When you receive your IXXI, the cards are arranged in order in the box. Even though the backs of the cards are not numbered, you can still easily lay them out and click them together.
You can flip the IXXI by taking it off the wall clips entirely and turning it over. You will then see the X- and I-connectors on the front. We think this creates a fun effect, but we understand if you prefer not to see the connectors. In that case, carefully detach the cards and flip the image. Use the click tool to easily reattach them. The card that was in the top right on the front will now be in the top left, reversed.
In the video below, you can see how to detach the cards.
