2/3 the Average app for iPhone and iPad

2/3 the Average is a multiplayer game in which each of the players guess a number between 0 to 100, trying to get as close as possible to two-thirds the average of all the guesses made.

2/3 the Average offers three different modes of play: Pass n Play, Multiplayer, and Single Player. In Pass n Play mode, the players take turns entering their guesses into the device. In Multiplayer mode, two or more devices connect wirelessly, and each player enters their guess into their own device. In Single Player mode, a player plays against any number of computer players.

The game can be customized by changing the upper and lower limits on the numbers that can be guessed, and also by changing the ratio (half the average, three-fourths the average, etc.)
