The Sims 4 Lovestruck allows you to find love for your Sims in creative ways, including blind dates.
To go on a blind date, you first need to open the Cupid’s Corner app on your Sim's phone.
The blind date option is a bit hidden, so you need to select it before opening the Cupid's Corner app completely.
Once you choose a blind date, you can customize it by selecting activities and deciding where to meet your Sim's potential love interest.
