In Tunnel, the goal is to keep the ball in the tunnel for as long as possible while controlling its speed and direction to rack up the maximum possible score. A single click of the mouse will get you started in this thrilling game. An unending 3D tunnel appears on the screen in front of you. It won't be necessary to manually roll your ball. Moving the ball left and right will keep it from rolling out of the tunnel, which is your goal. Remember to pick up the little balls as you go so you can rack up the points. Use the left and right arrow keys, or A and D, to control the ball's direction. Both your score and your current movement rate are shown in the top left and right corners of the screen, respectively. In-game information, such as movement speed and score, will be made available to you. The game's ever-shifting palette and plethora of moving hazards test players' ability to focus, observe, and react quickly. Here's your turn!
