Visibility for screen

I am making a tournament style app. In the App Every user will predict the match, and if the user didn’t predict the match well then they are out of the tournament. The problem I am confronting is, suppose, Winners from round 1 cannot move on to 2nd round if their prediction goes wrong. I want to set a visibility where losers from round 1 are unable to see screen of round 2 or Vice Versa.

How are you presenting the “screens” to the users? Are they different tabs or different items on the same collection/inline list?

For admin I have separate tabs where he makes the matches. So for users I have also created different tabs and The items are different also. The inline list in users screen is taken by admin tabs however User can’t click the inline list it is just for display.
