Idiom Fill

A familiar English phrase appears with one word taken out — trial and ___, ___ and pepper, once in a ___ — and four real words are offered underneath it. Only one of them makes a phrase. The other three are real words too, drawn from the same list, and each of them lives happily inside some other phrase; they just do not belong in this one. Pick the right word six times before your tries run out.

Every blank is checked before it is dealt, and checked twice over. First, exactly one word in the whole vocabulary can complete it: a blank that two words finish — here and ___, which both there and now complete — is thrown out and never appears. Second, the answer is never printed somewhere else in the same phrase, so step by ___ is not a puzzle this game will ever ask you. What is left is a phrase you either know or do not, which is the only version of this worth playing.

Get one wrong and the word is ruled out rather than the question lost: the phrase stays on screen with one fewer candidate, and you are told which phrase the word you picked actually belongs to. A wrong answer therefore teaches you a second phrase instead of nothing.

1. Read the phrase with the gap in it. The missing word is shown as a long dash on an underline; everything either side of it is fixed.
2. Focus the board — click it, or press Tab until it is outlined.
3. Move between the four words with the up and down arrows, or left and right, or W and S. The cursor clamps at the ends rather than wrapping, and it steps over any word you have already ruled out.
4. Pick a word with Enter or Space, or click it. One press, one answer — clicking spends exactly one try, never two.
5. If it is right, the phrase is completed and the next one appears. Completing a phrase without ruling anything out first is worth a bonus, so a confident answer scores higher than a worked-out one.
6. If it is wrong, that word is struck through and marked ✗, it costs one try, and the line under the list tells you two things: what your choice would have spelled, and which phrase that word really belongs to. The phrase stays up, so you carry on with one fewer candidate.
7. Finish all six phrases before the tries run out. You get three to five, depending on how many of the wrong words on your particular board genuinely stand in that same position elsewhere in the list. Spare tries are worth points.

How do you work out which word completes a common English phrase?

Stop looking for the word that means the right thing and start looking for the word that goes there. Fixed phrases are stored whole. "Trial and error" is not assembled at the moment you say it from the meanings of "trial" and "error" — it is retrieved in one piece, which is why "attempt and mistake" means roughly the same thing and sounds wrong to every English speaker alive. Linguists call this collocation, and it is the reason someone with a large vocabulary can still sound unnatural: they know the words and not the pairings. So the useful question at a gap is not "which of these is sensible?" but "which of these have I actually heard in this slot?" Three practical moves follow. Read the phrase aloud with each candidate in place, because the ear stores collocations even when the eye argues. Notice which words are already spoken for — if a word obviously belongs to another phrase you know, it is probably a decoy here rather than a second answer. And check the shape: some words only ever open a phrase and some only ever close one, so a word that has never once stood in that position is refutable before you have thought about its meaning at all. That last one is exactly the count this game measures to decide how many tries your board deserves.

Is there always exactly one right answer?

Yes, and it is proven rather than hoped for. Before any board exists, the game takes every phrase in its list and every position in every phrase, and keeps only the positions that survive three checks. The blanked word must not be a linker, so you are never asked to supply the "and" in black ___ white — the grammar would give that away before the phrase did. The blanked word must not appear anywhere else in the same phrase, which throws out every doubled phrase like "step by step" and "day after day", where the answer is printed a word or two from the gap. And every single word in the vocabulary is then tried in the gap against the whole phrase list: the position is kept only if exactly one word turns it back into a real phrase. That is an exhaustive check, not a sample, so a genuinely ambiguous gap cannot slip through — here and ___ is completed by there and by now, so it is simply never dealt, while ___ and there and ___ and now both survive and are both perfectly fair. On top of that, each of the three wrong words offered is tested individually against the same phrase list and refused if it would also make a phrase, and the finished board is re-read one last time before you ever see it.

How many wrong answers do I get?

Three, four or five, and the number is computed from your particular board rather than fixed. Once the six phrases are dealt, the game counts how many of the eighteen wrong words offered really do stand in that same position in some other phrase on the list. A word that has never once appeared in that slot can be ruled out by shape alone; a word that has must be eliminated by knowing the phrase, which is the work the game is actually asking for. Boards full of the second kind get more tries, boards full of the first kind get fewer, and the result is clamped so no board drops below three or rises above five. Since only three wrong words are offered per phrase, running out is always a matter of a few genuine mistakes rather than one unlucky one.

Is there any money, betting or in-app purchase in this?

None, and there never will be. No currency, no prizes, nothing to buy, no lives to refill and no money involved at any point. It is a word puzzle that runs on your own device.

Can I play it with a keyboard or a screen reader?

Both, with the same rules — there is no drag, no swipe and no timing anywhere in it. Arrows or WASD move between the four words, Enter or Space picks one. Every word is a real button whose spoken label gives its position, the word itself, and whether it has been ruled out yet. The gap in the phrase is announced as the word "blank" rather than as a row of punctuation, and the live region reads the phrase number, the tries left, the word under the cursor and the result of your last pick after every move. A ruled-out word carries a ✗ and a line through it, the answer carries a ✓ once the round ends, and the note under the list says the same thing in a full sentence — so nothing on this board depends on telling colours apart.

Does it work offline, and where do the phrases come from?

Yes, and from the game itself. The phrase list is written into the module: nothing is fetched, there is no content pack to install and no server is involved at any point. Once the page has loaded once, the list, the generator, the checker that proves each gap has one answer and the scoring are all on your device. Every board is built from a seed on your own machine, which is also why the same seed always deals the same six phrases in the same order.

Sixty-one phrases, all of them deliberately culture-neutral — nothing here depends on a national sport, a local institution, a currency or a regional turn of phrase, so the list reads the same wherever you are. That neutrality is also the limit: plenty of vivid English phrases are missing precisely because they only travel within one country, and a phrase you use every day may simply not be on the list. Of the sixty-one, only forty-two can ever be dealt as a puzzle — the doubled ones like "bit by bit" and "face to face" have the answer printed beside the gap, so they are kept for their vocabulary and for naming where a wrong word belongs, and never asked. That leaves seventy- eight fair gaps in total, so a long session will start to repeat phrases, though not the same combination of decoys. Every board is six phrases with four words each, and the try budget runs from three to five. There is no timer, no daily streak to protect and no hint button.

Syllable Split cuts six words in two and asks you to rejoin the halves, which is the same kind of pairing one level down — inside the word rather than inside the phrase. Word Weave crosses two four-letter words at a shared square and asks you to fill the blanks. Word Hunt hides six words in a letter grid and rewards careful reading over recall. Word Ladder turns one word into another a single letter at a time.
