Polarium Advance Bonus
Polarium Advance is a puzzle game for the Game Boy Advance from the makers of Actionloop. It involves flipping coloured tiles to make whole lines of one colour disappear.

You can unlock new tiles and new puzzle stages in Polarium Advance by connecting it with Actionloop, simply by inserting the Polarium Advance cartridge into the Game Boy Advance cartridge slot of Nintendo DS (or Nintendo DS Lite), and selecting Polarium Advance Bonus from the Actionloop Options menu.

Demo Download
If you have a friend who wants to try Actionloop for themselves, you can send a temporary demo of the game by local wireless connection using the same method as DS Download Play (see Multiplayer section). The demo includes 49 Challenge Mode levels and 2 Quest Mode stages, which remain playable for as long as the player's Nintendo DS is switched on.
