Tango #101 in numbers
Puzzle #101 starts with 3 given cells, 3 equals signs and 3 cross signs, leaving 33 cells to deduce. Our solver fills them in 33 forced steps without a single guess: 19 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 ร sign. Every step uses the three basic rules, so this is a board you can finish without ever having to list possibilities.

- row 3, column 3 is a moon: The = sign means these two cells must match.
- row 3, column 1 is a sun: No three of the same can be adjacent, so this cell is forced.
- row 3, column 4 is a sun: No three of the same can be adjacent, so this cell is forced.
- row 4, column 4 is a sun: The = sign means these two cells must match.
- row 4, column 5 is a moon: The ร sign means these two cells must differ.
- row 2, column 1 is a moon: No three of the same can be adjacent, so this cell is forced.
- row 1, column 1 is a sun: The ร sign means these two cells must differ.
- row 5, column 1 is a moon: No three of the same can be adjacent, so this cell is forced.
- row 2, column 4 is a moon: No three of the same can be adjacent, so this cell is forced.
- row 5, column 4 is a moon: No three of the same can be adjacent, so this cell is forced.
- row 5, column 3 is a sun: No three of the same can be adjacent, so this cell is forced.
- row 5, column 6 is a sun: No three of the same can be adjacent, so this cell is forced.
The remaining 21 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.
