Today's Tango: October 1

Puzzle #9, medium. 8 squares of the 36 start filled, with 2 = signs and 2 × signs. Everyone gets the same board, and a new one arrives at 00:00 UTC.

How to play Tango

  1. Fill every square of the 6×6 grid with a sun or a moon.
  2. Every row and every column holds exactly three suns and three moons.
  3. No more than two of the same may sit next to each other in a row or column: never three in a line.
  4. An = sign between two squares means they are the same; a × means they are different.
  5. Tap a square once for a sun, twice for a moon, a third time to clear it. Squares that start filled are fixed.
