Rules for Tapa

1. Tapa With Borders.

Follow standard Tapa rules. Additionally, there is a 6x6 puzzle hidden in this 10x10 grid. Locate the puzzle and solve the remaining grid.

 2. Tapa-Like Loop

In this Tapa the wall is formed by a single continuous loop. Clues inside the grid represent the number of neighbouring cells visited by the loop. If there is more than one number in a cell, each number should represent a separate section of the loop. In this puzzle, the no 2x2 rule of Tapa does not apply.

7. Dissected Tapa

Follow standard Tapa rules. Additionally the white cells and black cells form two congruent shapes. Clue cells count a white cells. The shapes may be rotated or reflected.


  1. For Dissected Tapa, why do the directions *always* say "the shapes may be rotated or reflected"? As far as I can tell, the only time a valid tapa either uses reflection or doesn't need rotation is when one dimension of the grid is 1 or 2. Am I missing something?

    1. It's because these variant rules are literally taken from Dissection puzzles. In Dissection puzzles making this distinction is more relevant.
