Believe me, I have searched for the answer.
I cant find a complete list of how points are distributed in this game.

Like MIC give me 21points
SIC or CIS give me 15 points.

So I assume S is much less value - I Imagime C = 10pts, I = 3, S= 2, M = 8. But just Guessing. And which factor is used upon extra Word lenght?

Yeah I should be on a SpellTower forum, but could not find one, and this came close
