Magnefix

From BoardGameGeek:

In Magnefix, each player receives a set of colored MAGFORMERS, plastic shapes that contain magnets and connect in interesting ways. Shuffle the task cards and place them face down as a draw pile in the middle of the table. One player reveals the top card of the draw pile, then all players immediately try to recreate the image shown. As soon as you're done, place your hand on the task card. If you are the first to do so and have built the construction correctly, you win the card. The game ends when all 55 task cards have been played. The player with the most cards wins.
