About Tango #721
- Tango #721 starts with 8 of 36 squares filled: 3 suns and 5 moons.
- It has 5 equals signs and 3 cross signs between neighboring squares.
- It has 8 pre-filled squares, more than the average of 7.4 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.
- R2C3 and R2C4 are neighboring moons in row 2, and a third moon beside them would make three in a row, so R2C2 and R2C5 on both ends must be suns.
- R4C3 and R4C4 are neighboring suns in row 4, and a third sun beside them would make three in a row, so R4C2 and R4C5 on both ends must be moons.
- The equals sign between R4C2 and R3C2 says the two squares must match, and R4C2 was already shown to be a moon, so R3C2 must be a moon too.
