Foldit is a citizen science video game in which players tackle a variety of complex biochemistry puzzles. Here, we describe a new series of puzzles in which Foldit players improve the accuracy of the public repository of experimental protein structure models, the Protein Data Bank (PDB). These efforts highlight the continued need for the engagement of the lay population in science.
