Trijam 333 will take place over 3 weeks, but as usual, you have the 3 hour challenge (9h total). This is Jam 2 in a 3 Jam series. Each following week you will have a chance to improve your game, based on the feedback from our community! Each week there will be a theme that we vote for as usual and we’ll pick winners as usual. The only difference is that you will be working on a game for 3 weeks. That said, anyone can jump in later as well, they can catch up if they had been busy. As always, the goal is to practice and improve your skills. The scope can be bigger, you’ll get more feedback! Stay tuned for themes you’ll have to mix in for Trijam 333! Part 2 and Trijam 333! Part 3. 


Trijam is a weekly game jam where your goal is to make something playable (and fun!) in just 3 hours, and our history shows that it’s more than just possible! Here’s a short video explaining how it works if you don’t feel like reading the page.


The rules are simple: try your best to make the game in 3 hours, but even if you can’t - still submit it, you are allowed to go overtime! However, only games developed in 3 hours or under are eligible to get the 1st place. The time only counts for building your game, that is, any coding, making sound effects/music, art, and other assets. Writing a design doc, coming up with ideas, compiling your game, or making the itch.io page for it does not!

You can use the official unofficial Trijam timer/study music video to time your 3 hours! Pause when you take a break, continue when you come back!

You can split your time into however many chunks you want, too - work on it for 3 hours straight, or for one hour each session, or any other way you may prefer!

Have a team? Great! Everyone on your team gets their own 3 hours! One person may focus on one part, another on another, and so on. There are no restrictions on team sizes, so invite your friends!

Using pre-made assets is no problem, just make sure that you have the necessary rights to use them, and attribute them in your game’s description properly.

Also, if possible, prefer web/HTML5 builds of your games so more people can play them!

Every week, the community (that’s you!) votes on the theme for the jam out of 5 themes we arbitrarily choose. We sometimes take theme suggestions too! Join our Discord (see below) to take part in that. You are free to interpret every theme in any way.

The theme gets announced every Friday, along with the next jam’s page on our Discord.

The jam takes place every weekend from Friday 9 AM UTC - Monday 10 AM UTC, so there is plenty of time for you to take part!

After the jam is over, the voting period starts and ends on Wednesday 7 PM UTC.

The games are rated in a 5 star system in the following categories

You can vote however you like, as long as your votes are consistent across all games. Whether 4/5 for graphics means “it’s nice” or “it’s not that nice” to you, make sure to apply that to all games equally! Thanks!

Every week after the jam has ended, we have two streamers who will play your games and give feedback. They are:

Rocknight Studios (Twitch) will livestream your games on Wednesday. They will need either a Linux or a web/HTML5 build of your game.

Paanch Tanmatra Studio (YouTube) will livestream your games. They can also play Windows games.

Use hashtag #Trijam on Twitter during the jam and we'd love to check out your games and retweet @TrijamGJ.

To get notifications on these livestreams, join our Discord where you can chat with fellow jammers!

Here’s a history of previous winners!
