All Challenges In Order!

Super Smash Bros Brawl 
Challenges

Yes, this is the same as the unlockables section, however, this has been usefully re-organized to be in order with the challenges section in game.

Lets start with a picture.

Challenges Screen

The blue squares are squares we know nothing about.

The red squares tells you how to unlock said square. A square turns red when the square to the left or right of it is unlocked.

Open squares and unlocked items.

The square with the green outline is the one I'm highlighting.

The golden hammers near the bottom indicate how may hammers I have left. The hammers can be used to instantly open any square, but you only have five of them so make them count.

The numbers and letters around the grid is my doing. Those numbers will be referred to below to mark what square an item is in. For example, the green outline is around square A:1.
