 On May 9 , 2008 , after Rosetta @ home users suggested an interactive version of the distributed computing program , the Baker lab publicly released Foldit , an online protein structure prediction game based on the Rosetta platform . As of September 25 , 2008 , Foldit has over 59 @,@ 000 registered users . The game gives users a set of controls ( e.g. " shake " , " wiggle " , " rebuild " ) to manipulate the backbone and amino acid side chains of the target protein into more energetically favorable conformations . Users can work on solutions individually as " soloists " or collectively as " <unk> " , accruing points under either category as they improve their structure predictions . Users can also individually compete with other users through a " duel " feature , in which the player with the lowest energy structure after 20 moves wins .
