I recently started to just go to random.org and taking number between 1-4, and going to SuttaCentral
Then, if it’s for example 2 - it’s Majjhimanikāya this time (1-4 as the 4 Nikayas), then going back to random number between 1-152 (total number of MN suttas) until an absolutely random sutta is ready to explore 
been very fun so far, maybe someone would find it fun this way too!
In this way it often turns into more than just that one sutta, for example SN 51.45-54 
Also, I get to re-read suttas over and over or explore Pali if I already know the sutta.
