What this page is

This page quotes r/mathpuzzles's rules as ThreadFox read them on 2026-10-12. The quoted text is the community's; the verdict above is our reading of it. Conditions often decide whether a post fits (a required thread, flair, posting day, account age or karma), and r/mathpuzzles's current rules on Reddit always win over this page.

Free, for a specific product: a researched Reddit plan by email (communities whose rules fit your post, quoted and dated), or ThreadFox Lite, read-only tools an AI assistant can use to read a community's current rules itself, through your own Chrome (Claude Code: claude mcp add threadfox-lite -- uvx threadfox-lite). For an assistant that also writes and posts within each community's rules, the ThreadFox kit is $49 once.

Want to post here? Get ThreadFox ($49): your AI (Claude Desktop, Claude Code or Codex) reads a community's current rules, writes one post that fits and posts once from your own Chrome. No Claude? We'll post for you ($49 per 30-day campaign). Free: a Reddit launch plan for your product, ThreadFox Lite or the posting checklist by email.

This is a subreddit dedicated to mathematical puzzles and challenges.

All 3 rules of r/mathpuzzles
  1. No links to other games
    No links to other games or websites with puzzles. The puzzle should be entirely contained in the post, though imgur and the like are allowed for images, videos, etc., as long as it's not a website dedicated to puzzles
  2. No puzzles that are guessing the next number in a sequence, a grid, or any other N-dimensional space
    If your puzzle solely relies on finding a specific pattern in a sequence or collection of numbers, it does not belong here and will be removed
  3. No puzzles that are guessing the next shape in a series of shapes
    If it's totally open to interpretation, or there's ways to support multiple answers, it does not belong here.

What the written rules don't show

  • Unpublished minimums. Many communities remove posts from new or low-karma accounts through AutoModerator settings that are not on the rules page, often before a moderator sees them.
  • Reddit's own filters. Reddit's site-wide spam filters can remove posts from accounts that mostly share links to their own site, in any community.
  • The community's norms. Many communities see themselves as peers, not an audience: post where you already take part, and make the post worth reading without the link.

Let your AI read the rules before it posts.

ThreadFox reads a community's current rules, writes a post that fits them, posts once with Reddit's Brand affiliate tag and checks it stayed up. The free ThreadFox Lite reads rules too.
