How to play memory

The rules are simple. When you see a word in the first language in one of the squares, you should try to find the matching word in the other language in one of the other squares.
To see what's in a square, click on it.
You can only see two squares at the same time, so the challenge is to remember what's in the boxes you have already looked at.
