About Tango #690
- Tango #690 starts with 8 of 36 squares filled: 3 suns and 5 moons.
- It has 1 equals sign and 3 cross signs between neighboring squares.
- LinkedIn rates it Hard.
- It has 8 pre-filled squares, more than the average of 6.3 across the previous 7 puzzles.
- This opening fills 3 squares by pure deduction from the 8 pre-filled symbols and the signs between squares, with no guessing.
- R1C1 and R1C3 are both moons with only R1C2 between them in row 1, so another moon there would make three in a row; R1C2 must be a sun.
- The cross sign between R1C2 and R2C2 says the two squares must be opposites, and R1C2 was already shown to be a sun, so R2C2 has to be a moon.
- R6C4 and R6C6 are both suns with only R6C5 between them in row 6, so another sun there would make three in a row; R6C5 must be a moon.
