Disboard


 * "This is the Utopia that you guys dreamed of, the world on top of a game board, [Disboard]--everything here is decided by a game, even one's life and country borders!" ― Tet to the siblings.

The Boardtop World, Disboard is the world where the primary storyline of No Game, No Life takes place. This fantasy world was modified by Tet. After he became the sole victor of the war between the Old Deus, thus being granted the title of the One True God, he commanded the 16 different races to end all wars and implemented the Ten Pledges.

The term Disboard could have been derived from the two English words, Discord and Board. Discord means a disagreement, so Disboard means a disagreement on a Board(game)
