About Tango #687
- Tango #687 starts with 4 of 36 squares filled: 3 suns and 1 moon.
- It has 4 equals signs and 4 cross signs between neighboring squares.
- It has 4 pre-filled squares, fewer than the average of 7.4 across the previous 7 puzzles.
- This opening fills 4 squares by pure deduction from the 4 pre-filled symbols and the signs between squares, with no guessing.
- R3C5 and R4C5 are neighboring suns in column 5, and a third sun beside them would make three in a column, so R2C5 and R5C5 on both ends must be moons.
- The equals sign between R2C5 and R2C4 says the two squares must match, and R2C5 was already shown to be a moon, so R2C4 must be a moon too.
- The cross sign between R2C4 and R2C3 says the two squares must be opposites, and R2C4 was already shown to be a moon, so R2C3 has to be a sun.
