Rules: 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).
Background: The Tapa variation invented by Cihan Altay. Cihan made this type for the first time in TVC III. Also I made it for TVC IV and V. Actually I like this type much, so I made it for so many competitions like Puzzle Jackpot, ZeKa 2011 etc.
