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 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.
