There is now weekly Tapa Variation Contest. I have created some of the Tapa puzzles for the practice of this contest, which I am posting it now. This puzzle also appeared many times in OAPC championships.
Paint some squares black to create a continuous wall. Number/s in a square indicate the length of black cell blocks on its neighbouring cells. If there is more than one number in a square, there must be at least one white cell between the black cell blocks. Painted cells cannot form a 2x2 square or larger. There are no wall segments on cells containing numbers.
