MINNEAPOLIS (WCCO) — Puzzle Warehouse, the largest puzzle distributor in the country, says sales are up a staggering 2,000% compared to the same time last year.

In the midst of COVID-19, with most of America staying in place at home, deliveries from the puzzle outlet are on a two-week delay, and they’ve added 30 employees to help with demand.

The company says its most popular item is the 1,000-piece puzzle.
