Tango #116 in numbers

Puzzle #116 starts with 7 given cells, 2 equals signs and 5 cross signs, leaving 29 cells to deduce. Our solver fills them in 29 forced steps without a single guess: 11 from the no-three-in-a-row rule, 11 from a row or column that already had its three, 5 from an × sign, 2 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 6, column 2 is a moon: The × sign means these two cells must differ.
  2. row 3, column 3 is a moon: The = sign means these two cells must match.
  3. row 3, column 2 is a sun: The × sign means these two cells must differ.
  4. row 6, column 4 is a sun: No three of the same can be adjacent, so this cell is forced.
  5. row 2, column 2 is a moon: No three of the same can be adjacent, so this cell is forced.
  6. row 5, column 2 is a moon: No three of the same can be adjacent, so this cell is forced.
  7. row 5, column 1 is a moon: The = sign means these two cells must match.
  8. row 4, column 1 is a sun: The × sign means these two cells must differ.
  9. row 5, column 3 is a sun: No three of the same can be adjacent, so this cell is forced.
  10. row 2, column 1 is a moon: No three of the same can be adjacent, so this cell is forced.
  11. row 2, column 3 is a sun: No three of the same can be adjacent, so this cell is forced.
  12. row 4, column 4 is a moon: This row already has three suns, so the rest are moons.

The remaining 17 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.
