We can notice that this implementation of the stack is actually upside-down compared to a real-world stack of items: the stack grows downwards in memory, towards lower addresses. The important thing to remember is that the bottom of the stack is at a fixed address and that the top of the stack changes when an item is *pushed* on the stack or *popped* out. In the game's CPU, the **stack pointer** (SP) register always points to the top of the stack and the **base pointer** always points to the base of the current **stack frame** We can notice that this implementation of the stack is actually upside-down compared to a real-world stack of items: the stack grows downwards in memory, towards lower addresses.

You can now take a look at the [assembly program examples](https://github.com/simon987/Much-Assembly-Required/wiki/Assembly-program-examples).
