About Tango #660
- Tango #660 starts with 4 of 36 squares filled: 1 sun and 3 moons.
- It has 5 equals signs and 3 cross signs between neighboring squares.
- It has 4 pre-filled squares, fewer than the average of 7.9 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.
- R3C2 and R4C2 are neighboring moons in column 2, and a third moon beside them would make three in a column, so R2C2 and R5C2 on both ends must be suns.
- The equals sign between R2C2 and R2C1 says the two squares must match, and R2C2 was already shown to be a sun, so R2C1 must be a sun too.
- The cross sign between R5C2 and R6C2 says the two squares must be opposites, and R5C2 was already shown to be a sun, so R6C2 has to be a moon.
