There was a transitional period that Harrah's Tahoe expanded into the middle building (between Harrah's & Barney's), before it took over both buildings and renamed as Bill's.
It was called Harrah's Sports Casino. Had a few table games, plus their poker room, a small lounge & food service, and a few rows of chrome plated old-style (non-electronic) slot machines. The last of these type machines that I recall.

I liked the informal feel of the poker room. One time had a pretty lucky run at poker and played until dawn.
