We will begin with classic memory game. Not just any memory game – the memory game that is the source of joy and frustration of children everywhere. In case you've never been exposed to this game (really?), the gameplay is simple. The playing field is a set of tiles with pretty pictures on the front, and a generic back image. You turn over two tiles to see if you made a match. If not, you turn them back over. Pick another pair of tiles and see if they match. Repeat this till all the tiles are matched. Let's take a look at the finished game:

Our memory game needs to be flexible enough to allow different skill levels in the game. We will create different skill levels by varying the number of memory tiles on the board. If there are four tiles (two each of two designs), that's pretty easy. Creating a 4 x 5 grid of tiles is a lot more challenging (20 tiles, 10 designs). We will build a single project that will handle these variations dynamically.

Our game will be a little different from the traditional version in two ways: it is single player only, and we will add a way to lose the game, to make it more exciting. We'll go into detail on that aspect later.
