There are only a few important points to keep in mind as you play this simple game.
| 1. | The game is played in sets of usually 10 trials. | |
| 2. | While you are in the middle of a set you are not able to alter any of the game settings. | |
| 3. | When the program is waiting to start a set of trials, the menu button provides access to options to change the level and the direction of movement. |
| 4. | On the screen you will see a box drawn in solid red. The idea of the game is to trap the ball as it passes through the box on its journey across the screen. | |
| 5. | The position of the red box on the screen will vary from trial to trial. | |
| 6. | To capture the ball you only have to press the left mouse button when the ball is fully in the box. | |
| 7. | If you are SUCCESSFUL you will get a score which reflects how fast the ball is moving and how close the box was to the ball's start point. | |
| That's all there is to it! | ||
