Elect

It is easier to select better of two options than to tell which one of the options is the best or the third best. Elects solves this problem by making list sorting a game. You can sort text lists or groups of images.

To sort lists, e.g. images, Elect uses Elo Rating System. Each image has a rating, which is a number. A higher number indicates a better image, based on their results against other rated images. The winner of a contest between two images gains a certain number of points in his rating and the losing images loses the same amount. The number of points won or lost in a contest depends on the difference in the ratings of the images, so a image will gain more points by beating a higher-rated image than by beating a lower-rated image.
