Roblox leaderboard script (leaderstats)

Where to put it

Script — ServerScriptService > Leaderstats (Script). It runs on the server, so players can't change what it does.

1. Insert a Script into ServerScriptService and paste the code.
2. Press Play: the player list now shows a Coins column.

The script

local Players = game:GetService("Players")

local function onPlayerAdded(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats" -- must be exactly this, lowercase
	leaderstats.Parent = player

	local coins = Instance.new("IntValue")
	coins.Name = "Coins"
	coins.Value = 0
	coins.Parent = leaderstats
end

Players.PlayerAdded:Connect(onPlayerAdded)
for _, player in Players:GetPlayers() do
	task.spawn(onPlayerAdded, player)
end

How it works

• Roblox shows every value inside a folder named exactly leaderstats under the Player as a column on the player list.
• Use IntValue for whole numbers and NumberValue for decimals. The first value is the one the list sorts by.
• Change the stat from any server script: player.leaderstats.Coins.Value += 10.

Variations

local Players = game:GetService("Players")

Players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player

	local kills = Instance.new("IntValue")
	kills.Name = "Kills"
	kills.Parent = leaderstats

	player.CharacterAdded:Connect(function(character)
		local humanoid = character:WaitForChild("Humanoid")
		humanoid.Died:Connect(function()
			local tag = humanoid:FindFirstChild("creator") -- ObjectValue set by weapons
			local killer = tag and tag.Value
			if killer and killer:IsA("Player") and killer ~= player then
				killer.leaderstats.Kills.Value += 1
			end
		end)
	end)
end)

Common mistakes

• Naming the folder Leaderstats or leaderStats — it must be all lowercase.
• Creating leaderstats in a LocalScript: the server and other players won't see it.
• Using a StringValue for numbers — sorting and math won't work.
