Since its Netflix release in September, Korean survival drama Squid Game has become an international pop culture sensation. It’s also generated a swell of interest in learning how to speak Korean.

As Reuters reports, the number of U.S. residents registering to learn Korean on Duolingo spiked by 40 percent in the two weeks after the series debuted. In the UK, the increase was even more impressive: 76 percent.
