Look at what I linked above and at the code I posted. Where does it say that you can just put a random integer into the %client parameter?You can set %client to 0, but you can only create one minigame without a client like that (it will use the host BLID). Every minigame must be on a different BLID. BLIDs are what allows the minigame to determine what bricks, items, vehicles, etc. are in each minigame.
