# Tapa

## Background

TAPA is an acronym for Turkish Art Paint, and was developed by Serkan Yürekli for the 2007 Diogenes Internet Puzzle Solvers Club.

## Puzzle and Goal

An unsolved puzzle consists of a rectangular grid, some of which contain one or more numbered clues.

The goal is to color some cells to satsify the clues.

## Rules

The solved grid must satisfy the following conditions:

All black cells form a single orthogonally contiguous area.

Clues represent the number of black cells in adjacent cells. For instance, a clue of 2 1 means that there are two black cells together, then some white cells, then a single black cell, than some more white cells, in the eight (or five) adjacent cells.

Black cells cannot completely cover any 2x2 area.

## Variants

Janko.at provides several variations, including using hexagons, having clues that represent mathematical differences, and so on.
