Copy-paste code

ServerScriptService/Rounds.server.lua

Copylocal Players = game:GetService("Players")
local state = game.ReplicatedStorage -- clients read the attributes for the GUI
local MIN_PLAYERS, INTERMISSION, ROUND = 2, 15, 120

local function setStatus(text, seconds)
	state:SetAttribute("Status", text)
	state:SetAttribute("EndsAt", workspace:GetServerTimeNow() + (seconds or 0))
end

local function alive(list)
	local out = {}
	for _, p in list do
		local hum = p.Character and p.Character:FindFirstChildOfClass("Humanoid")
		if p.Parent and hum and hum.Health > 0 then table.insert(out, p) end
	end
	return out
end

while true do
	while #Players:GetPlayers() < MIN_PLAYERS do
		setStatus("Waiting for players")
		task.wait(2)
	end
	setStatus("Intermission", INTERMISSION)
	task.wait(INTERMISSION)

	local inRound = Players:GetPlayers()
	for _, p in inRound do
		if p.Character then p.Character:PivotTo(workspace.MapSpawn.CFrame + Vector3.new(math.random(-8, 8), 3, math.random(-8, 8))) end
	end
	setStatus("Round", ROUND)
	local deadline = os.clock() + ROUND
	while os.clock() < deadline and #alive(inRound) > 1 do task.wait(1) end

	for _, p in alive(inRound) do
		if p:FindFirstChild("leaderstats") then p.leaderstats.Coins.Value += 50 end
	end
	setStatus("Round over", 5)
	task.wait(5)
	for _, p in Players:GetPlayers() do p:LoadCharacter() end
end

Good to know

EndsAt uses workspace:GetServerTimeNow(), so every client shows the same countdown without the server sending a message each second.

Players who join mid-round stay in the lobby until the next round because inRound is captured at the start.
