Rules for Tapa
Rules for Tapa filler
Create a continuous wall of digits; at most one digit per cell. Filled-in cells cannot form a 2×2 square. Number/s in a cell indicate/s all digits on its neighbouring cells; each digit appearing as many times as itself. In the case of identical-digit groups around a clue cell, groups cannot be edge-to-edge neighbours (e.g., the 2-2 clue on the example).
