QueenDomination is a kind of pazzle game. This is a description from No-three-in-line problem entry on Wikipedia, the free encyclopedia.
In mathematics, in the area of discrete geometry, the no-three-in-line-problem, introduced by Henry Dudeney in 1917, asks for the maximum number of points that can be placed in the n × n grid so that no three points are collinear. This number is at most 2n, since if 2n + 1 points are placed in the grid some row will contain three points.
