About Tango #686
- Tango #686 starts with 10 of 36 squares filled: 4 suns and 6 moons.
- It has 3 equals signs and 2 cross signs between neighboring squares.
- It has 10 pre-filled squares, more than the average of 7.1 across the previous 7 puzzles.
- This opening fills 3 squares by pure deduction from the 10 pre-filled symbols and the signs between squares, with no guessing.
- R5C2 and R5C3 are neighboring suns in row 5, and a third sun beside them would make three in a row, so R5C4 next to them must be a moon.
- The cross sign between R5C4 and R5C5 says the two squares must be opposites, and R5C4 was already shown to be a moon, so R5C5 has to be a sun.
- R2C1 and R3C1 are neighboring moons in column 1, and a third moon beside them would make three in a column, so R1C1 next to them must be a sun.
