Imagine being taken into a dark room and given 4 minutes to search for cleverly hidden and camouflaged objects. This is exactly what the finals of Electrobuzz had in store, a treasure hunt for its 6 teams as they fished for objects in the dark. These objects were then given to the teams to test with the Metal Detectors they built in Round 2. The team with the most number of correctly detected objects receives maximum points and ultimately wins the event.
