{{notice|<big>'''SPOILER ALERT!'''</big><br>If you read on without trying to look at the crossword clues first, the joke is spoiled and your chance of finding out the joke yourself is gone instantly!|image=warning!!.png}}

This is a crossword puzzle. On a surface level, the answers seem extremely difficult, with questions covering a wide variety of trivia, linguistics, mathematics in various forms, alongside wordplay typical of crossword puzzles. But the joke is that every single letter of every single answer is "A". See explanation for all 51 clues in the [[#Table|table]] below. All the black squares are in a symmetrical pattern, which is generally the case for crossword puzzles in the US and UK. See description of the pattern in the [[#Transcript|transcript]].

The name of this comic, “A Crossword Puzzle”, is a double entendre; the “A” can be interpreted both as the indefinite article “a”, and as an identifier saying that this crossword puzzle is specifically an “A” puzzle, due to the answer being all “a”s.

The title text is a play on a "type A" personality. The term for someone with a competitive and high-achieving personality is "Type A". In the context of the title text, this answer is a hint that the entire puzzle can be completed in a crossword-solving app by typing the letter A repeatedly.

[[Randall]] pays tribute to a similar comic in the header text of this comic. See the [[#Trivia|trivia]] section below. In that trivia section there is also a picture of the solved puzzle.

|-
! Location !! Clue !! Explanation !! Squares
|-
| 1-Across || Famous Pvt. Wilhelm quote || Reference to the {{w|Wilhelm scream}}. || 10
|-
| 11-Across || IPv6 address record || An IPv4 record is an "A" record; an IPv6 record is four times the length and is designated an "AAAA" record. || 4
|-
| 15-Across || “CIPHERTEXT” decrypted with Vigenère key “CIPHERTEXT” || A "{{w|Vigenère Cipher}}" translates the original text by the distance from A from the key, letter by letter. For instance, if the plaintext is "XK" and the key is "CD", the C shifts X 2 forward to become Z, and the D shifts K 3 forward to become N, yielding a ciphertext of "ZN". Since the ciphertext and the key are the same in this case, decryption just shifts all the letters back to A, akin to subtracting a number from itself and getting 0. || 10
|-
| 16-Across || 8mm diameter battery || An {{w|AAAA battery}} is a 1.5V battery that measures 8.3 mm in diameter, 2.2 mm smaller than the more common AAA battery. || 4
|-
| 17-Across || “Warthog” attack aircraft || The {{w|A-10 Warthog}} is an attack aircraft. Here, A-10 has been turned into AAAAAAAAAA (ten As). || 10
|-
| 18-Across || Every third letter in the word for “inability to visualize” || Aphantasia is the inability to visualize. Following the instruction, we determine that '''A'''ph'''a'''nt'''a'''si'''a''' gives us the word "aaaa". This clue is particularly mean because of how it instructs you to visualize the word in order to get the answer. || 4
|-
| 19-Across || An acrostic hidden on the first page of the dictionary || The first page of the dictionary (if you ignore the copyright page and the index) is the list of words starting with A. An acrostic of this page, taking the first letter of each line and arranging them in order, would just be a sequence of A's. || 10
|-
| 21-Across || Default paper size in Europe || {{w|A4 paper}} (here written as AAAA) is the default size in Europe. At 210x297 mm, it is approximately 0.24" narrower and 0.71" longer than the 8.5"x11" paper used in the United States, and due to having an aspect ratio of 1:sqrt(2), can be cut in half to create two half-sized sheets with exactly the same aspect ratio. || 4
|-
| 22-Across || First four unary strings || A unary number system represents numbers using just one symbol. E.g. 32 in unary would be 11111111111111111111111111111111. The first four strings in unary, if you used A as the first (and only) symbol, would be A, AA, AAA, AAAA. || 10

