Although they were confirmed for North America and the United Kingdom, most of Europe had heard nothing about these machines. A few forum members of "Gathering of Tweakers" (a Dutch techie site) reported seeing download stations in stores. The stations have demos of Polarium and Meteos available for download. It seems inevitable that the rest of Europe will be seeing download stations soon.

Download Stations allow you to use the "Download Play" option on your Nintendo DS to download temporary demos and videos. They will last until your Nintendo DS is turned off. North American Download Stations will be featuring demos of Brain Age, Mario Kart DS, True Swing Golf, Tetris DS, Meteos, and Pokemon Trozei as well as a movie of Metroid Prime: Hunters.

Polarium has such a simple theme to it that one might mistakenly believe that it is simple. While that may be true in part, the game is no pushover either. The layout of no more than an 8x8 grid of black and white squares can be deceiving to the eye until you get in and try it. But is there enough depth to warrant a purchase? Game Features:

    – 100 puzzles in Puzzle Mode
    –  Puzzle Mode hint system
    –  1,000 line Challenge Mode
    –  Challenge Mode practice stage
    –  2-Player Versus Mode
    –  Puzzle Edit Mode for potentially endless replay value
