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:

  1. Clues indicate the number of odd and even consecutively shaded cells around them, but not the values.
  2. There must be one contiguous area of shaded cells, which is not allowed to contain 2x2 areas.
