Galaxies – Divide the Grid – Puzzle Game



This game is an implementation of Tentai Show, a puzzle invented by Nikoli, a puzzle magazine published in Japan.  The name “Tentai Show” has the double meaning of two fold rotational symmetry and astronomical show. In Japanese “Ten” means dot, “tai-Show” means symmetry, and “Tentai” means things astronomical.

You have a rectangular grid containing a number of dots. Your aim is to draw edges along the grid lines which divide the rectangle into regions in such a way that every region is 180° rotationally symmetric, and contains exactly one dot which is located at its centre of symmetry.

Game Types:

  • 7×7 Normal
  • 7×7 Unreasonable
  • 10×10 Normal
  • 15×15 Normal
  • Custom mode – define the width and height, set the level of difficulty: Normal or Unreasonable
