Hello Zahar,
In the New Experience, you'll have to enable the Attendee Hub/Event App as a feature first, under General > Event Feature, before the Attendee Hub menu shows up in your left-hand column. Once that pops up, got to Attendee Hub > Website and App > Manage Website and App. Once you're in that builder, the game is under Features.
Best,
