Trace Cadets

Trade Cadets is a four-player and duel minigame from Mario Party DS. In this minigame, the players are given a puzzle of differently-shaped blocks that they need to complete by etching out the outline of each block shape on the parchment, one-by-one.

Gameplay
The player is given a 3x2 grid on the lower screen for drawing out the borders of each block. First, look at the top screen and see which block in the puzzle is outlined in your character's colour; then draw out the outline of that particular block on the grid quickly in one stroke, without letting go of your stylus.

The blocks are all in different shapes, ranging from small triangles and squares to more complicated letter L-shapes. The aim of this minigame is to complete your puzzle before your opponents do.

Trivia

 * The name is likely based off 'space cadets', a phrase defining people who are lost in their worlds or daydreams. It's not clear what this has got to do tracing puzzles, though.
