Classic Mode:

Classic version of N-Back, where you'll keep seeing new figures and you have to specify in which properties they match the one you saw N figures ago.

Draw Mode:

In this mode, you'll either be shown a new figure or you'll be asked to draw the one you saw N iterations ago.

Reverse Mode:

In this mode, you'll be shown a sequence of figures, and then you'll be given a target shape. Your goal is to accurately specify how many figures ago you saw your target.

Select All Mode:

In this mode, you'll either be shown a new figure or a grid filled with shapes from which you have to select all those that have at least one property (position, shape, color) in common with the one you saw N figures ago.
