Concentration

The classic memory game. Below are card which begin face down. Click on one to turn it over. Try to find the second card that matches the first. If the second does not match, both cards return to a face down position. If they do match, the cards are removed to reveal part of the background image.

COLUMNS: This parameters tells the applet how many columns of cards to display. The default is 4.

ROWS: Indicates how many rows of cards to display. The default is 4.

IMAGE.#: This series of parameters defines the images of the cards which are to be matched. The first parameter is IMAGE.0, then IMAGE.1, and so on. Each image will appear twice in the puzzle (since the idea is to find hidden pairs), so you should define ROWS * COLUMNS / /2 number of these. All images should have the same dimension.

IMAGE.FACEDOWN: This is a single image is the generic 'facedown' image that appears when an image is not flipped over. The dimensions of this image should be the same as the dimensions of all the IMAGE.# images.

IMAGE.MASK: If you would like to embellish the look of the cards, you may define a 'mask' image that is some type of transparent gif that sits atop the other images after they are painted. For example, the applet above uses a shadowed effect overlay.

SOUND.PICK: A sound file that is played whenever a card is picked to flip over. Consult the FAQ if you are unsure what types of sound files you may use.

SOUND.CORRECT: A sound file that is played whenever a pair of cards is correctly matched. Consult the FAQ if you are unsure what types of sound files you may use.

SOUND.INCORRECT: A sound file that is played whenever a pair of overturned cards do not match. Consult the FAQ if you are unsure what types of sound files you may use.

SOUND.SOLVED: A sound file that is played when the game is solved (all cards are matched). Consult the FAQ if you are unsure what types of sound files you may use.
