# Monthly Topic Challenges: Topic Suggestions

Fortnightly Topic Challenges are all water under the bridge now, so we will do something completely different.

What to Do:

If you have an idea for a tag or a theme of any kind to use as a topic challenge, post it as an answer below. (Do note, you can propose anything, not only a tag). Each answer should start with the title of the topic in a markdown heading (## Title ##). Only one suggestion per answer, please. Here is a list of all tags, to help.

At the start of each month, the highest-voted answer to this post will be selected as that month's topic. Starting from today, users can propose their themes or topics. The selected answer will then be deleted to reduce clutter in the list.

After the selection, a new question will automatically be created in this format. An answer will then be posted to that question with links to all the posts in the featured topic in the fortnight.

We'll again keep a list of all the topics.

Happy Puzzling!

The first MTC will start on January 1st, 2022. In the meanwhile, topics will be gathered and voted on.

## Restricted Title: xkcd 1xxx

See this FTC, which dealt with the first 1000 xkcd comics

Usually the title is decided upon later in the puzzle creation process, chosen to be fitting and often to provide a hint/reference. Here we're going to go the other way.

Below is a list of the titles for xkcd comics 1000-1999, filtered down to those titles which are a valid Stack Exchange question title (≥ 15 characters). Pick any of the 300 remaining titles and use it as-is (preserving case, part numbers, parenthesised words, etc.) — this will be the title of your new puzzle.

The title should make sense given the puzzle, whether that be through the puzzle's presentation, mechanics or answer. The more fitting, the better!

Don't be discouraged if you see that someone else has posted a puzzle with a title you had intended to use. If anything, it can be interesting to see what different approaches people take for the same title, should there be any collisions!

• Is this on for January?
– Amoz
Jan 1 at 15:09
• @Amoz If this isn't confirmed I might go ahead and post something off this list this month anyway. It may even be worth extending the first 'MTC' to cover Jan and Feb, as it seems we may need a little more publicity for this to be more widely known about and participated in.
– Stiv

• @Stiv Cool, I also already posted something off the list this month. Best publicity might be to simply start? Do we know where LR is? Or I can assist if needed.
– Amoz
Jan 8 at 3:01
• @Amoz We'd probably need a separate meta post for the month's challenge, in the same vein as previous Fortnightly Topic Challenges. 9 days in to the month now, it would be good if it could be started sooner rather than later. Is 7 upvotes sufficient interest to go? Will post in the chatroom too to gauge interest from regulars.

## On-and-onograms

Create a puzzle where the first step is a whose solution reveals further steps that must be taken. Crucially, the full puzzle is entirely self-contained within the nonogram and flavour text. (i.e. Not just using a nonogram as the first step in a long string of grid-deduction puzzles which require additional grids to be displayed in the post.)

Good examples from the past include these two puzzles by @jafe, one of which conceals a and the other a set of puzzles.

## pencil-and-paper-games

Throwing a purely tag-based one in...

Games meant to be played with a pencil and paper tend to be simple little time wasters. But that doesn't mean they can't be incorporated into puzzles in interesting ways! Their very simplicity means puzzles with them can still be easily understandable/accessible even if a little more complex.

This challenge is to create a puzzle deserving of the tag, or a related one like , even if using it would be a "spoiler" - so a which is edited into the list of challenge puzzles after a solve is perfectly fine. Puzzles would be about the pencil/paper games (strategy etc.), simply incorporate ideas/rules from them in some way (e.g. a Sudoku which has a Dots and Boxes variety rule), or involve such a game in some other significant part of the solve process.

## IQ Puzzle Parody

With frustrating regularity, PSE goes through periods of being overrun by requests for help with IQ questions found online or in interviews - most commonly of the type "Here's a bunch of boxes containing some kind of pattern - what image should go in the last box?" Often these questions are low-effort contributions to the site and highlight the very worst of 'guess what I'm thinking' type corporate exercises...

This is ripe for parody!

I propose a challenge where the user should strive to create a puzzle that resembles one of these IQ puzzles but actually disguises another puzzle or puzzle mechanism altogether. The multiple-box design could, for example, lend itself nicely to puzzles, s or puzzles with another clever component.

There's a world of possibilities here, and the opportunity for some fun at the expense of a widely disliked puzzle type...!

## Cross-non-words

The challenge here is to produce a crossword wherein some (or all) squares are filled not with typical English alphabet characters, but with something else altogether.

Such a crossword might contain no English alphabet characters at all (e.g. each square instead contains an image, a special character, a number, etc.) or each answer within it features at least one square containing one such alternative... Crucially, no words in the grid should appear fully spelled out with English alphabet characters.

Note: This is not merely a repeat of FTC #43: Variety Crossword Grids from November 2020 - here it is the content of the squares wherein the variety lies, as opposed to the structure of the grid...
