What the Starter Word Lab measures
This lab uses Xfire’s saved answer list and existing word profiles. The percentages are a reference, not a forecast of future answers. For each saved answer, the charts count letter presence and exact slot positions. Existing word-profile estimates are displayed separately when available; they are not forecasts of a puzzle’s difficulty.
When you enter a starter here, we check membership in the combined saved answer and guess lists. We report the unique-letter count and the weighted letter/position coverage score separately. Existing word-profile estimates are shown separately when available; they are not a forecast of a puzzle’s difficulty.
How to use this lab with your own openers
Start by typing the openers you already like—SLATE, CRANE, TRACE, SOARE, or anything else—into the three rows. Starters with more unique letters and higher coverage scores tend to get you better information per guess, especially when their letters are also common in our position heatmap.
The lexical difficulty and domain tags help you decide whether a starter leans toward everyday language or more specialised themes. For example, a starter tagged with FOOD or ANIMALS might feel friendlier on casual boards, while more abstract domains can lean into trickier vocabulary.
Wordle Starter Word Lab FAQ
Does the lab tell me the one perfect starter?
- No. There is no single best starter for every player and every board. The lab focuses on measurable ingredients—letter coverage, position coverage, and lexical difficulty—so you can compare reasonable candidates and pick one or two that fit your style.
Why does coverage use the answer list but validation uses answers and guesses?
- Coverage is based on how letters behave in real solutions, so these percentages use Xfire’s saved answer list. Input checks use the saved answer and guess lists; they do not verify today’s live acceptance rules.
What does the lexical difficulty N/10 mean?
- The lexical difficulty uses external frequency data to put each word on a rough 1–10 scale: lower numbers are more common and "easier" words, higher numbers are rarer or more specialised. It’s separate from our in-game difficulty labels like NORMAL or TRAP, but together they give a fuller picture of how forgiving a board feels.
Can I break my streak with this?
- Using the lab doesn’t reveal today’s answer or narrow the field directly. It only evaluates starters in the abstract, across the whole answer list and lexical model. To avoid spoiling today’s puzzle, use this alongside our Letter Frequency explorer and Daily Hints tool instead of brute-force solvers.
