About Tango #679
- Tango #679 starts with 8 of 36 squares filled: 4 suns and 4 moons.
- It has 1 equals sign and 7 cross signs between neighboring squares.
- It has 8 pre-filled squares, more than the average of 7.7 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.
- R2C2 and R2C3 are neighboring suns in row 2, and a third sun beside them would make three in a row, so R2C1 next to them must be a moon.
- R1C3 and R2C3 are neighboring suns in column 3, and a third sun beside them would make three in a column, so R3C3 next to them must be a moon.
- The cross sign between R3C3 and R3C2 says the two squares must be opposites, and R3C3 was already shown to be a moon, so R3C2 has to be a sun.
