Every entry is built during the jam.

Building is open. Make your entry as a game, story, or video on RUN, publish it to public, then enter it with Enter the jam before November 2 at noon PT. Games are ranked by community votes, open from October 15 through November 6, and the RUN team picks its own favorites across every format, so publish early, share your entry, and give people more time to vote for it. Updates never reset your entry.

02 / How to enter

Build it, publish it, enter it.

The theme is Monster Mash. Build a game, story, or video about monsters on RUN, publish it to public, then enter it with the Enter the jam form in Creator Hub before November 2 at noon PT. Games compete for Game Votes and the Game Editor's Picks; stories and videos compete for Story & Video Votes; every entry is eligible for all four Special Categories.

01

Pick your tool

Use Game Studio, Story Studio, or Video Studio right in your browser, or build on your computer with the CLI in Claude, Cursor, or ChatGPT with Codex.

02

Build your monster

Start a new project now; work started before October 8 at noon PT doesn't count. You have until November 2 at noon PT: solo or with friends, no team-size cap.

03

Publish and enter

Publish your entry to public, then open Creator Hub, click Enter the jam on the October Jam card, and pick it. Do it before November 2 at noon PT; publishing alone doesn't enter you. Voting opens October 15 and runs through November 6, so the earlier you publish, the longer your entry has to collect votes. Keep refining all jam; updates never reset your entry.

03 / The jam is live

25 days on the clock. Here's where to put your energy.

25 days to build, with voting open from October 15 through November 6 and the RUN team picking its favorites. These three moves matter most while the jam is on.

Publish the moment it clicks

Voting is open from October 15, so every day you're public is another day you can collect votes. Publish to private to playtest, flip to public as soon as your entry lands, and keep refining all jam; updates never reset your entry or its votes.

Share to climb

Votes count from October 15 all the way through November 6, so everyone you reach now can vote for you today and bring others tomorrow. Grab your entry's share link and post it in the Discord, Reddit, X, your group chat.

Watch the leaderboard

Standings go live when voting opens October 15, then update as votes come in. Bookmark it, see where your entry lands, and keep refining to climb.

04 / About

A 25-day jam. The theme is Monster Mash.

October Jam is a creator jam on RUN, and the theme is Monster Mash: monsters, creatures, and the things that go bump. Make them the hero, the villain, the roommate, or the whole cast.

Build your entry in Game Studio, Story Studio, Video Studio, or the Adventure Studio. You have until November 2 at noon PT to build it, publish it to public, and enter it through the Enter the jam form in Creator Hub. Games are ranked by community votes, open October 15 through November 6, and the RUN team picks its own favorites across every format, so publish early and build something people want to champion.

06 / Theme & rules

What counts as an entry

  • To enter: build an original entry on RUN during the jam, publish it to public, and submit it through the Enter the jam form in Creator Hub before November 2 at noon PT. Publishing alone does not enter a project. Games can be built in Game Studio, with the rundot CLI, or in the Adventure Studio (all count as a game entry); stories in Story Studio; videos in Video Studio. Only work created and first published publicly during the jam can be entered.
  • Your entry must fit the theme, which drops October 8. Full eligibility details land with the theme reveal.
  • Building opens October 8 at noon PT. Anything started before then is disqualified. Original ideas only: no 1:1 clones, no copyrighted character names or art.
  • Solo or team, no team-size cap, but every team member must be credited.
  • Submissions close Monday November 2 at noon PT. Late means disqualified.
  • Scoring: winners in Game Votes and Story & Video Votes are decided by community votes, which can be cast from October 15 at noon PT through November 6 at noon PT. Publishing earlier gives your entry more of that window to collect votes, so publish as soon as it's ready and keep refining; updates never reset your entry or its votes. The 5 Game Editor's Picks are chosen by the RUN team from Game entries. Winners are announced live after judging closes November 6 at noon PT.
  • Story Studio and Video Studio entries compete on their own 3-place Story & Video Votes leaderboard, ranked by community votes on the same October 15 to November 6 window. Games compete for Game Votes and the 5 Game Editor's Picks.
  • On top of all of that, 4 Special Categories (Most Sticky, Best Monetization, Best Social Features, and Best Use of Theme) are chosen by the RUN team and are format-agnostic: every published, on-theme entry is eligible for all four, whether it's a game, a story, or a video. These are additional, so winning one doesn't affect your standing anywhere else.

