The current offerings make up a pretty accurate microcosm of what it was like before the pandemic: a mix of digital lotteries, SRO, difficult rushes, and easy walk-up rushes.
Pass Over has rush readily available, and I would guess that Lackawanna Blues does too. I believe I've heard that Waitress has rush, and that Hadestown has SRO. I haven't heard specific reports, but I'd guess those are more difficult and/or inconsistent. Then there's the digital lotteries for several other shows.
