Rules: 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 2×2 square or larger. There are no wall segments on cells containing numbers.
Background: Tapa is one of my inventions, probably the most famous one. I invented when I was preparing a set for IPST in 2007.
