FAQ / Details

What is Core?

If I'm a newcomer to Core, where's the best place to start?

Check out our getting started page to quickly get up to speed and begin creating. For a more structured set of tutorials, follow along with our free courses at Core Academy.

Can I make unique looking art in Core?

Yup! From high fantasy to dark wonderlands to modern military, we've got assets to match the mood - and thousands of primitives and materials to kitbash your own from scratch as well! Our art director's blog post describes the ideology behind it all, for those who are curious.

What do you mean by art-focused jam?

We'll primarily be judging the submissions by their aesthetic values, but limited gameplay will be help elevate submissions. Note that we provide plenty of tools to make it easy! See our 'frameworks' (create --> new project) for full sets of game logic you can drag and drop into your map.

Can I use community content?

As always, yes, it is encouraged! Please do give credit (in your game descriptions) to pay it forward.

Are there any submission specifications?

To enter, you must fill out the form below. Feel free to ask any questions in the relevant Discord channel (e.g. to confirm your entry was received successfully).

We encourage also including WIP shots, and anything else that helps show off the process, but this isn't mandated.

Can we use existing games?

As long as it fits the theme/category, yup! We do balance the judging based on what new/unique content was made, so existing games don't have an unfair advantage, but we want to encourage people to not 'reinvent the wheel' and to keep improving existing games - doing so helps you get up and running as fast as possible (important in a time-dependent jam), and also helps make a more fully-featured game you can really be proud of!

How are entries judged?

We will take into account any adherence to the theme and category, then will judge based on the aesthetics (50%), functionality (10%), and our overall impression (40%). Note that the interpretation of these is up to the judges' discretion, and they have the final say.

Can I submit multiple entries?

Sure, but they must be unique entries! You can not submit the same entry in multiple categories.

Can I update my entry after submitting?

Yes. But beware, judges will only be reviewing your entry once, so if you push a last-minute update and it has a game-breaking bug that will be reflected in your score. Because of this, it is heavily recommended to stick to the deadline. To keep things as fair as possible, judges will be playing the submitted games in a random order.

Can I work with a team?

Yes, and please do! For profile pics, please put all your collaborators' names (up to 5) and their credits in the game description for them to get this endowment too. Note that if your team wins, distribution of the prizing must be handled by yourselves (i.e. we'll give the prizing to the submitter, then they can allocate to team members).

What if I'm under 18?

Ask your parent or guardian to submit your entry on your behalf. They will receive the prize and then can pass it on to you at their discretion.

How are winners paid?

We use Tipalti to pay winners in their local currency. Winners will be contacted via email with the details. Please open a support ticket if you have questions regarding payment.
