Editing Upwords (section)

==Scoring==
Any word with no stacked letters scores two points per tile, while a word containing stacked letters scores one point for every tile it contains. In the CATER/BELATED example above, CATER would score 10 points, while BELATED would score nine. Two bonus points are awarded for using the "Qu" tile in a one-level word, and 20 for using all seven tiles in one turn. If changing two words at once, both words must be legal.

Players lose five points for every unused tile they hold at the end of the game.
