Tango #61 in numbers
Puzzle #61 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: 14 from the no-three-in-a-row rule, 11 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 5, column 5 is a moon: The = sign means these two cells must match.
- row 6, column 4 is a moon: The = sign means these two cells must match.
- row 5, column 3 is a sun: No three of the same can be adjacent, so this cell is forced.
- row 5, column 2 is a moon: The ร sign means these two cells must differ.
- row 5, column 6 is a sun: No three of the same can be adjacent, so this cell is forced.
- row 6, column 2 is a sun: No three of the same can be adjacent, so this cell is forced.
- row 6, column 5 is a sun: No three of the same can be adjacent, so this cell is forced.
- row 4, column 4 is a sun: No three of the same can be adjacent, so this cell is forced.
- row 5, column 1 is a sun: This row already has three moons, so the rest are suns.
- row 4, column 1 is a moon: The ร sign means these two cells must differ.
- row 2, column 1 is a sun: No three of the same can be adjacent, so this cell is forced.
- row 6, column 6 is a sun: This row 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.
