With over 500 puzzles to solve, the idea of "Pikurosu DS" is to guess what picture is hidden in the grid using the numbers given at along the edges of the grid as clues.

Aside from the main game mode, you can also make your own puzzles, versus up to five other players and also enjoy a daily puzzle mode where you can solve puzzles as quickly as possible or spot the difference.

Sound like fun! You can play this colourful game on January 25th 2007.
