About Tango #669
- Tango #669 starts with 8 of 36 squares filled: 3 suns and 5 moons.
- It has 0 equals signs and 6 cross signs between neighboring squares.
- LinkedIn rates it Hard.
- It has 8 pre-filled squares, fewer than the average of 8.1 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 R3C1 are both moons with only R2C1 between them in column 1, so another moon there would make three in a column; R2C1 must be a sun.
- The cross sign between R2C1 and R2C2 says the two squares must be opposites, and R2C1 was already shown to be a sun, so R2C2 has to be a moon.
- The cross sign between R2C2 and R1C2 says the two squares must be opposites, and R2C2 was already shown to be a moon, so R1C2 has to be a sun.
