ORANGE and ONAGER use all six letters
Both answers use O, R, A, N, G and E once. They have 7 base points: G contributes 2 and each other tile contributes 1. The number does not include a board placement.
Five-letter options with one tile left
ANGER and RANGE use A, N, G, E and R, leaving O. GROAN leaves E, and ORGAN is a different arrangement of those same five letters. Set Max length to 5 to inspect these shorter choices.
What this list confirms
These answers come from the same English list as Scrabble (our version). They are not labelled as an official tournament or WWF list. Count repeated letters separately, and check every cross-word before placing tiles.
Check a particular word, practise a rack with hidden answers or unscramble different letters.
