About io games

.io games are fast arena games where you start small and grow by eating food and smaller opponents. In Worm Arena you trap other worms with your growing body, and in Blob Arena you dash to swallow smaller cells while dodging bigger ones. Every round is quick, simple to learn and endlessly replayable.
