Curve Fever and Curve Fever 2 are the most fun multiplayer games to play together, on 1 keyboard! Not enough space on 1 keyboard, plug in a second one.


Curve Wall

Good morning Curve Fever community!


I've got something to show that I am really excited about, but first let me introduce myself: 

I'm Martijn Imhoff and I study Industrial Design at the University of Technology in Eindhoven. Since september 2013 I've also been an intern at Curve Fever, where I've been working on a cool project. This video explains it:



Let me know what you think!



Curve Fever tribunal

Take action against chat abusers

Go to

What is it?

The Tribunal is a site where players can report chat abusers. In the chat, there is a small link stating: “report player”. Everybody can click this link and make a report about someone saying bad things in the chat.

If you have played more than 100 games, you can are considered a judge and can review cases. Either it is a Pardon or a Punish, or you don’t know. Everybody who has played more than 100 games can become a judge! Because we appreciate your work as a judge, we give 5 coins per case that you have judged correctly. Thus it is also a nice way to earn some extra coins!


We believe that a game like Curve Fever should be nice to play for everybody. The internet is a great place to anonymously troll and offend others. But we don’t want this for our game, and that’s why we decided to take action. And thus we created the Tribunal.

So check it out at

Curve Fever is looking for languages!

Stay a gentleman

Dear players,

We want to let you know about a new policy in the forums. Well, actually it is not a new policy, but more an enforcement of a normal rule in life. It's a natural thing to do. We don't like the fact that there is so much swearing going on on the forums. Neither do we like the insulting texts to other users. And inside the game it is also bad. We want to start off by making the forum a polite place for everybody, and hope this politeness will eventually find its way into the game. So this means we will actively work on stopping any swearing or insulting behaviour.

Stay polite and respectful to each other! Be a Gentleman

Let's promote Curve Fever

Are you creative and do you have ideas on how to promote this game? Or maybe you know people who can help with promoting this game? Let us know! We are searching for ideas on how to get the game more known, both online as offline. All ideas are welcome, also the wild ones.

Curve Fever 2! Open BETA

Note, There might be many version changes to come in the coming weeks. Because there is version control, you should empty your caches (by pressing CTRL+F5) and restart your browser, if you get a version mismatch error.

Note, There are only few people playing the game right now. So if you want to play an online game, get your friends online, or say a time of start in your room name.

Note, When the game seems laggy, and your frames per second is smaller than 30fps (lower left corner), try to lower the quality of the flash movie by right clicking on the movie -> quality -> low quality. 

Open Beta CF2

Hi all,

We are currently finishing the game to be prepared for the open beta. This means that not all functionality will be there, but that it should be playable without too many bugs. In this thread you can give your feedback and suggestions on the open beta. We want to launch the open beta in the first week of October, and then it will be constantly online. Further there will be an update every week, including at least one new powerup.
