Empty squares can be filled black to become black areas, and all black squares must be connected as a whole.
There cannot be four consecutive black squares in any row or column.
Clue squares marked with numbers cannot be filled black. The numbers represent the number of consecutive black squares in the eight surrounding squares.
If there are multiple numbers in a clue square, the parts consisting of these black squares must be separated by at least one white square.
Question marks (?) can replace numbers, representing any non-zero positive integer.
The rules of Tapa Classic apply, except for the following additional constraint:
No row or column can contain four consecutive black cells.
