Tango #70 in numbers

Puzzle #70 starts with 5 given cells, 3 equals signs and 3 cross signs, leaving 31 cells to deduce. Our solver fills them in 31 forced steps without a single guess: 17 from the no-three-in-a-row rule, 8 from a row or column that already had its three, 3 from an × sign, 3 from an = sign. Every step uses the three basic rules, so this is a board you can finish without ever having to list possibilities.

  1. row 1, column 2 is a moon: The × sign means these two cells must differ.
  2. row 2, column 2 is a moon: The = sign means these two cells must match.
  3. row 1, column 3 is a sun: No three of the same can be adjacent, so this cell is forced.
  4. row 2, column 3 is a sun: No three of the same can be adjacent, so this cell is forced.
  5. row 2, column 5 is a sun: No three of the same can be adjacent, so this cell is forced.
  6. row 3, column 2 is a sun: No three of the same can be adjacent, so this cell is forced.
  7. row 3, column 3 is a moon: No three of the same can be adjacent, so this cell is forced.
  8. row 3, column 4 is a sun: No three of the same can be adjacent, so this cell is forced.
  9. row 2, column 1 is a sun: This row already has three moons, so the rest are suns.
  10. row 3, column 1 is a moon: No three of the same can be adjacent, so this cell is forced.
  11. row 4, column 2 is a sun: This column already has three moons, so the rest are suns.
  12. row 6, column 2 is a sun: This column already has three moons, so the rest are suns.

The remaining 19 cells follow the same way; the hint button in the puzzle above walks through every one of them with its reason.

Rows and columns are counted from the top-left. Every daily Tango Unlimited board is generated to have exactly one solution and to be solvable by deduction alone; the how-to-play page explains each technique.
