Question: How do I host games – Kahoot! Play & Create Quizzes Review

I would like to challenge my friends but I have no idea how to host games from my phone. When I tap a game it says Play with Kahoot crew or challenge your friends. I tap challenge your friends and it asks me to log in or sign up. I log in and I press play and it goes to play with staff not challenge your friends. Please tell me how. I love your app and want to explore more. Thank you!
