Why Your First Guess Is the Most Important
In Wordle and GlyphDuel, your first guess is not meant to find the answer — it is meant to collect as much information as possible. Each tile color tells you whether a letter is absent, present but misplaced, or exactly right. A strong opening word can give you 3 or 4 actionable clues on the very first guess; a weak one leaves you groping in the dark.
The logic is mathematical: if the dictionary contains around 2,355 five-letter words in English, your goal on guess one is to eliminate as many candidates as possible, regardless of what feedback you get back.
Three Criteria for a Good Opening Word
Criterion 1 — Five Strictly Distinct Letters
A word like SPEED (two E's) only gives you information about 4 unique letters. TEETH gives you information about only 3. That is a wasted guess. Your first word must contain 5 different letters — no exceptions.
| Word | Distinct letters | Efficiency |
|---|---|---|
| SPEED | 4 (S, P, E, D) | ❌ Poor |
| CRANE | 5 (C, R, A, N, E) | ✅ Optimal |
| RAISE | 5 (R, A, I, S, E) | ✅ Optimal |
Criterion 2 — The Most Frequent Letters
The more frequent the letters in your opening word, the more likely they are to appear in the secret word. Here are the top 10 most common letters in 5-letter English words:
An ideal opening word hits 5 of these 10 letters.
Criterion 3 — Strategic Positions
Letters don't appear with equal probability at every position. In English, S is very common at position 5 (plural forms), E frequently appears at position 5 as well, and T is often at positions 1 or 3. Placing letters in their most likely positions increases your chances of hitting green tiles on the very first guess.
The Best English Opening Words
CRANE — The Community Favourite
CRANE covers C, R, A, N, E — five of the ten most frequent letters in the English dictionary, with a distribution that hits common positions well. Multiple independent mathematical analyses confirm CRANE as one of the top-performing openers.
In this example: R is in the right place (🟩), A is present but misplaced (🟨), C, N, E are not in the word (⬛). Two actionable clues on the first guess.
RAISE — The Vowel-Heavy Approach
RAISE (R, A, I, S, E) covers four of the top-five most frequent letters and hits three vowels in one go. Many players prefer it precisely because establishing which vowels are present early narrows the search space dramatically.
SLATE — The S-Starters
SLATE (S, L, A, T, E) is popular because S at the start reveals whether it forms an S-cluster (ST-, SL-, SC-) — very common in English. It covers 5 highly frequent letters and is easier to remember than some mathematical "optimal" choices.
STARE / TRACE / CRATE
These words cover similar letter sets with slight variations. STARE is particularly effective because the ST- onset is one of the most common in English, giving positional information as well as presence/absence.
Our EN recommendation: Start with CRANE or RAISE. If the result is poor (fewer than 2 clues), follow up with STOIC (S, T, O, I, C) or LYMPH to cover uncommon letters. Together, CRANE + STOIC cover 9 of the top 10 most frequent English letters.
The Two-Word Opening Strategy
An advanced technique is to prepare a fixed pair of opening words covering 10 distinct letters. You play both regardless of the result, then exploit the information.
| Word 1 | Word 2 | Letters covered |
|---|---|---|
| CRANE | STOIC | C, R, A, N, E, S, T, O, I — 9/10 top letters |
| RAISE | CLOTH | R, A, I, S, E, C, L, O, T, H — 10/10 top letters |
| SLATE | CRONY | S, L, A, T, E, C, R, O, N, Y |
After these two guesses you know the status of 10 letters. You have 4 remaining guesses to close in on the answer.
In GlyphDuel multiplayer: The two-word scouting strategy is risky. Points go to the first player who finds the word. If your opponent guesses on their 2nd try while you're still scouting, you lose the round. In multiplayer, cap your scouting at one word, then exploit immediately.
Best Openers by Language
French — TALER
In French, the top 10 letters are E, A, I, S, R, N, T, O, L, U. TALER (T, A, L, E, R) covers five of the top seven and is our top recommendation for French mode.
Spanish — ADIOS
Spanish has an unusually high vowel density: A, E, I, O together account for about 43 % of all letters in 5-letter words. ADIOS (A, D, I, O, S) covers four main vowels plus the high-frequency consonant S.
German — RATEN
German is dominated by E (16.4 %) and N (10.2 %). Any strong German opener must include both. RATEN (R, A, T, E, N) covers the five most valuable letters in German mode.

What the Data Doesn't Tell You
Raw frequency has its limits. Two things it ignores:
Positional bias. S is rare at position 1 in English but very common at position 5 (plurals). E is more likely at position 5 than position 1. A word that places letters at their most probable positions adds an extra edge beyond simple frequency matching.
Information entropy. Researchers have applied Shannon information theory to calculate which word eliminates the most candidates on average, regardless of the feedback. The mathematically optimal opener (often cited as SALET or REAST in English) differs slightly from community favourites. In practice, the difference is less than 0.1 guesses on average — well within noise.
The real advice: Consistency beats micro-optimisation. Pick a word you remember easily and apply it every game. You'll improve faster by studying the patterns you receive than by endlessly searching for the theoretically perfect opener.
Conclusion
A great opening word follows three rules: 5 distinct letters, as frequent as possible, distributed across strategic positions. CRANE or RAISE for English, TALER for French, ADIOS for Spanish, RATEN for German — memorise these and apply them consistently.
The real skill starts after the first guess: how you interpret the clues, how quickly you narrow the candidate pool, how you choose between two equally probable words under time pressure. That's where the gap between strong and average players opens up.
