When the pandemic locked people inside, Buffalo Games saw an unprecedented spike in demand for its puzzles. But just as demand was taking off, the company's Buffalo, NY factory was shut down under New York State COVID-19 mandate. As the largest manufacturer of puzzles in North America, the company had to get creative. First, Buffalo Games sourced from overseas and then ramped up manufacturing stateside when the factory was able to reopen in May. Since May, the company has doubled production, now making 2 million puzzles a month. Business Insider visits the factory to see how Buffalo Games did it.
