Data Store with a Boolean value ?

I want to make a value bool inside the player and then check if it is true or false to check if he has already played the game, if he has already played he will be teleported to the second part of the game but I am having problems, can anyone help me?

I've tried it a few times...

But none of them worked

The Scripts I've tried:

local DSService = game:GetService('DataStoreService'):GetDataStore('JaJoguei')
game.Players.PlayerAdded:connect(function(plr)
    -- Define variables
    local uniquekey = 'id-'..plr.userId
    local savevalue =  Instance.new('IntValue', plr)
    savevalue.Name = 'JaJoguei'

    -- GetAsync
    local GetSaved = DSService:GetAsync(uniquekey)
    if GetSaved then
        savevalue.Value = GetSaved
    else
        local NumbersForSaving = {savevalue.Value}
        DSService:SetAsync(uniquekey, NumbersForSaving)
    end
end)

game.Players.PlayerRemoving:connect(function(plr)
local uniquekey = 'id-'..plr.userId
local Savetable = {plr.leaderstats.Cash.Value}
DSService:SetAsync(uniquekey, Savetable)


end)

local DataStore = game:GetService("DataStoreService"):GetDataStore("JaJogou")

game.Players.PlayerAdded:connect(function(plr)
    local JJG = Instance.new("BoolValue", plr)
    JJG.Value = false
    local key = "user-" .. plr.userId

    local DataSaved = DataStore:GetAsync(key)

    if DataSaved then
        local JJGSaved = JJG.Value
    else
        local ValorPraSalvar = (JJG.Value)
        DataStore:SetAsync(key, ValorPraSalvar)
    end
end)

local module = {}
local Storage = game:GetService("DataStoreService"):GetDataStore("Test")

game.Players.PlayerAdded:connect(function(plr)
JaJogou = Instance.new("BoolValue", plr)
JaJogou.Name = "Ja_Jogou"

local Save = Storage:GetAsync(plr.userId .. "-JaJogou")
if Save ~= nil then
JaJogou.Value = Save
end

end)

game.Players.PlayerRemoving:connect(function(plr)
    local id = plr.userId 
    local Salvo = JaJogou.Value
    Storage:SetAsync(id .. "-JaJogou", Salvo) 
end)

return module

local DS = game:GetService("DataStoreService"):GetDataStore("Teste")
local Play = game.ServerStorage.Play

game.Players.PlayerAdded:connect(function(player)
    local Ja_Jogou = Instance.new("BoolValue")
    Ja_Jogou.Parent = game.ServerStorage:WaitForChild("Player1")
    Play.Name = player.Name
    local SavedStuff = DS:GetAsync(player.userId)
    if SavedStuff then
        print("data takes up ".. game:GetService("HttpService"):JSONEncode(SavedStuff):len() .. "/260000")
        for i,v in pairs(SavedStuff) do
            print(i,v)
            if i % 2 == 0 then
                Play[player.Name]:FindFirstChild(SavedStuff[i - 1]).Value = v
            end
        end
    end
end)
local function SaveValue(player)
    local SavedData = {}
    for i,v in pairs(Play[player.Name]:GetChildren()) do
        SavedData[#SavedData +1] = v.Name
        SavedData[#SavedData +1] = v.Value
    end
    DS:SetAsync(player.userId, SavedData)
end
game:BindToClose(function()
    for i,player in pairs(game.Players:GetPlayers()) do
        SaveValue(player)
    end
end)
game.Players.PlayerRemoving:connect(function(Player)
    SaveValue(Player)
end)
game.Players.PlayerAdded:connect(function()
    local Player1 = game.ServerStorage:WaitForChild("Player1")
if Player1.Ja_Jogou.Value == true then
    local GameId = 491387737
    game:GetService("TeleportService"):Teleport(GameId)
    print("Teleportando")
end
end)
