Roblox round system script

The loop behind most minigames: wait for players, count down, send everyone to the arena, time the round and bring them back, with the countdown on screen.

Where it goes

1Add two Parts, Anchored, named LobbySpawn and ArenaSpawn, where players should arrive.
2Add the first script to ServerScriptService.
3In StarterGui, add a ScreenGui with a TextLabel, and put the second script in it as a LocalScript.

How it works

The server runs one loop for everyone, so players can't get out of step.
A StringValue in ReplicatedStorage carries the countdown text to each player's screen.
spread puts players a little apart, so they don't land on top of each other.

Make it yours

Test it alone: Set MIN_PLAYERS to 1 while you're building.
Prizes: Before sendEveryoneTo(lobbySpawn), give coins to the players still alive.

Want something more? The script generator can write it: “A round system that gives 10 coins to everyone still alive when the round ends, and ends early if one player is left”
