To succeed in guide Paper.io, you must direct an ever-moving square to cover as much area on the board as possible. You can only move up and down or left and right by swiping or tapping relative to your previous position. If someone crosses your path before you fully enclose an area, you'll die. If you cross your own path, you'll die. If you hit a wall, you'll die. That's it. But something about these very basic parameters makes for an addictive and engaging experience, and Guide Paper.io has created an appealing design to make it even better. Overall, Guide Paper.io is fun, addicting and definitely worth the free download, especially for .io fans. Those who maybe didn't understand the appeal of these games will enjoy the simplicity Guide Paper.io brings to the genre, along with the vibrant and charming aesthetics.
