To get teleported to an other place you have to wait until 10 or more players join the game... if the 10 players join the game... add a 2 minutes waiting until get into the other place ( where the game is at ) so on those 2 minutes more players can join.
Script:
local TeleportService = game:GetService("TeleportService")
local level1Id = 1839211325 -- starting place
local level2Id = 1939050771 -- game
if < 10 and > 100 #_G.gameplayers
script:WaitForChild(120secsuntilbegin).Visible = true -- frame that says 120 second until the game begins
wait(120) then
script:WaitForChild(120secsintilbegin).Visible = false
local player = game.Players
if player then
TeleportService:teleport(player, level2 )
end)
end
