The values of the letters in Scrabble were assigned according to the front page of a US newspaper in the 1930s. Is it time the scoring system was updated to reflect today's usage?

All Scrabble players know that Q and Z are the highest scoring tiles. You can get 10 points for each, in the English language version of the game.

But according to one American researcher, Z really only deserves six points.

And it's not just Z that's under fire. After 75 years of Scrabble, some argue that the current tile values are out of date as certain letters have become more common than they used to be.
