Daily Galaxies

Galaxies, also known as Spiral Galaxies or Tentai Show, scatters white circles across a grid, some in the middle of a cell, some on an edge or a corner between cells. You draw walls along the grid lines to split it into regions, the galaxies. Each galaxy holds exactly one circle, and that circle is its centre of rotation: turn the galaxy 180 degrees around the circle and you get the same shape in the same place.

Puzzle-galaxies.com has Normal and Hard grids from 5x5 to 15x15, plus Special Daily, Weekly and Monthly puzzles. The daily is one dated grid for every player and runs larger than the regular list; the puzzles for 2 and 22 October 2026 were both 20 by 20. You click between dots to draw a wall, right-click to mark a gap with an X, and Shift-click to colour a square, which helps keep track of which galaxy a cell belongs to. The site shows ads, and patrons can remove them and reopen the last 30 dailies. The site keeps a Hall of Fame and statistics pages, and it has translated versions in more than a dozen languages.

Galaxies is a good choice for players who think visually: the symmetry rule means each cell you assign has a mirror cell on the other side of its circle. It suits fans of Shikaku who want regions that are not just rectangles.
