48 Secret Jam is a game jam where you make a game in 48 hours with a topic that won't be released untill the start of the jam.

How to win?

You don't have to be an artist or super musician to win. All you need is a great idea that is very fun to play and has something to do with the topic. A jury will be voting on your game. Each game will be played for 15 minutes by the jury, unless the game is very fun to play. So you could make a long storyline game, but I recommend not taking the risk.


the 48 Secret Jam will  be held 8 times each year. these are the next 8:

48  Secret Jam  2017 #1:  28 July / 30 July
48  Secret Jam  2017 #2:  8 september / 10 september
48  Secret Jam  2017 #3:  20 october / 22 october
48  Secret Jam  2017 #4:  8 december / 10 december
48  Secret Jam  2018 #5:  26 januari / 28 januari
48  Secret Jam  2018 #6:  9 March / 11 March
48  Secret Jam  2018 #7:  21 april / 23 april
48  Secret Jam  2018 #8:  7 june / 9 june

The Topic

The topic will be randomly chosen by the jury. When the jam starts, all the participants will receive an email that contains the topic.


  • you may not work on this with teams bigger then 2 persons
  • The game must be playable on windows, mac or Linux 
  • all the assets have to be made during the jam
  • when the jam starts and the topic is the same as that big game you recently made, you have to start  a new project. you may not resume an old project.

Of course none of the jurors can really check any of this. But please, to keep this contest fair, make sure you're following the rules. If you win by not using the rules, you didn't really win. Of course no one knows, but deep inside you know you didn't win.


The results are shown 3 days after the end of the jam. The winner will not win a big prize, but s/he will receive the honor of winning the 48 Secret Jam, beating all the other developers, and winning the first 48 Secret Jam.
