Qix tipe of game

hi, i can't quite understand how to create a game like qix , if anyone has any idea how to do it, can you explain it to me? the main problem is understanding how to close the conquered areas

As it happens, I'm actually working on a Qix game too. In the end I went for the following approach:
- Lower the resolution, since the algorithms required are quite resource intensive.
- Keep the play area as a one-dimensional array (which makes it easy to display on screen using the uploadImage() function.
- The various states a pixel can have (border, active line, empty space, etc.) are represented as different colours in the array, so you can always look at a specific coordinate in the array and see if it for instance is inside the empty playfield area or not by reading its colour.
- When the drawn line of the player comes back to a non-empty pixel, we should fill. What I do then is a Flood fill from the Qix enemy's position with a special colour, and then go through the whole play area and set all the pixels that still have the "empty space" colour as filled, and the "special colour" as non-filled.
It's hard to explain, but I basically used this article, and tried to do the same thing:
