Picross DS (U)(DOMiNENT) ROM

Gameplay follows traditional Picross rules, where players use logic to mark each square as full or empty, eventually revealing an unknown picture. Additional modes allow players to create their own puzzles and send them to friends, download classic puzzles and compete in speed competitions with friends or random rivals via the Nintendo Wi-FI Connection, download classic Picross puzzles from previous titles and complete up to five timed daily challenges.
In all modes except Daily and Online Challenge, the player is given the opportunity to receive a "hint" which reveals one randomly selected row and column, which does not impact the player's time. Also, three types of background music can be selected (except for Classic puzzles and the unlockable level 11 "extra" puzzles), or the music can be turned off.

Picross is essentially a "nonogram" type puzzle game (also known as Paint By Numbers or Gridders). Basically, you have to fill in specific squares on a grid; the only problem is that they aren't always obvious. Numbers on the rows/collumns of the grid tell you how many squares to fill in. Using the process of elimination, you have to figure out logically which squares are and are not supposed to be filled in. This is made easier with a tool that lets you cross-out the squares that don't belong. If my description seems very confusing or vague, the game comes with a tutorial, so don't worry. There are tons and tons of puzzles in this game, and even a lot of downloadable puzzles as well! You can make your own and share them with friends, too. The music and atmosphere are very simplistic and relaxing, making this a perfect game to settle down with after a busy day. The sheer variety of content in this game (and the content that is possible) is huge and you'll be playing this game for weeks and weeks, if not months or years.
