Ever since Rewardia started I have always enjoyed playing Scramble Words and every once in while see my name on the weekly high scores - No big deal it's meaningless to anybody else.

Whether or not you can achieve a high score depends entirely on the particular game you are playing. Games with a lot of blank word spaces allow potentially good scores and vice versa.
As such, there is a maximum score achievable in any particular game based on the number of blank spaces. It is impossible to exceed that maximum score.

And yet we constantly see one or two (mainly one) people always at the head of the list with scores that are impossible to achieve. Not just slightly over the maximum but several times the achievable score. In other words they have found a way to cheat.

That's okay, if like Donald Trump, a person's ego is so fragile that they must see their name up in lights then so be it but it begs the question - Are these people collecting rewards via their high scores?

Maybe Rewardia would like to look into it.
