About Tango #668
- Tango #668 starts with 8 of 36 squares filled: 4 suns and 4 moons.
- It has 1 equals sign and 3 cross signs between neighboring squares.
- It has 8 pre-filled squares, fewer than the average of 8.1 across the previous 7 puzzles.
- This opening fills 4 squares by pure deduction from the 8 pre-filled symbols and the signs between squares, with no guessing.
- The equals sign between R4C6 and R5C6 means they share a symbol, and with a sun on R3C6 right beside them in column 6, a pair of suns would make three in a column, so R4C6 and R5C6 must both be moons.
- R4C6 and R5C6 are neighboring moons in column 6, and a third moon beside them would make three in a column, so R6C6 next to them must be a sun.
- R5C4 and R5C6 are both moons with only R5C5 between them in row 5, so another moon there would make three in a row; R5C5 must be a sun.
