About Tango #684
- Tango #684 starts with 9 of 36 squares filled: 4 suns and 5 moons.
- It has 2 equals signs and 3 cross signs between neighboring squares.
- LinkedIn rates it Hard.
- It has 9 pre-filled squares, more than the average of 7.4 across the previous 7 puzzles.
- This opening fills 4 squares by pure deduction from the 9 pre-filled symbols and the signs between squares, with no guessing.
- R1C3 and R1C4 are neighboring moons in row 1, and a third moon beside them would make three in a row, so R1C2 and R1C5 on both ends must be suns.
- The cross sign between R1C2 and R1C1 says the two squares must be opposites, and R1C2 was already shown to be a sun, so R1C1 has to be a moon.
- The equals sign between R1C5 and R1C6 says the two squares must match, and R1C5 was already shown to be a sun, so R1C6 must be a sun too.
