Why they work
In the blues every chord is usually a dominant 7th (C7, F7, G7), even the I chord. Those 7ths are what give the blues its restless, unresolved sound.
The form is a question and answer: four bars on I, two on IV and back to I, then the turnaround (V–IV–I–V) that leads into the next chorus. Once you can hear where bar 9 is, you can play along with almost any blues.