|-
| 26-Across || Audi coupe || First of three Audi references. {{w|List_of_Audi_vehicles|Audi's car models}} range from A1 (subcompact hatchback) to A8 (full-size luxury sedan); the A5 is a compact executive coupé. || 5
|-
| 27-Across || A pair of small remote batteries, when inserted || Two AAA batteries (AAAAAA). "Inserted" is often a cryptic hint that one word should surround another. || 6
|-
| 29-Across || Unofficial Howard Dean slogan || A reference to Howard Dean, an American Democrat who ran for the party's nomination in 2004. He famously [https://www.youtube.com/watch?v=l6i-gYRAwM0 yelled at a rally] in a way that was thought to be bizarre and which, it is thought, doomed his campaign. || 7
|-
| 32-Across || A 4.0 report card || A 4.0 GPA, at least {{w|Academic_grading_in_the_United_States|in the USA}}, is all A's. This clue assumes seven classes. || 7

|-
| 51-Across || Lola, when betting it all on Black 20 in ''Run Lola Run'' || In ''{{w|Run Lola Run}}'', Lola (Franka Potente) [https://youtu.be/OTSz1w-cuZM?si=2vc51WCWvn20Hjoo&t=116 screams loud enough to affect the outcome] of a roulette wheel where she has just bet all her money on Black 20. The scream could be transcribed as "AAAAAAAAAAA" || 10
|-
| 1-Down || Game featuring “a reckless disregard for gravity” || {{w|AaAaAA!!! – A Reckless Disregard for Gravity}} - notably the title is commonly extended in promotional material beyond 6 A's. || 6
|-
| 2-Down || 101010101010101010101010<sub>2→16</sub> || 10101010 10101010 10101010 in binary is equivalent to "AAAAAA" in hexadecimal. || 6
|-
| 3-Down || Google phone released July ’22 || The {{w|Pixel 6a}} was released in July 22. Stylized in this puzzle as "AAAAAA" ('A'*6) || 6
|-
| 4-Down || It’s five times better than that ''other'' steak sauce || 5 times better than {{w|A1 steak sauce}} would be A5, stylized in this puzzle as "AAAAA". || 5
|-
| 5-Down || ToHex(43690) || The decimal number 43690 converted to hexadecimal is AAAA. || 4
|-
| 6-Down || Freddie Mercury lyric from ''Under Pressure'' || A drawn-out 'Aaaaahhhh' rising in pitch. || 15
|-
| 7-Down || Full-size Audi luxury sedan || Second of three Audi references. As mentioned previously, the A8 is their full-size luxury sedan. || 8
|-
| 8-Down || Fast path through a multiple choice marketing survey || The "fast path" is just to select the first option over and over again. Usually the options are labeled A, B, C, and D (or more) - choosing the first option for every question would be answering entirely with A's. || 7
|-
| 9-Down || 12356631 in base 26 || Randall is expressing base 26 using the letters of the alphabet with 1=A, in which case 12356631<sub>10</sub> = AAAAAA<sub>26</sub>. (It's unclear how one would express the digit 0<sub>26</sub> this way.) || 6
|-
| 10-Down || Viral Jimmy Barnes chorus || A reference to the music video for Kirin J Callinan's song '{{w|Big Enough}}', which features Jimmy Barnes in a cowboy hat screaming "Aaaaaaaaaaaaaaa!" while in the sky over mountain scenes. || 15
|-
| 11-Down || Ruby Rhod catchphrase || Ruby Rhod is a radio host in the film '{{w|The Fifth Element}}'; he has a scene with a memorable scream. || 5
|-
| 12-Down || badbeef + 9efcebbb || In hexadecimal, badbeef and 9efcebbb add together to equal AAAAAAAA (195,935,983, 2,667,375,547, and 2,863,311,530 in decimal respectively). || 8
|-
| 13-Down || In Wet Leg’s ''Ur Mum'', what the singer has been practicing || In the song "{{w|Ur Mum}}" by Wet Leg, the bridge starts with "Okay, I've been practicing my longest and loudest scream", which is apparently eight As long. || 8
|-
| 14-Down || Refrain from Nora Reed bot || The "Endless Scream" bot on social media, made by Nora Reed, posts "AAAAAAAAAAA" (with or without an h) at varying lengths. || 8
|-
| 20-Down || Mario button presses to ascend Minas Tirith’s walls || {{w|Minas Tirith}}. In Mario games you typically use the A button to jump. In games where you don't press a button to move (e.g. games with a joystick) then the button presses required to ascend a vertical structure would probably all be A. This clue might have been inspired by the {{w|A-button challenge}} / [https://ukikipedia.net/wiki/A_Button_Challenge A Button Challenge], which tallies the amount of A presses needed to beat ''Super Mario 64''. Additionally, Minas Tirith is a city with seven concentric rings, each with a wall around it and higher than the last ring. Presumably, it takes seven jumps to get to the highest area of the city, so the answer is "AAAAAAA". || 7
|-
| 24-Down || Vermont historic route north from Bennington || {{w|Vermont Route 7A}}, or AAAAAAA. || 7 
|-
| 26-Down || High-budget video game || A high budget video game is usually referred to as a Triple-A game, or AAA. || 3
|-
| 28-Down || Unorthodox Tic-Tac-Toe win || Tic-Tac-Toe is usually won by getting either three Xs or three Os in a row, making XXX and OOO normal Tic-Tac-Toe wins. One could achieve a win of AAA by making the unorthodox choice of playing with the letter A instead of X or O. Alternatively, Randall is envisaging the grid as defined by rows 1, 2, 3, and columns A, B, C, so an AAA win would be simply playing in the first column each time - a strategy which should be obvious and easy to stop, even for young children who have not yet worked out that ''any'' route to winning can be blocked. || 3
