How to get the best score of players?

My players have a leaderstats with score, how to get the best score and put the name of the player with best score in a var?

I tried with getplayers () but it did not work

Here's a way to do this. This assumes you have standard leaderstats with Kills:

local Highscore = 0

for _,v in pairs(game:GetService("Players"):GetPlayers()) do
  if v:FindFirstChild("leaderstats") and v.leaderstats:FindFirstChild("Kills") then
    if v.leaderstats.Kills.Value > Highscore then
      Highscore = v.leaderstats.Kills.Value
    end
  end
end
