If you like games that require pinpoint accuracy, Cornerball puts your skills, reflexes, concentration, and patience to the test as you try to get a little ball as far as possible. The gameplay is as simple as can be. You start the game with a ball sitting still on a narrow path. When you touch the screen, your ball starts moving toward the opposite side of the path and runs into the wall at the end. Then, a second wall appears that makes the ball start rebounding from side to side. Your goal is to tap the screen at the exact right time to make the ball turn down the new path that opens up. The game continues until you make a mistake. As you go on, the ball moves at a constant pace, so all you need to do is concentrate and tap at the exact right moment so your ball doesn't fall to its doom.
