How do you teleport all players to another game?

use this script

local id = 123456789 -- replace 123456789 with the id of your place you want the players to teleport to
local ts = game:GetService("TeleportService")
-- maybe you could add a function here but this script will just tp all the players right away i think you should add like a while true loop this is what i will do
while wait(25) do
local players = game.Players:GetPlayers() -- create the table
for i, v in pairs(players) do -- do a function for each part of the table

ts:Teleport(id, v)

end

this should teleport all players to the other game every 25 seconds!
