A free hole-growing game for the .io Games section, with 80-second battles against three computer-controlled rival holes. Start by swallowing small street objects, grow big enough for cars, houses and skyscrapers, and avoid larger holes that can swallow you. Each level brings a new city and tougher rivals; finish in the top three to advance. Runs in a browser on desktop, phone and tablet without an account or download, with local progress saves. Developed by crokocat.
