I know FoldIt very well and I use it for teaching (as a next step after modelling - its interface is much more suitable to explain nuances of model refinement than any other free tools). I'm aware of couple of others such as Phylo or EteRNA. The question is what other bioinformatics/cheminformatics/biology games are out there? I'm looking for games that can be used to explain basic biological and algorithmic concepts in the course of teaching bioinformatics and systems biology to undergraduates.
Citizen science aspect (like in FoldIt) isn't neccesary, but of course it would be nice to have it.
Just wanted to point out that http://genegames.org will be the portal for all our biology-oriented games moving forward. Thanks for the plug!
