This is an app that lets you connect dots like the sample. It develops your visual skills (eye movement, comparison) and spatial awareness (horizontal, vertical, up, down, left, right). It also helps you learn to read and write characters. The problems are generated automatically. You can adjust the settings such as the number of dots in horizontal and vertical directions and whether to use diagonal lines or not, to match your level of difficulty. It is scored automatically, so children can learn by themselves.
