Challenge involved putting together three different puzzles in a specific amount of time. For the first puzzle, teams were allowed to refer to the puzzle box for reference. On the second puzzle, they only had a minute to look at the picture and had to put it together from memory. The third puzzle was a 3-D cat, which was made up of puzzle pieces cut out of acrylic on OEDK's laser cutter.
WINNERS: Team #15, with engineering students Melody Tan, Madeleine Crouch and Benhang Sri, won the $300 prize, completing all three puzzles in a combined time of 30 minutes and one second.
