* A game that uses sprites to manage the x and y coordinate values of the different objects.
Your project might use variables to store the values of sprites, which are special structures that contain an x and a y coordinate together that describe the sprite's location as one LED on the screen.

Now let's add some more types of instructions for the player to follow. Let's add `"PRESS PIN 0"`.
Change the global variable `action` to `math.randomRange(0, 3)` so that we can add a new **IF** statement that checks if `action == 3`. If it does, display instructions to press pin 0.

Each @boardname@ contains a **blockchain**, a sequence of **blocks**, that is public and can't be modified. Each block represents a **coin**. To mine new coins, the user shakes
the @boardname@ and, if they are in luck, their coin added to the chain as a new block!
Once the block is added, it is broadcasted to the other @boardname@ (the block chain is public and can't be modified so it's ok to share it). Other @boardname@s receive the block, validate the transaction and update their block chain as needed.
