High on a windy plateau, far from the city lights, pixel Nikola Tesla has built a wooden laboratory with a giant coil on the roof. Tonight he is getting ready for his biggest experiment, but the parts on his workbench were packed in matching sets and have been shuffled face down. The neighbours down the valley call the place Lightning Glimpse, because its windows never stop blinking.
Every few seconds the coil fires, and for a split second the flash lights up the whole bench, showing every part at once. Pixel Tesla uses those flashes to grab a quick look before the room goes dark again. Bulbs, magnets, batteries and dials have to be paired before the experiment starts, and each finished bench brings a bigger one. When the clock runs out, the coil powers down. How many benches can be sorted?
