Generating Random Teams While Rotating Players In

Hi All, I ran into a wall and hope someone can help.

I currently have a clunky spreadsheet that will randomly distribute 16 people into 4 teams of 4 for our volleyball games. What I actually need to do is for the spreadsheet to distribute 20 people into 4 teams of 4, and hold the 4 remaining people aside so they can part of the next randomized 4 teams of 4. Rinse and repeat. In the end, everyone needs to play 8 games. And one more complication; the girls need to be evenly distributed amongst the teams.

Any help would be greatly appreciated as I don't even know how to approach this. Thank you much!

Assuming that you have your names in Column A, and that A1 is a header row, the following code should do what you are looking for.

Code:
Sub createTeams()
Dim AL As Object:           Set AL = CreateObject("System.Collections.ArrayList")
Dim r As Range:             Set r = Range("A2:A" & Range("A" & Rows.Count).End(xlUp).Row)
Dim AR() As Variant:        AR = r.Value
Dim TeamSize As Integer:    TeamSize = 4
Dim NumTeams As Integer:    NumTeams = UBound(AR) / TeamSize
Dim Result() As Variant:    ReDim Result(1 To TeamSize + 1, 1 To NumTeams)
Dim IDX As Integer


For i = 1 To UBound(AR)
    AL.Add AR(i, 1)
Next i


For j = 1 To NumTeams
    If j < NumTeams Then
        Result(j, 1) = "Team " & j
    Else
        Result(j, 1) = "Alternates"
    End If
    
    For k = 1 To TeamSize
        IDX = Int((AL.Count) * Rnd())
        Result(j, k + 1) = AL(IDX)
        AL.removeat IDX
    Next k
Next j


Range("B1").Resize(UBound(Result, 1), UBound(Result, 2)).Value = Application.Transpose(Result)


End Sub

This works so much better than what I'm currently using. I'll do the other parts manually. Thanks so much Irobb314!
