free ticket every two hours. However, the ticket timer will only show the most significant figure (hours than minutes than seconds), so it can appear that there is only an hour countdown left when in reality this will start at 1:59.
You will also have the option of exchanging tickets for Gems, to do this simply tap on the + symbol next to your Ticket count on the top left-hand side of the Event window.
