UP scores 4 points
Before any bonus squares: U 1 + P 3 = 4. On a double-word square that's 8, on a triple-word 12, and every letter bonus under one of these tiles is applied first.
Example: UP as the first play
Later in the game, put the P on a 3L square and UP is worth 10 before any word bonus.
Hooks: one tile makes a new word
In front of UP (7):
