How we judge. People play every entry.
Fun
Whether it makes you want one more go.
Originality
An idea we have not played before, or a familiar one taken somewhere new.
Polish
Whether it loads, works and feels finished for seven days of work.
Who judges
The Twigpine team plays every eligible entry after the deadline and picks one winner.
When
Within a week of the deadline. We email the winner first, then announce it on X and on this page.
The rules. Short, and the same for everyone.
- Build it during the round. Work started before the round opened does not count, and your source history should show when it was made.
- Make it playable from a link. Anyone should be able to open it in a browser, with nothing to install and no account to make.
- Use your own work, or assets you have the right to use. No characters, logos or brands that belong to someone else.
- One entry per builder per round. To change your entry, submit it again before the deadline; we judge the latest one.
- Teams are welcome. Name one wallet, and the prize goes to it.
- The Twigpine team judges every eligible entry, and its decision is final. Members of the team cannot enter.
- The winner is paid $1,000 in USDC on Base, to the wallet in the entry, after we confirm the win. We may ask you to show you control that wallet and the X account you entered with.
- Entries are private until we review them. We may show reviewed entries on this page and on X, with your name and links.
- You keep every right to what you make.
- You are responsible for any taxes on the prize. An entry is void where a contest like this is not allowed.
Questions.
- Is there a fee to enter?
- No. Entering is free.
- Do I have to use Twigpine to build it?
- No. Any engine, any language, any stack, as long as it runs in a browser from a link.
- Can I use AI to build it?
- Yes. Use whatever tools you like. Judging looks at what you made, not how you typed it.
- How do I share my build?
- Post it on X and tag @twigpine so we can share it. It is not a condition of entry, and we never ask you to follow or repost anything to enter.
- When do Memes and DeFi open?
- Memes is the November round and DeFi the December round. Each round's dates and brief go up on this page and on X before it opens.
- When is the winner announced?
- Within a week of the deadline, on X and on this page. We email the winner first.
Submit your game. Before Fri 16 Oct, 23:59 UTC.
Eight fields, two of them optional. We read every entry; nothing appears publicly until we have reviewed it.
