About Tango #670
- Tango #670 starts with 8 of 36 squares filled: 6 suns and 2 moons.
- It has 2 equals signs and 2 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 5 squares by pure deduction from the 8 pre-filled symbols and the signs between squares, with no guessing.
- The equals sign between R1C1 and R1C2 means they share a symbol, and with a sun on R1C3 right beside them in row 1, a pair of suns would make three in a row, so R1C1 and R1C2 must both be moons.
- The cross sign between R1C1 and R2C1 says the two squares must be opposites, and R1C1 was already shown to be a moon, so R2C1 has to be a sun.
- The equals sign between R5C6 and R6C6 means they share a symbol, and with a sun on R4C6 right beside them in column 6, a pair of suns would make three in a column, so R5C6 and R6C6 must both be moons.
