This puzzle originally appeared in Deception, as the Bottom puzzle of Elimination Tapa.

Elimination Tapa Nurikabe-style: Shade some of the cells black. Black cells must be connected, but no 2×2 square may be all black. Cells containing numbers may not be shaded black. A cell with numbers represents the lengths of contiguous black cells in the cells adjacent to itself, separated by at least one white cell between different groups.

In addition, each square with numbers has one extra number. Removing extra numbers is part of the puzzle. Question marks indicate unknown numbers.

Clearly intended to be a standalone post for this.

Yeah, reposting puzzles I’ve published somewhere else. This includes my old blog.

Also, yay, managed to disable anti-aliasing with a program!

Elimination Tapa Shade some cells black so the black cells form a tapa wall. No cell with a number or question mark may be shaded black. A cell containing a number tells the lengths of consecutive black cells adjacent to it; if there are multiple numbers, they must be separated (there must be at least one white square separating them). Question mark represents an unknown number. In addition, every cell with a number/question mark needs exactly one number/question mark removed before the actual set of numbers is obtained.

Answer key: Enter the lengths of the lines of black cells in the marked row/column. If the row/column has all/no black cells, enter 0.

If you don’t get the title, note that the clues on the first row are at column $1 = 1$ , $3 = 1+2$ , $6 = 1+2+3$ , and $10 = 1+2+3+4$ . Similarly for first column. Last row and last column are just rotational symmetry.
