+\begin_layout Standard
+Pong is a game that consists of two paddles and a ball.
+ Each paddle is controlled by a player and the objective of the game is
+ to keep the ball between the two paddles.
+ If the ball reaches the opposite side of a players paddle then that player
+ loses while the other player scores.
+ The ball is displayed in the game as a dot and each paddle as a short vertical
+ line.
+ The paddles can only go straight up or straight down.
+ The ball moves with constant speed in one direction and never changes its
+ heading before it reaches a paddle or the boundary of the game area.
+ The logic of the bots In the Pong game can be simple and still behave realistic
+ by watching the ball and moving its pad up or down according to the position
+ of the ball.
+ In this way the game logic can be evaluated in constant time so that it
+ doesn't have a bad effect while measuring robustness.
  For the GGS there is no difference in serving a real user or a bot.