|-
| 29-Down || String whose SHA-256 hash ends “…689510285e212385” || <code>printf AAAAAAAA <nowiki>|</nowiki> sha256sum</code> outputs <code>c34ab6abb7b2bb595bc25c3b388c872fd1d575819a8f55cc689510285e212385</code>.
Note that this 'clue' would be normally be ''particularly'' difficult, in isolation, as the nature of a {{w|hash function}} means that it is possible for multiple inputs to produce a given output, and that finding any of these (and definitely identifying ''all'' of them, to ensure you have the correct original) would require a {{w|brute-force attack}}; i.e. a test of all possible initial states to discover which of them might be viable candidates. Even more problematic is that we are only given a partial hash string, meaning we are possibly talking of a multiple of full hashes, each of them with a possible multiplicity of original plaintexts behind them.
<br/>The number of possible hashes in the clue is 16<sup>64</sup>/16<sup>16</sup>, i.e. 16<sup>48</sup>, or approximately 6x10<sup>54</sup>, although there really is no reason (aside from the fundemental impracticality) to try to solve this problem from each and every 'hash end'. Instead you would 'only' check every combination of 8 letters (presuming no digits, punctuation or whitespace would be inserted, and that uppercase is universally presumed, is 26<sup>8</sup>; i.e. ~208 {{w|billion|short-scale billion}} possibilities) and discover which (one?) of these sufficiently matches the hash fragment given. Testing a hundred of these every second, it would take a little over 66 ''years'' to complete the task of checking every single possibility (rather than stopping at the first confirmed answer, which might well be the initial one in this particular case).
<br/>In the context of a crossword such as this, however, you can significantly reduce this search by having established (or at least sufficiently narrowed down) the answers to the various across-clues which intersect with ever character of it (this form of crossword grid being of the {{w|Crossword#American-style crosswords|dense type}}, with no singly-clued spaces as with the more open lattice-types), reducing the necessary checks drastically. This could mean, having solved at least some of the perpendicular answers, that you have enough information to 'guess' at some likely answer, and then merely need to ''confirm'' that whatever guess(es) you make will resolve themselves into the clue-answer provided. (Much as you might with a more normally difficult clue, where you merely have to satisfy yourself that the surprise answer is at least justified as resulting from the original hint.)|| 8
|-
| 30-Down || Arnold’s remark to the Predator || A reference to [https://www.youtube.com/watch?v=OsFYPVxHKdc this scene] from '{{w|Predator (film)|Predator}}'. || 8
|-
| 31-Down || The vowels in the fire salamander’s binomial name || The vowels in {{w|Salamandra salamandra}} are aaaaaaaa. || 8
|-
| 32-Down || Janet Leigh ''Psycho'' line || The iconic scene in {{w|Psycho (1960 film)|Psycho}} is the shower scene, in which Janet Leigh gives a long piercing scream as she is murdered, which can be written as 8 "As" if one wishes. || 8
|-
| 34-Down || Seven 440Hz pulses || A sound with a frequency of 440 Hz is a middle "A" note. Seven such pulses would be AAAAAAA. || 7
|-
| 37-Down || Audi luxury sports sedan || Third of three Audi references. The A6 is their executive car. Actually, the A7, their executive liftback sedan, would fit the prompt of "luxury sports sedan" better, but 37 Down only has room for six As. || 6
|-
| 38-Down || A half-dozen eggs with reasonably firm yolks || Eggs can be [https://www.saudereggs.com/blog/egg-grading-system/ "graded on a variety of aspects"], with grades B, A, or AA. Eggs with a reasonably firm yolk are graded A, so having half a dozen of them gives you AAAAAA eggs. || 6
|-
| 39-Down || 2-2-2-2-2-2 on a multitap phone keypad || A "{{w|multi-tap|multitap keyboard}}" is a text entry system for mobile phones. Most numbers are associated with three letters, and tapping the same number multiple times in rapid succession selects the 1st, 2nd, or 3rd number. 2 is "a", 22 is "b", 222 is "c", 3 is "d", etc. 2-2-2-2-2-2 translates to "aaaaaa". || 6
|-
| 40-Down || .- .- .- .- .- .- || .- is Morse Code for A. It reads out as AAAAAA. || 6
|-
| 42-Down || Rating for China’s best tourist attractions || China's Ministry of Culture and Tourism provides ratings for many tourist attractions in China on a scale from A to AAAAA, with AAAAA being the best. Examples of well-known tourist attractions with the AAAAA rating include the Forbidden City, sections of the Great Wall of China, and the Terracotta Army. || 5
|-
| 43-Down || Standard drumstick size || 5A is a common, middle-range size for drumsticks (the sticks used to play drums, not the drumsticks that get eaten). Here, it's written as AAAAA. || 5
|-
| 45-Down || “The rain/in Spain/falls main-/ly on the plain” rhyme scheme || An AAAA rhyme scheme means each of the four lines ends with the same sound. || 4

