The WriteLight Group Flash Horror Challenge 2025

Welcome to our October flash horror challenge. Use the rules below, write short chills all month, and share your pieces on your site and social. This flash horror challenge is built to help you draft fast, finish often, and grow your audience.

Flash horror

A complete horror story told with extreme brevity, often under 1,000 words and sometimes as short as 300 to 750 words. See a concise flash fiction definition and word-count variants.

How the Flash Horror Challenge Works

Choose one of two tracks for October. Both are simple and sustainable.

• Daily Drip: Write one flash piece per day for 31 days. Keep drafts short. Publish at least three per week.
• Weekend Sprint: Write three pieces every Friday to Sunday. Publish at least one by Monday.

Use our prompts, remix them, or create your own. Keep the rules below to build speed, skill, and consistency.

Flash Horror Challenge Rules and Parameters

• Word count: 300 to 1,000 words per piece. This range aligns with common flash guidelines and keeps your drafting tight.
• Time cap: 30 minutes to draft, 20 minutes to revise, then publish or schedule.
• One core turn: Center each story on a single unsettling moment, choice, or reveal.
• Clarity over lore: Suggest a larger world. Avoid heavy backstory.
• Original work: Write only new stories this month. You keep all rights.
• Content guidance: Add a short content warning when needed. This respects readers and helps you build trust. See guidance on content warnings for authors.
• Share tag: Use #WriteLightFlashHorror on social. Link back to your site when you can.
• Craft focus: Prefer strong verbs, concrete images, and short sentences for tension.
• Submission to us: You may send links to your published pieces. We may feature favorites with credit and your permission.

Share Your Work and Get Featured

Publish on your own site first, then cross post excerpts to social with the tag above. To be considered for a feature on our blog, send the story link via our contact page. We will request permission before any feature and will link back to your site.

If you need a polished home for your stories, our author website setup option can help you get online quickly.

15 Flash Horror Prompts

1. You wake to a voicemail from yourself, recorded at 3:03 a.m., warning you not to open the bedroom door.
2. A town keeps its streetlights on all day. No one remembers why. The power company finally shuts them off.
3. The last book in the library will not let you stop reading. Every page shows your next mistake.
4. An apartment elevator takes you to a floor that is not on the panel. The doors will not close again.
5. You borrow a coat at a funeral. The pockets return items you lost years ago.
6. A pet camera catches your empty living room at night. Something off screen whispers your full name.
7. Every mirror in your house shows a slightly earlier version of today.
8. On a storm map, your street is labeled “evacuated.” You never got the alert.
9. A garage sale offers a jar labeled “10 minutes.” You buy it. You open it.
10. Neighbors leave October decorations up in July. Their pumpkins never rot.
11. A new rideshare driver refuses to stop at green lights. “They can see through those,” he says.
12. Your grandmother’s recipe card has a fourth ingredient written in another hand. It asks for blood type.
13. A lighthouse flashes in a code you almost understand. The beam stops on your window.
14. The forest trail sign counts down the number of hikers on the path. It goes negative.
15. You inherit a house key that fits nothing you own. It opens any locked memory.

Strategy: Write, Polish, Publish

Draft fast

• Set a 30 minute timer. Choose one sensory image and one fear. Draft toward a single choice or reveal.
• Favor crisp sentences and vivid nouns. For pacing ideas, see practical Horror Writers Association tips.

Revise once

• Cut soft openings. Start where something changes.
• Remove filler words. Check that the last line lands a consequence or new image.

Publish smart

• Post the story on your site. Add a one line teaser and a clear title.
• Share a pull quote to social with your link. Join conversations in existing flash fiction challenges to meet readers.
