SpiderXonix is based on the eighties game Xonix. Spiders, flies and a monster are on the playing field. Flies spawn only on the brown background of the field, the monster only on the blue, and the spiders move everywhere. Managing the spider, spinning a spider web, you must cut off the territory on the playing field, while preventing a fly from colliding with a spider web or spider. The truncated territory, free from flies, is flooded with blue, or the background of the picture opens (depending on the mode selected). When more than 70% of the field is captured, you advance to the next level of complexity.
