Scrabble letter values
Every tile has a fixed value. 1 point: A E I O U L N S T R. 2: D G. 3: B C M P. 4: F H V W Y. 5: K. 8: J X. 10: Q Z. Blanks score nothing but make plays possible that otherwise aren't. The scores in the results are face value. Board squares multiply them, and using all seven tiles in one turn (a "bingo") adds 50 points on top.
Worked example
Say your rack is AEINRST, one of the best racks you can draw. The finder returns the seven-letter bingos NASTIER, RETAINS, RETINAS, RETSINA, STAINER, STEARIN and ANESTRI. Each is worth 7 face points, plus 50 if you can fit all seven tiles on the board. No room for seven? Keep reading down the list for six- and five-letter plays like SATIRE and TRAINS. Type a board letter into "playing through," say an open O, and the search shifts to words like SENORITA that run your rack through it.
Strategy: score isn't everything
The top-scoring word isn't always the right play. Look at where it lands first. Does it open a triple-word square for your opponent? Then look at what it leaves you. Playing five tiles and keeping R and S beats playing six and keeping the Q. And look for hooks, words that take an extra letter on the front or back. HEAT becomes CHEAT or WHEAT, and you score the new word plus whatever you laid alongside it. Two more things worth memorizing: the Q-without-U words (QI, QAT, QAID, QOPH) and the two-letter words. That second list is the biggest single upgrade a casual player can make.
Frequently asked questions
Why does my game reject a word this tool found?
Word lists differ. This site uses ENABLE (public domain); North American tournament play uses the NWL, and international play uses Collins — each includes some words the others don't. Treat borderline finds as "check before you play."
What are the seven-letter bonus points?
Using all seven rack tiles in one play is a bingo, worth an extra 50 points on top of the word's score. It's the biggest single swing in Scrabble, which is why strong players fish for bingo-friendly racks.
How should I use the "playing through" box?
Put in the letter (or letters) already on the board that your word must include. The finder adds them to your rack and only returns words containing them — mirroring how you'd actually place the word on the board.
