The hard-plastic Game Chamber has eight rotating slots, and comes with eight "blank" cartridges. You'll fill the eight slots with up to eight actual game cards; if you have fewer, use the "blanks" in their place, but every slot has to be filled. Once a game card is removed through the single-access door, the chamber will NOT rotate to allow access to another game until that first one is replaced. As long as you, as the parent, make sure there are no extra, unused, "blanks" scattered around, your child will have to put back each game cartridge before removing the next one.
Includes wrist strap, plus self-stick label for identifying each game in its slot. For Nintendo DS and Nintendo DS Lite game cards only.
