Trace Cadets

Trace Cadets is a 4-player and duel minigame that appeared in Mario Party DS. Its name is a pun on "space cadet", which is a term used for people who have their heads in the clouds.

Gameplay
A large grid of Tetrimino-like pieces will appear on four individual grids, and players will draw lines around the perimeter of the shapes. Whoever fills out their square first wins.

Winning
After the time is up, each part of the whole drawing is tallied, and the players win if they completed their grid first.

Controls

In-game text

 * Rules – "Build upon your corner by tracing the outlines of any bordering shapes. Here's a complication: you must sketch each shape without lifting your stylus."
 * Tips – "You can't trace just any shape on your field. The only pieces you can trace are those that are outlined in your character's color."
