Tapa Row

Tapa Row Rules:

• Tapa Row is a variant of the Tapa puzzle where the sum of all hint numbers in each row is equal to the number of black cells in that row.

• In addition to the above rule, Tapa Row follows all standard Tapa puzzle rules, including:

  • Empty cells can be filled in black to form a black region, and all black cells must be connected together.

  • There are no 2x2 areas in the grid that can be filled in black.

  • Hint cells with numbers cannot be filled in black, and the numbers represent the number of consecutive black cells in the eight surrounding cells.

  • If there are multiple numbers in a hint cell, the regions formed by these black squares must be separated by at least one white cell.

  • Question marks (?) can replace numbers, representing any non-zero positive integer.

Tapa Row Solving Tips:

• Use the row numbers to determine the number of black cells: Based on the sum of the numbers in each row, determine the total number of black cells in that row.

• Combine standard Tapa solving techniques: Combine solving techniques for standard Tapa puzzles, such as using numbers to determine the position of black cells, identifying isolated white cells, using the "no 2x2 black area" rule, and considering multiple number hints, to gradually fill in the blanks.

• Pay attention to the distribution of numbers in the row: When filling in black cells, pay attention to the distribution of numbers in the row to ensure that the number of black cells matches the sum of the row numbers.

• Flexibly apply reasoning strategies: Depending on the specific situation, flexibly apply different reasoning strategies, such as starting with rows with more numbers or prioritizing the determination of black cells in corner positions.

Tapa Row Puzzle Solving Summary:

Tapa Row puzzles add the restriction of row number sums to standard Tapa puzzles, increasing the difficulty and fun of the puzzles. When solving, it is necessary to comprehensively consider row numbers and standard Tapa rules for more rigorous reasoning and judgment. By practicing and summarizing experience, Tapa Row puzzle solving skills can be improved.
