One More Line is a single-button arcade game where players move a disc as far as they can through a course full of obstacles, which they have to dodge in a very specific way: grabbing onto them and balancing on them.
Gameplay in One More Line is very simple: you have to hold your finger down on the screen so that the disc hooks onto one of the obstacles you find along the way. The disc will then orbit around the obstacle. When you take your finger off, the disc will ping off and you then have to hook onto the next obstacle.
With this simple gameplay, you have to try to get as far as you can on each level. It's not easy, since your disc sometimes orbits very closely around an obstacle, making it very hard to know which direction it will ping off in. And if you hit one of the walls, the game ends.
One More Line is an arcade game with a simple design but high difficulty. The visuals are excellent and the gameplay is brilliant for relatively quick rounds.
