The flying saucer acts as a cursor allowing you to select an activity. The 'speaker' button allows you to turn the sound on or off. The 'people' buttons allow you to select a difficulty level - the taller the person, the faster the game.
The games are car, spaceship, hot air balloon and submarine.
Car - press the switch to swap lanes and dodge other vehicles and road hazards.
Spaceship - dodge hazards in outer space.
Hot air balloon - control the hot air balloon and dodge the hazards in the sky.
Submarine - dodge hazards under the sea.
Collect as many jewels as you can in each of the games to increase your score. In each game you have three lives. If you crash the vehicle, your next life will begin. When you have used all three lives, the 'high scores' list will appear with your score.
