About Tango #688
- Tango #688 starts with 6 of 36 squares filled: 3 suns and 3 moons.
- It has 3 equals signs and 3 cross signs between neighboring squares.
- It has 6 pre-filled squares, fewer than the average of 6.3 across the previous 7 puzzles.
- This opening fills 4 squares by pure deduction from the 6 pre-filled symbols, with no guessing.
- R2C3 and R2C4 are neighboring moons in row 2, and a third moon beside them would make three in a row, so R2C2 and R2C5 on both ends must be suns.
- R4C4 and R4C5 are neighboring suns in row 4, and a third sun beside them would make three in a row, so R4C6 next to them must be a moon.
- R2C2 and R4C2 are both suns with only R3C2 between them in column 2, so another sun there would make three in a column; R3C2 must be a moon.
