Portal Box is a typical arcade game with 3D game art animation as matter of fact. You are able to control the green box to move on random direction on the platform. Whatever you do, the box will not stop until come to the end of that direction even though you only want to move one step. The more levels you completed, the harder levels you will play. Fortunately, there is a function for you to input the passcode to complete the levels you confused in Portal Box!
