NSUD is definitely at Silver at $1 denom on the main floor slightly east & south of the central main stage bar on the bank of 8 multigame machines that are glassed as DDB with a (DDB) Prog prompter (at around $4140 last weekend) .
I believe I played $1 NSUD on other machines at SL last weekend and I was surprised to find it. But, I wasn’t diligent in recording which machines had it. Too many had a 15/9/4/4 version and, as I had just spent time at Peppermill which is mostly all NSUD, I wasn’t looking to play deuces at SL.
Except that I always play some 25c FPDW near the SE corner entrance, which weren’t as slow as my last visit. The 25c coin dropper FPDW with Prog RFs at Silver triggered my video poker hobby ten years ago.
