The puzzle game Ziply challenges you to manipulate lines and numbers. On the playing field, several cells are numbered. The task is to fill the field with a continuous line passing through the numbered cells in ascending order. It should be taken into account that not all squares on the field are accessible for passage. This allows you to draw zigzag lines that connect the numbers and fill the field where a line can be drawn. If the cell is inaccessible, you simply cannot continue the line; you need to look for workarounds in Ziply.
