Foldit is an online game in which humans try to solve one of the hardest computational problems in biology: protein folding. You don't need to know anything about biology to play the game, although a little background will help. Most Foldit player are not biologists. Read about The Science Behind Foldit.
In response to the global pandemic, Foldit has been coronavirus puzzles of various types.
The puzzles so far have involved designing binder proteins to attach to the coronavirus spike protein, designing anti-inflammatory proteins to calm the "cytokine storm" sometimes triggered by the virus, and predicting the 3D structure of proteins the virus is believed to manufacture, with names like NSP2, NSP6, and ORF3a.
There will probably be coronavirus puzzles running for the foreseeable future, see the official list of puzzles for details.
See the Coronavirus FAQ for general information about the Foldit coronavirus puzzles.
Visit the fold.it, the official Foldit site to download the game and get started. Foldit runs on Windows, Mac, and 64-bit Linux. See Download-Install-Troubleshoot for install instructions. Use the feedback page if you're having trouble getting the game installed. If you're seeing "error contacting server" messages, update this feedback with details.
New: the video QUICK Foldit Tutorial Walkthrough from S0ckrates shows the fast path through the intro puzzles.
See Get Started Playing Foldit for more.
See Foldit Status for any issues affecting the game.
Note: this list gets updated weekly after the current revisiting puzzle expires. See the official list of puzzles for the most current puzzle info.
- Puzzle 1855: Y1 Receptor ligand design, expires 1 July 2020.
- Puzzle 1856: Coronavirus Binder Design: Round 12, expires 2 July 2020.
- Puzzle 1857: Refinement Puzzle: R1029, expires 3 July 2020.
- As always, there are Intro Puzzles to get started, and then Beginner Puzzles which allow players to hone their skills.
- Slow reaction! After a flurry of software updates, the first reaction design puzzle - Puzzle 1855: Y1 Receptor ligand design - is out. The wiki needs to catch up on how reaction design works, which is different than how previous small molecule design puzzles worked. There's also a new look for intro puzzles, including a new reaction design intro. The new system allows a shorter path through the intros. The details of the individual intros haven't changed much. Hang on while the wiki lurches forward, a little behind as usual.
- No revisiting: Puzzle 1857: Refinement Puzzle: R1029 has temporarily interrupted the revisiting puzzles. The puzzle presents a CASP "solution" to a protein, which is pretty clearly a decoy. Players once again get a chance to show up the scientists by finding a better solution.
- More lab work: two sets of player designs from coronavirus puzzles are headed to the wet lab. See the blog posts Anti-inflammatory designs queued for testing! and Coronavirus binder designs queued for testing! for details.
- Flying down to Rio: Portuguese translation describes how to install socramdm's new Brazilian Portuguese translation. Also Foldit Translations and Translating Foldit have been revised, and there are new pages Set language and List of translations.
- Discord comes to Foldit: A new Discord server gives players a new spot to hang out. Discord is oriented toward online gaming, and offers many features not found in IRC chat. In addition to basic text chat, Discord has voice chat and even screen sharing options. Discord has apps for Windows, macOS, Android, and iOS, and also offers web access. Discord users can be connected on multiple platforms at the same time. Messages on Discord persist, so offline users can catch up later.
- Chillin': the Foldit Cryo-EM paper has been published in PLOS Biology. The Foldit blog makes you scroll down before announcing Foldit players take gold!. Once again, Foldit players beat actual scientists. The paper's supplement (docx format) contains commentary from several Foldit players on how they did it.
- Free proteins: the four known solved Foldit designs seen in the Foldit protein design paper are now available in all their 3D glory in the PDB.
- Nurture versus Nature: De novo protein design by citizen scientists, describing the results of Foldit design puzzles, was published in Nature 5 June 2019. Five Foldit players are listed as named authors, along with "Foldit Players". A longer list of players appears in the "Supplementary information" section. See the Foldit blog post about the paper. Congratulations to lead author Brian Koepnick!
- Closely contested: Foldit now lets you bring your own protein with custom contests. This feature has been frequently requested for classroom puzzles. We'll have more about it on the wiki soon, in the mean time read the paper describing how it works.
- Naming names: a number of Foldit players are listed as authors (using their real names) on an article just published in Nature Scientific Reports. See Interesting Articles (under "contribution of Foldit players to scientific results") for a complete list and a link to the paper.
