Northern Club Reno, opened May 1931- closed 1941.
Fuller has it listed with all games, craps, roulette, 21, faro, big 6, and poker. That does not mean it opened with a full fledged casino. As far as I know, no chips have been found.

Also a Northern Club in Searchlight opened in July, 1931. No closing date listed. Many of these records burned in the fire at the White Horse Inn in Reno.
