Polarium (直感ヒトフデ or Chokkan Hito-fude in Japan) is a Puzzle game developed by Nintendo 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.
Game modes
- Challenge: Blocks of tiles continuously fall from above. Players must rapidly clear tiles by drawing lines to create horizontal rows of the same color. The mode becomes increasingly difficult for every 100 lines that are cleared, and the game is ended when 1,000 lines are cleared.
- Puzzle: Players must figure out how to clear complex puzzles in one continuous stroke. Players are challenged to clear 100 included puzzles or create their own custom puzzles. Numerical passwords to these puzzles can be generated and swapped with friends.
- Versus: Compete against friends to clear puzzles. As you clear lines, they'll appear on your foe's screen. Flip your opponent's tiles, earn power-ups, block their border tiles, and more.
- Lounge: The place to access tutorials, manage game preferences, and wirelessly sync with other players to exchange custom puzzles.
How to play
Select tiles by drawing lines over them with your stylus. Selected tiles will flip from black to white or vice versa. In the standard Tetris-like challenge mode, players must make room for falling tiles by clearing rows as they pile up on the bottom screen. Rows are cleared by flipping the tiles to make rows that are all black or all white. Surrounding the main puzzle area are gray "neutral" tiles that have no effect on the puzzle but can be used to flip disconnected groups of tiles in a single pass. The scoring in Challenge and Versus mode are based on how you clear the lines; for example, more points are given when more lines are cleared (lines), when numerous lines are cleared with just one stroke continuously (chains), when there are 2 separate lines cleared with uncleared lines between them (split), or when several lines are cleared in one stroke, but different lines have different polarities (borders).
