Invert

Invert rearranges the columns by "inverting" them so that the orders of the column halves are flipped (example, in a 4 column game, the default order is 1234, invert makes it 2143)

If invert is used on a game mode with an odd number of columns (such as pump), the middle column becomes the first column, so it would be like: 32154.

To flip the invert mod, you cannot use just flip and invert because this spaces out the columns weirdly and sometimes puts columns on top of each other. You will need to use flip and -100% invert to make it work. Doing it this way puts the right half of the columns on the left, and the left half of the columns on the right (so 1234 becomes 3412).
