The numbers 1 to 31 are arranged in 7 columns of colored tiles (6 red, 6 yellow, 6 purple, 6 green, 6 orange, 6 blue, and 5 white), and the goal is to put the days of the month in increasing order going clockwise and down. Similar to the Babylon Towers, and a similar solution can be used, although this puzzle is easier because there are two blank tiles at the bottom of the green, orange, and blue columns.
