MSRA News: Golden Number Game

Rules

There are N players, begin a competition round of Goldennum. Every round, every player submits 2 float numbers in the open interval (0, 100) to the server. At the end of the round, the server will calculate the average of the numbers submitted during this round as AVG. Then the Goldennum of the round is calculated as AVG * 0.618. For every submitted number, if it is the closest number to the Goldennum, the submitter gets N-2 points, if it is the furthest number from the Goldennum, the submitter gets -2 points, otherwise, the submitter gets no points. After the rounds ends, player with the most points wins the game.

For players, take a look at our Participation Guide!

If you want to host a game but having trouble deploying on your server, feel free to contact me. I am glad to open a lobby on my server for you.
