High-value letter density matters: roughly 139 results here include at least one premium tile worth 8–10 points on its own. Suffix patterns such as -ED, -NG, -LY, -ING appear frequently here and are high-yield targets in both Scrabble and Words with Friends. Top scorer: oxybenzoic (33 pts). Average Scrabble value across the list is 22.8 points per word.
