About Tango #689
- Tango #689 starts with 8 of 36 squares filled: 3 suns and 5 moons.
- It has 3 equals signs and 1 cross sign between neighboring squares.
- It has 8 pre-filled squares, more than the average of 6.0 across the previous 7 puzzles.
- This opening fills 4 squares by pure deduction from the 8 pre-filled symbols, with no guessing.
- R3C5 and R4C5 are neighboring moons in column 5, and a third moon beside them would make three in a column, so R2C5 and R5C5 on both ends must be suns.
- R2C4 and R2C5 are neighboring suns in row 2, and a third sun beside them would make three in a row, so R2C6 next to them must be a moon.
- R5C4 and R5C5 are neighboring suns in row 5, and a third sun beside them would make three in a row, so R5C6 next to them must be a moon.
