Why did the chicken climb the ladder? To lay some eggs of course. Grab your basket And catch those falling eggs before they break.

To run this program, you will need

• Colour Maximite
• PS/2 Keyboard
• MMBasic 4.3 Or Later
• VGA Monitor
• SD Card with EggDrop files (attached above)
• Speakers (optional)

To control the basket, use Left/Right Arrow keys.

Hit

ESC

to exit the game.

Eggs will start falling slowly toward the floor. * Catch = 1 “Score” point. * Miss = 1 “Break” point.

For each catch, the falling speed will increase.

The Game is over after 5 broken eggs.
