Topologic is a game of logic and deduction, but also uses piece movement. Every game is played over two rounds. In the first round one player plays the role of the referee (who hides a secret), the other the role of the seekers. In the second round the roles reverse. The 5 seekers are moved across the playing field (an assembled area of connected Nestortiles). Then the referee counts the score of the currently occupied locations (1 point for a color and/or number match) and announces the sum of the scored points. As they get more information, the seekers can deduce where the secret is hidden. Topologic is abstract, but players are encouraged to come up with a thematic background they like. This even includes renaming the game for each session.
