Tapa is a puzzle genre created by Serkan Yürekli.

  • Shade some cells in the grid.
  • All shaded cells must be connected.
  • No 2×2 square may be fully shaded.
  • Clue cells may not be shaded, and represent the number of shaded cells in each group of shaded cells in the cells surrounding the clue.
    • Note that the numbers may appear in any order.
    • As a special case, if the clue 0 appears, it represents the “empty clue” and no cells surrounding the clue should be shaded.
  • If a question mark appears in a clue, it may represent any number greater than 0.
