Paper uncovers power of Foldit gamers' strategies
Date:11/7/2011

f Foldit and the creative director of the Center for Game Science,

Researchers put 721 gamers under a magnifying glass during a three-month period, and studied their play in detail. These players used tools for creating, editing, sharing and rating game-playing recipes within the Foldit game. One of these, dubbed Blue Fuse, was the most popular recipe used in the game.

In the game, puzzlers must build proteins that show certain characteristics including using the least energy. This is called "energy optimization." Blue Fuse scored well in designing proteins for this requirement. In a surprising turn, Blue Fuse also bore a striking resemblance to a scientist-built yet-unpublished algorithm from the Baker lab that they named "Fast Relax."

People playing the game, including the author of Blue Fuse who plays under the Foldit username Vertex, were surprisingly willing to share their recipes. Sharing, which may seem odd for competitive people, proved quite common among Foldit players. "I shared BF fully because Foldit is so much more than a game the competition is serious and fierce, but we are also trying to improve the understanding of huge biological proteins. We collaborate and compete at the same time," Vertex wrote. He pointed out that he built Blue Fuse partly borrowing from the elegance of another recipe by a different gamer, "Acid Tweeker."

"Blue Fuse spawned from Acid Tweekerand now has many children of its own. To 'Fuze' has even become a Foldit verb. And the next flash of inspiration can come from literally anyone," he wrote via email.

While researchers hope to find ways to almost automate human intuition, Khatib pointed out that this study demonstrates the remarkably flexible nature of the gamer intelligence.

"Foldit players employ recipes only to do certain tasks at different stages of their puzzling," he said. Used at the wrong time, even Blue Fuse would not give you an advantage. "The art of discovery still rests with creativ
