Hasbro Inc. HAS 1.71% and Mattel Inc. MAT -2.07% enjoyed a boost during the Covid-19 pandemic as lockdowns spurred parents to spend on everything from board games to Barbie dolls for their children. Hasbro's game business was the standout at the company last year, with sales up 15% despite some supply shortages during the holiday shopping season. Families that began playing together bought classic versions of such games as Monopoly and Operation. Others rounded out their collections with special versions such as a Monopoly game featuring the Baby Yoda character from the "Star Wars" spinoff "The Mandalorian."
