Overview

Gamemaster is an online competition environment for General Game Playing. On each "cycle", it selects a game at random from its game repository, and it selects players at random from its roster of available players. If there are enough available players for the chosen game, its runs a match and records the results in its database. Otherwise, it waits a minute and tries again with another randomly selected game.

The homepage has links to resources, software, games, registered players, metagamers, recent matches, a game manager, and a leaderboard.

Clicking on Leaderboard shows the relative performance of all registered players. The drop-down list at the top allows you to select a particular game set or the set of all games. The resulting table shows the performance of each registered player on all games in the selected game set. The unparenthesized number in each cell represent the adjusted score of the player and game corresponding to that cell. (Adjusted score is average score on the game multiplied by n/(n+1), where n is the number of matches of that game played by the player. This factor gives higher weight to the scores of players who have played many matches of each game.) The parenthesized number in each cell gives the number of matches the player has played. The Average column shows the players average over all games in the game set. Clicking on a column head reorders the table by the entries in that column.
