the script:

local maps = game.ServerStorage:WaitForChild("Minigames")

local InMatchColor = "Really red"
local InLobbyColor = "White"
local map = {}
math.randomseed(tick())
local Sync = game.ReplicatedStorage:WaitForChild("Sync")
local Sync2 = game.ReplicatedStorage:WaitForChild("Sync2")
script:WaitForChild("Config")
