In this tutorial I'm going to guide you through setting up a cron job, that opens https://www.gog.com/giveaway/claim every day, which adds the game currently on giveaway to your account. I'm going to use a Raspberry Pi with Raspberry Pi OS, but any Linux distro should work, as long as it's powered on during the time you plan to run the cron job. If you don't have a Raspberry Pi at home, I'd recommend using a free VPS. Google Cloud and Oracle Cloud both offer a reliable, and free VPS. For the setup, I'm going to use Chrome, but any browser is feasible.
