Dear user,

It takes a while to load the pictures. Press the buttons a couple of times to repaint the screen. After a short time you will see no gray blocks anymore, and then you can start to play. I will start this letter with the game rules, then I will discuss how to use the applet, and I will finish with some remarks about the making of the applet, for those who are interested in programming.

Game rules

At the very beginning of the game 72 cards lay face-down on the table. The current player opens a first card, and then a second card. If they show the same picture, the player may remove them from the table, he recieves a point, and this very same player can open two cards again. If he has opened two different cards, he must close them, and the next player can play. The game is finished if all cards are gone. The player with the most points (= the most cards) has won.

How to play

Click a card to open it.
If you know the card with the same picture, open that card. Otherwise, click any card to open it.
Click again to take away the cards (if they are the same), or to close them.
If the cards were the same, go to step 1. Otherwise click anywhere and the computer opens a card.
Click anywhere again and the computer opens another card.
Click again to take away the cards (if they are the same), or to close them.
If you want to start a new game, press the button "New game". If you want to end the game, press show them all, and you can see the cards you were desperately seeking.

Programming

The source code of this applet is published at its own page. In this you will find a complete explanation of all of it. At this point I just have two remarks: If you want to have this applet at your own computer, you can download it. For the HTML file you must find the 'save as' button in your browser. For the other files: Just type them in as destination, and choose save file. You need the following files:

This HTML file: memory.htm.
The class files: memory.class and table.class.
The jpeg files: 0.jpg, 1.jpg, ... ,36.jpg.

If you want to use your own pictures: download all files, and replace the jpg's by your own jpg's. If you want to use larger pictures (current size is 35 by 35 pixels), download the sourcecode, fill in your size, and recompile. To do this you need the JDK, or Visual Cafe, or another Java developping environment.
You can also download a zipfile containing anything.
