☑️ Submitting your entry

To submit your Game Jam entry, please ensure that you complete the following two steps:

  1. Upload your Game Jam entry to the Drafts Gallery in the Game Maker. Please follow the directions in the GIF below and make sure to use the paper airplane and not the globe when sharing.

2. Fill out the SUBMISSION FORM.

PLEASE NOTE: It is a good idea to go through the submission form before you start creating your game. This ensures that you are best prepared for everything that you need in order to submit your entry.

TEST YOUR GAME: It is advised that you take some time to test your game before submitting. We strongly recommend that you also upload your game to the Drafts Gallery and test it there, too, as new issues sometimes arise, which may cause you to have to spend time on fixing and adjusting. We do not allow extra time for bug fixing after the deadline.

Judges reserve the right to remove any entries that do not follow the above rules. Entries perceived as spam will likewise be removed at their discretion.

Judges & Voting

Voting consists of two phases and is done primarily by The Sandbox staff in collaboration with The Council.

Game Jams done in collaboration with The Sandbox’s partners may also include partner judges who will vote in phase 2.

Games are judged based on five categories, amounting to a maximum of 22 points per judge. Voting categories consist of the following:

Overall Creative Idea (max 5)

  • Is your idea good?
  • Is your idea unique?
  • How well is the game following the theme?

Level Design (max 5)

  • Does the game flow well so it is easy to find your way?
  • Is the player able to skip past or enter areas that they shouldn’t be able to?
  • Is the terraforming visually appealing / coherent with your game?
  • Is the artistic direction appealing and coherent with your game?

Game Design (max 5)

  • Is the logic well designed, so the game is fun and engaging to play?
  • Have you used interesting and/or innovative mechanics?
  • Does the player encounter bugs, issues, or poor design choices that negatively influences player experience?
  • Is the progression curve too easy, just right, or too challenging?

Playability (max 5)

  • Is the gameplay intuitive?
  • Is the game immersive?
  • Does the player encounter issues that disturb the player experience?
  • Does the game offer good replayability?*

Wow Factor (max 2)

  • Does the game have outstanding artistic direction?
  • Does the game include good unique mechanics/features?
  • Does the game have an outstanding atmosphere/immersion?

*Replayability is taken into consideration where it makes sense. We are aware that some games and genres are naturally more replayable than others. Regardless, it is always a good idea to consider ways that your game may encourage players to play it again.

Who can join the Game Jams?

Anyone can join in on the fun for a chance at our amazing prizes! All you need is a Sandbox account with a linked wallet, a good idea, and a competitive spirit.

Don’t have an account? Go here for a guide on account creation.

Are teams and studios allowed?

Yes! You may work independently or in teams of up to 4 people. Rewards will be split among all wallets supplied in the submission form.

If you want to make connections and find other creators to work with, we recommend that you visit our Discord.

What are my chances as a solo creator vs. teams/studios?

Do not feel discouraged as a solo creator. We have seen plenty of solo creators ranking in the Top 10 in our Game Jams.

💪 TIP: Stay organized! Carefully plan what you need to do and when. Consider the most important aspects to creating a good game. You may choose to spend less time creating assets, as this is time consuming work which has some but limited influence on your score. You can make great games using basic assets and just a few important assets created by yourself. You can also browse the Marketplace for assets to buy.

Do I need to create a lot of high quality assets in VoxEdit to win?

No, you do not. Artistic direction, which includes assets, is taken into account in your score, but there are many other factors taken into account.

If you have limited time, focus on creating an engaging game with good logic, fun mechanics, a good flow, and perhaps a good narrative. You can create just the most important assets yourself and still make a visually appealing game with that and the Game Maker’s basic assets.

I discovered a bug after the submission deadline — can I fix it?

No, we do not allow any updates after the deadline. We expect that you plan and organize yourself so you have enough time to test your game and fix potential bugs before submitting your entry.

I made an amazing game for a Game Jam, but it did not win — why?

Please read all the rules and voting criteria carefully. There are many aspects that go into creating a good game. Maybe you invented an incredible mechanic, amazing assets, or a thoughtful narrative, but your game fell flat because it did not feel engaging, immersive, or fun to play.

Please note that all judges from The Sandbox and The Council who vote on your games are experienced in using the Game Maker and know what makes a good game and what does not. If your game did not rank, something was missing from the overall experience.

When you submit your game through the submission form, you are also able to opt for feedback from The Council. If you do, The Council will contact you when results are out to give you feedback on your game.

Good luck to all participants!
