&gt; Another option is to more heavily validate higher scores, keep the top 0.5% honest and cheating to get a lower high score has less value.<p>That&#x27;s one kind of thing I&#x27;ve thought about in the past. I&#x27;m thinking things like Game Center&#x27;s global scoreboard, so if you only every check scores that are supposed to break the top 1000 then you don&#x27;t have to bother checking everyone&#x27;s games. If you fake a score of 270 points, well there isn&#x27;t a huge benefit in stoping you.
