Free Galaxies (Tentai Show) Online




Share this page to Google Classroom


Galaxies, also known as Tentai Show, Tentaisho, Spiral Galaxies, or Sym-a-Pix, is a binary-determination logic puzzle. It's a grid-based puzzle where the objective is to draw lines to divide the grid up into regions, forming symmetrical regions that resemble galaxies.



Draw lines along cell edges so as to divide the grid up into regions. Every region should have two-way rotational symmetry, and should contain exactly one dot which is in its center.

Click on a grid edge to add or remove a line. Right-click on a dot and drag the mouse to place an arrow in a grid square pointing to that dot, to indicate that you think that square must belong in the same region as that dot. Right-drag an existing arrow to move it, or drop it off the edge of the grid to remove it.
