How do I prevent people from spawning at the same spawn?

In my minimap's there are 25 spawns. My problem is that there's a 1 in 25 chance of someone being spawned in the same place, and I'm trying to prevent this. How do I prevent no two people from spawning at the same spawn? Thank you!

function MovePlayers()
    local Players = game.Players:GetPlayers()
    local Spawnso = game.Workspace.Map.Spawns:GetChildren()
    for i, v in pairs(Players) do
        local ToSpawn = math.random(1, #Spawnso)
        if v.GameBool.Value == true then
        v.Character.HumanoidRootPart.CFrame = Spawnso[ToSpawn].CFrame * CFrame.new(0,5,0)
        v.Ingame.Value = true
        -- the last part is probably not needed but oh well
        wait(0.05)
        v.Character.Torso.Anchored = true
        end
    end
end
