The gameplay works like previous games but with some differences. Like before, a level is completed by capturing 75% of its area and two different enemies (sparx and qix) prevent the player from doing so. What's new is that the playfield also contains one beast and a chest which contains a treasure. The player can collect treasure by first capturing the beast which causes the chest to open and then capturing the object that is revealed. In this way, it's possible to capture up to three pieces of treasure per level. There are also various items to collect that give certain advantages when used.
In addition to the treasure mode, there is also a battle mode and a version of the original Qix . The game was released for the Game Boy Color on 2000-12-15 , and falls under the action & adventure genre.
