About SLY
SLY means clever in a sneaky way; its forms include SLIER, SLYER, SLIEST and SLYEST. It has no A, E, I, O or U, and uses an S, an L and a Y. Picture a sly fox. It is a common word, and it's valid, so a challenge against it fails, which makes it a safe play for a vowel-short rack.

SLY scores 6 points
Before any bonus squares: S 1 + L 1 + Y 4 = 6. On a double-word square that's 12, on a triple-word 18, and every letter bonus under one of these tiles is applied first.
Example: SLY as the first play
Later in the game, put the Y on a 3L square and SLY is worth 14 before any word bonus.