FAQ

Common questions

Is this just for games?

No. Games are the main track: build a playable game in Game Studio, the Adventure Studio, or with the CLI, and it competes on the Game Votes leaderboard and for the 5 Game Editor's Picks. Story Studio and Video Studio entries are welcome too, and compete on their own Story & Video Votes leaderboard, ranked by community votes the same way as the Game track. Whatever format you build in, your entry is also eligible for all four Special Categories. You can enter as many projects as you want through Enter the jam; each one competes on its own.

Can I start building before October 8?

Practice and plan all you like, but your entry must be built during the jam, which opens October 8 at noon PT, the same moment the theme drops. Anything started earlier won't count. Use the wait to get comfortable in Game Studio, Story Studio, Video Studio, or the Adventure Studio with a throwaway project.

How does my entry get on the leaderboard?

Enter it yourself. Once your game is public and approved, open Creator Hub, click Enter the jam on the October Jam card, and pick it. It shows on the leaderboard once it's entered. Only work created and first published publicly during the jam can be entered. If Enter the jam says "Nothing to enter yet," check that your project was started after October 8 at noon PT and is published to public. Games are ranked by community votes, which can be cast from October 15 through November 6, so publishing earlier gives your entry more of that window to collect votes. Publish early, get feedback, and keep refining; updates never reset your entry or its votes.

What counts as a qualifying entry?

For Game Votes and the Game Editor's Picks: any original game built during the jam that fits the theme, once it's revealed, built in Game Studio, the Adventure Studio, or with the CLI, published to public, and entered through Enter the jam. For Story & Video Votes: any original Story Studio or Video Studio entry made during the jam, published to public, and entered through Enter the jam before submissions close. For the Special Categories: any of the above. All four are open to every format. Every entry has to fit the theme, which is announced when the jam opens on October 8 at noon PT.

Does an Adventure Studio project count as a game?

Yes. An Adventure Studio build is a game entry: it competes in the Game track, on the same leaderboard as games built in Game Studio or with the CLI. Whether you use Game Studio, the CLI, or the Adventure Studio, it all counts as a game. Just keep it original, on-theme, published to public, and entered through Enter the jam before submissions close.

What are the Editor's Picks?

Awards chosen by the RUN team rather than by votes: 5 Game Editor's Picks ($15,000 down to $800), drawn from Game entries. They're separate from the vote-based ranking, so a game can place on Game Votes and still take an Editor's Pick.

What are the Special Categories?

Four extra $500 awards on top of everything else, chosen by the RUN team. They're format-agnostic: a game, a story, or a video can win any of them. Most Sticky goes to the entry with the best reason to come back tomorrow: a loop, a streak, a cliffhanger, anything that earns a second session. Best Monetization goes to the entry whose purchase or upgrade feels genuinely worth it rather than a wall in your way. Best Social Features goes to the best reason to pull someone else in. Best Use of Theme goes to the entry that does the most with the theme once it's revealed. These stack with everything else, so taking one doesn't affect your standing on any leaderboard or in the Editor's Picks.

I published. Now what?

Now you gather votes. Voting is open from October 15 through November 6, so once it opens, everyone who plays and loves your entry can vote for it right away. Grab your entry's share link and post it everywhere it fits: the jam Discord channel, Reddit, X, your group chat. Early fans become votes that count toward your score right away. Point people at the leaderboard too. Watching the standings move is half the fun, and it pulls in more attention. Keep refining. You can keep improving your entry until submissions close; updates never reset your votes, and a sharper idea wins more of them.

Do I need to know how to code?

For games: no. Game Studio in your browser or an AI desktop app on your computer let you build a game by describing it in plain English. The AI writes the code; you steer and test. Story Studio and Video Studio work the same way: describe what you want and the AI builds it.

Can I work with a team?

Yes. Solo or team, no size cap. Just credit every member on your entry.

Will I be charged to enter or build?

No. You pay $0 to enter and build. AI generation has a real cost to RUN, so we use credits to track usage. We'll email you a promo code for 100,000 free credits when the jam opens. More ways to earn free credits turn up as the jam goes on, and we announce them in the Discord.

When does it all end?

Pencils down Monday, November 2 at noon PT. Judging runs through November 6 at noon PT, and winners are announced live after it closes.