==Transcript==
:[A square 15x15 crossword puzzle is shown. Only 21 of the 225 squares are black. The black squares are in a pattern that are 180 degree rotationally symmetrical. Three black squares down from the 11th column and similarly three black squares up from the 5th column. Three black squares out from the right in row 7 and then two more black squares diagonally up from the end. Similarly three black squares out from the left in row 9 with two more black squares diagonally down from the end. A single black square is three above the first black square on the diagonal going down to the right and similarly there is a black square three under the first of the diagonal squares going down to the left. (Row 6 column 12 and Row 10 column 4). Finally there are three black squares on a diagonal crossing over the central point by going up from the left through the central point (Row 8 column 8). There are numbers at the top of every column (except the one that is a black square) and similarly at the left edge of all rows (except the one that is a black square). There are also numbers at the bottom of every black segment (except the one that reaches the bottom) and all rows after black segments except the one that reaches the right edge. In total all numbers from 1 to 51 is written. They are written in reading order from 1 to 51.]

==Trivia==
*This comic got a [[Header_text#A_Crossword_Puzzle|comic-specific header text]] after the first day it was up.
**This was because one of the comics Randall lists as one of those he enjoys, [https://www.buttersafe.com/ Buttersafe], had already posted a similar comic back in 2011: [https://www.buttersafe.com/2011/02/17/crosswords/ Crosswords]. 
**Randall had forgotten this, but now pays tribute to this, stating that he must have been accidentally inspired by that comic.
*[[User:Elfakyn|Elfakyn]] posted a link to a picture of the solved crossword puzzle in the [[Talk:2957:_A_Crossword_Puzzle#Solved_puzzle_picture|coments]] and allowed it to be included here:
