you could have a type of 1 v 1/ team vs team contest mode that keeps track of accuracy and time taken to finish. all contestants would get the same set of review sentences irrespective of SRS level for that point (taken at random from the pool of 12). Whoever finishes with the highest accuracy (time if tied for accuracy) wins. You can have a unique badge that is transferable (to the winner upon losing a contest). You could also have other permanent badges associated with these challenges (compete in 10,20, 50, 100 contests, finish a contest within x,y,z time, finish a contest with 100% accuracy x,y,z times, win x,y,z consecutive contests etc). Bit of a tangent, but while I’m talking about badges, it would be really cool if we could have them visible on the forums, if not then it would be quite nice if we could create a type of avatar that could equip the armor/weapons themed badges which would be visible to our friends. the non accessory type badges could be a background of sorts or possibly converted to an accessory, something like a ghost pet for all the ghost buster badges. If that is too much work then maybe just make badges visible to friends.
I think for these contests it might be best to limit them to manual input reviews and to possibly disable the undo function or to give each player or team a hard limit of undo uses. You might also be able to add different modes that include simple flash games similar to something like quizlet’s race function.
