How would i make a part that would teleport them to every round (60 secs)?

To teleport someone, you change the CFrame of their Torso or use the MoveTo() method on the character model itself. I'll use MoveTo().

To get ALL the players, loop through them with a for loop.

To do this forever, use a while loop.

while true do
	wait(60)
	for i,v in pairs(game.Players:GetPlayers()) do
		v.Character:MoveTo(game.Workspace.Part.Position)
	end
end
