JRPG Crypto Browser Game Jam

# Welcome to the JRPG Crypto Browser Game Jam! You've got one weekend to make a crypto game anyone can play in a browser. Let's see what you come up with. ## What is the JRPG Crypto Browser Game Jam? It's a weekend online game jam. It kicks off Friday, November 20 at 09:00 UTC and ends Sunday, November 22 at 21:59 UTC. That's about 61 hours to build a crypto game that anyone can play in a web browser. It's free to enter. Go solo or bring a team of any size. ## Prizes? None! This jam offers no cash prizes, tokens, merchandise, or other rewards of any kind. It's just for fun. JRPG staff will rank the top three entries as 1st, 2nd, and 3rd place. The rankings are titles only. --- ## What do we do at this jam? Make a crypto game that runs in a browser! ### Your game must: - **Run in a browser.** Players open a link and play. No downloads, installers, or app stores. Games that can also be embedded in another web page are welcome. - **Have a crypto element that matters.** Wallets, on-chain items, smart contracts, on-chain randomness, a game about crypto culture: it's up to you. The crypto part should change how the game plays. - **Be playable without spending real money.** Judges will play on test networks or without a wallet, and they won't buy anything. Your game can support a main network too, but it has to be fully playable on a test network or with no wallet at all. Any engine and any blockchain are welcome. --- ## How do I sign up and participate? 1. Click **Register** on this page and answer the sign-up questions. 2. Looking for teammates? Use the **Join a Team** tab. Solo entries are welcome too. 3. Plan all you want before Friday, but don't write game code or make game content until the jam starts. 4. Build your game between Friday, November 20 at 09:00 UTC and Sunday, November 22 at 21:59 UTC. 5. Host the playable version on your own site, GitHub Pages, our JRPG website or any other web host. 6. Create a BUIDL and submit it to this hackathon before the deadline. --- ## Ground rules 1. **Build it during the jam.** All game code and original content must be made between the start and the deadline. Existing engines, frameworks, libraries, smart contract libraries, and templates are fine. 2. **Check your asset licenses.** Pre-made assets are allowed, but some marketplace licenses forbid using their assets in anything that uses blockchain technology. List every third-party asset and its license in your submission. 3. **AI tools are allowed.** Tell us what you used them for. 4. **One entry per team.** Each person can be on one team only. 5. **No gambling.** Not with assets that have real-world value that is. 6. **Keep players safe.** Never ask for a seed phrase or private key. Don't request token approvals or signatures that touch real funds. Entries that do will be disqualified. 7. **Freeze your game at the deadline.** Don't update the playable version after submissions close, except to bring it back online if your hosting goes down. We'll check commit history. 8. **Keep it online until results are out.** Your playable link has to work until November 30th. 9. **Keep it respectful.** No hateful, harassing, or sexually explicit content. The DoraHacks Code of Conduct applies. Entries that break these rules or don't fit the theme won't be ranked. --- ## Judging rubric JRPG staff will play every entry from November 23 to 27 and score it on four criteria. We'll announce results by Monday, November 30th. ### Criteria & Points **Fun** (max 35 points): Is it fun to play, and does it make you want another round? **Crypto integration** (max 25 points): Does the crypto element change how the game plays, rather than sit on top of it? **Creativity** (max 20 points): Does it try something we haven't seen in crypto games before? **Polish** (max 20 points): Does it load quickly, explain itself, run without bugs, and work for players who have never used a wallet? ## Submission requirements: **DEADLINE: Sunday, November 22, 21:59 UTC. Late submissions won't be accepted.** - Link to the playable browser version. - Public source code repository link. - A short description of the game and how to play. - How the crypto part works, which network(s) it uses, and how judges should set up a wallet if one is needed. - Every third-party asset you used and its license. - What you used AI tools for, if anything. - Optional: a short gameplay video. It helps us if your game ever fails to load. --- ## Who can enter? Anyone who meets DoraHacks's age rules: you must be at least 13 (16 in the UK and EU). If you're under 18, you need a parent's or guardian's permission to take part. ## Your game stays yours You keep ownership of everything you make. By submitting, you allow JRPG to play, stream, screenshot, and write about your game in its articles, videos, and podcast, with credit to your team. Submitting a BUIDL also falls under the DoraHacks Terms of Use, including their Contribution License.
