The Codebreaker Playbook: Frequency, Pattern, and the Cost of a Check
Penciled letters are free and the code cracks itself when every letter is right. The only thing that costs you is asking the game to check your work.
Start where the puzzle starts you
Codebreaker hands you the three most frequent letters of the saying, already filled in and locked in the game's color. Those three are almost always drawn from E, T, A, O, I, N and S, and they touch most of the words in the sentence. Read every word that contains a given letter before you type anything — the puzzle is designed so that a way in is always visible.
The short words are that way in. A one-letter word is A or I. A two-letter word is one of a dozen — OF, TO, IN, IT, IS, AS, AT, ON, BE, WE, HE, SO — and if it contains a given letter you can usually name it outright. A three-letter word ending in a given E is THE more often than anything else, which fixes T and H everywhere they appear. Two or three of these and a third of the code is broken.
Trust the frequency strip
The strip of code letters under the board is ordered by how often each appears, and English is stubbornly consistent about frequency: after the three given letters, the next most common code letters almost always stand for the rest of E, T, A, O, I, N, S, H and R. When you have a candidate word with one unknown letter, check the unknown against the strip — a very common code letter is a vowel or one of T, N, S, R, and a code letter that appears exactly once is far more likely to be a B, K, V or W than an E.
Frequency also settles doubles. Two identical code letters side by side are almost always LL, SS, EE, OO, TT or FF, and if the pair is a common code letter it is EE or OO, while a rare one is a consonant pair. That single rule places two letters at once.
Apostrophes and endings are fixed points
A letter after an apostrophe is nearly always S or T — IT'S, DON'T, CAN'T, WON'T, YOU'RE for the two-letter case. A word ending in a given E preceded by a common code letter is probably -RE, -SE, -TE or -LE. A four-letter word ending in two identical unknowns is very often -ALL, -ILL or -ELL. These endings are patterns you can read off the shape of the word before you know a single letter in it.
A saying of 30 to 90 letters is a sentence you already know, and sentences have grammar: a three-letter word at the start is often THE or YOU, and the last word is the one the whole sentence points at. Guess the sentence, not the letters.
Pencil boldly
Every letter you type is a pencil mark. It lands in every box with that code letter, you can type over it, Delete it everywhere at once, and nothing is marked or counted while you experiment. The game only warns you when you have used the same plain letter for two different code letters, turning both red — because a saying cannot have two letters that both mean E. So try a whole word at once and read the sentence back. A wrong guess usually looks wrong immediately, and undoing it is free.
Penciling a full hypothesis is faster than being careful: if you think a five-letter word is THERE, type all five and let the other words tell you whether the R holds.
Check almost never
Check is the only action that counts against you. It looks at every penciled letter, locks the right ones and clears the wrong ones with a red flash — and it is recorded. Your finish is counted as checks plus one out of a budget of four, with every unused check worth 250 points: no Check banks 750, one Check 500, two 250, three or more nothing. Speed is worth at most 240 points across a twenty-minute cap, so a single Check costs more than the whole speed bonus. The bonus falls per Check, not per wrong letter, which means one Check that catches five errors costs exactly what one Check that catches none does.
That arithmetic gives you a policy. Never Check early. Pencil the whole saying, read it aloud, fix what reads wrong — the puzzle completes itself the moment every letter is right, so a fully correct board never needs a Check at all. Reserve Check for two or three genuinely doubtful letters, and take one Check, not two.
Hint before Check, Reveal only when beaten
Hint fills in the most frequent letter you have not yet solved and locks it, for 100 points. It never counts as a Check, though it rules out a Perfect run and the Pure Codebreaker achievements. Because a Check costs 250 and a Hint costs 100, the Hint is the better buy whenever you are stuck rather than merely unsure — it hands you a common letter that usually appears in several words and opens all of them at once.
Reveal appears after five minutes and shows the whole saying, recording the puzzle as a loss with credit for the time you put in. It is for a puzzle that has beaten you, and those are rare: these are sayings everyone knows, so once four or five words are readable, saying the sentence aloud almost always finishes it. On a holiday the saying belongs to the day, which is one more clue. Like every More Games title, Codebreaker earns XP and medals without touching your Daily Sweep.
