For pure relaxation I'd go with Stardew Valley – simple to pick up, no pressure, you just farm and explore at your own pace. Unpacking is another great one if you want something even more low-key, basically just organizing stuff with a chill soundtrack. If you're open to something a bit more interactive with quick sessions, I've also been enjoying casino-style games on https://vvegas.ca/ after work – easy to jump in and out without any commitment. All three are great for switching off after a long day.
