ApoPolarium is a nice looking, highly addictive puzzle game. The original Polarium (Chokkan Hito-fude (直感ヒトフデ, Chokkan Hito-fude) in Japan) is developed by Mitchell Corporation for the Nintendo DS. In the game, players use a stylus to draw lines on the DS's touch screen, flipping black and white tiles to clear puzzles.

But the nds-game is to hard in my opinion and I dislike the controls.
Thats the reason why I made this java-game. =)
