How the word unscrambler works
Every word in the dictionary is checked against the letters you have. A word counts as a match when you hold enough of each letter to spell it, with blank tiles covering any shortfall. The unscrambler does not care about letter order, which is why it finds words that hide inside your rack even when they use only a few of your tiles.
Results are grouped by length because that is usually how you play: long words score best and use up awkward letters, while two- and three-letter words are useful for squeezing points out of tight spots on the board.
Getting more out of a rack
- Look for hooks. A short word that takes an S or ED at the end can turn a small play into a two-direction score.
- Balance your leave. The letters you keep matter. Playing off a Q or a second V can be worth more than a slightly higher score now.
- Learn the two-letter words. Words like QI, ZA, XU and JO get heavy letters onto the board cheaply.
Example
The six letters RSTLNE make 40 words of two to six letters, but not a single six-letter word. Add one blank (RSTLNE?) and nine seven-letter words appear, including antlers, rentals, sternly and relents. That is why a blank tile is usually worth holding on to.
