This is a very simple game. The One Way app shows you a path that you have to memorize and then re-draw the same path by swiping your finger on the screen.
How to Play:
*Memorize path from red dot to blue dot.
*Swipe (Up,Down,Left,Right) to draw your path.
*If both paths match, you move to the next level. Otherwise you lose your current level.
*Forgot current path? Press the "Start" button again.
