How to solve it in fewer guesses

That first pair of numbers is the one worth sitting with. Of the 12,953 words EvoWordo will accept from you, 10,699 can never be the answer — about eight in every ten. Words like ADIEU, SALET and SOARE are perfectly legal guesses and will never be correct.

Far from being useless, they are the ideal opening move. A guess that cannot win is a guess spent purely on information, and early on information is worth more than a long-shot at the answer.

The gap between the top and the bottom of that list is what makes opening guesses matter. A guess built from E, S, A, R and O touches letters that appear in a large share of answers. One built from J, Q, X and Z is almost guaranteed to come back blank, which tells you very little you did not already suspect.

Vowels are worth a specific mention. About 44% of answers contain exactly one distinct vowel and 52% contain exactly two — so 96% of the time, the answer has just one or two. Loading your opener with four or five vowels wastes slots. Two is the sweet spot, with the remaining letters spent on frequent consonants.

One caveat on repeating the same opener forever: it is efficient but it stops teaching you anything. If your average has plateaued, varying the opener forces you to actually reason from the board rather than replaying a memorised line.

Remember the duplicate rule as you narrow down. If you guess a letter twice and only one of the two tiles lights up, the answer contains exactly one of it — a hard fact, not an inconsistency. With 32% of answers carrying a repeat, that situation comes up often. The full duplicate rule.

A note on that middle phase, because it is where most attempts are thrown away. If you are down to six candidates that differ by a single letter, guessing them one at a time can burn four attempts to eliminate three options. A single well-chosen “probe” word that contains several of the distinguishing letters can resolve the whole family in one go. You give up a small chance of winning that turn in exchange for near-certainty on the next — a trade that usually pays.

The speed bonus dominates, so solving early is the main lever. But the per-tile points create a real second-order effect: a guess that lands three correct letters scores 9 points whether or not it wins. Guesses that deliberately avoid known-good letters — the classic “probe” play — cost you tile points even when they are tactically sound.

In practice that means the efficiency board rewards a slightly greedier style than pure solve-rate optimisation would. Keeping confirmed letters in place earns points every turn as well as narrowing the field, which is a rare case of the tidy play and the high-scoring play being the same thing.

Note that efficiency is computed from Daily Challenge wins only, so multiplayer rounds will not move it. All six leaderboard categories.

The instinct is to reach for the most obscure word you can think of. It is usually the wrong move, and in a Duel it can lose you the round outright — remember that the winner is whoever solves in fewer guesses. Handing your opponent something impossible often just produces a draw, or hands them the win on a tie-break you could have avoided.

What actually makes a word hard is not rarity, it is ambiguity. Aim for words that leave several plausible candidates alive late into the game.
