Odd-Even Tapa is a variant of Tapa, in which the cells in a grid are split into either shaded or unshaded.
The objective is to divide the grid into shaded and unshaded cells, subject to the following rules:
- Clues indicate the number of odd and even consecutively shaded cells around them, but not the values.
- There must be one contiguous area of shaded cells, which is not allowed to contain 2x2 areas.
