What an Anchor Letter Actually Is
An anchor is simply a letter already sitting on the board that your new word can be built through or around -- as opposed to playing into open space. Rather than treating your rack as a standalone puzzle, you treat one board letter as fixed and search for seven-letter words that pass through it in the right position. This turns 'what seven-letter words can I make?' into the more useful question 'what seven-letter words can I make that also land here?'
Searching by Anchor and Length Together
In practice: note the anchor letter's position in the word you need (first letter, last letter, or somewhere in the middle), enter your rack letters, set the length filter to exactly 7, and add a starts-with or ends-with filter for the anchor if it falls at either end. In our own dictionary, 23,109 words are exactly seven letters long -- searching without any board constraint leaves you scrolling through all of them, while adding the anchor filter cuts that down to only the handful that could physically be played.
Stacking an Anchor Play with a Premium Square
The biggest single-turn scores come from stacking bonuses rather than chasing any one of them alone: a seven-letter word already earns the flat 50-point Bingo bonus, and if it happens to pass through a double or triple word square at the same time, that multiplier applies to the whole word on top of the 50 points. If your rack includes a high-value letter like Q, X, or Z, it's worth checking whether any valid anchor play lets that specific letter land on its own premium square, rather than just taking the first seven-letter word you find.
