Object
of the Game:
The object of the game is to hit the rectangular
target at the top of the screen by adding charges to the screen.
How to play:
Click on the Show Minefield button to
show the locations of the positive charges (the mines) which are randomly
placed on the screen. Click on the screen to add negative charges
into the minefield. You can change the magnitude of the charge using
the plus/minus buttons at the bottom of the screen. At any
time, you can draw the electric fieldlines of the charge distribution by
hitting the Draw button. Use the Delete Last button to delete the
last added charge. The Delete All button deletes all the charges
you have added.
When you are satisfied with the field,
hit the Start button to start the game. A positively charged object,
represented by a blue circle, will appear at the bottom of the screen.
It will move through the electric field created by the minefield charges.
You cannot alter the field while the charge is moving.
The game ends when the charge hits any side of the screen.
Hit the new button to play a new game,
or try again by adding/deleting charges to the minefield.
Scoring:
The score is calculated
using the distance from the center of the target to the upper left corner
of the charge. The score is a function of the inverse of this distance
(1/r).
