Most Reno games are playable
"Best games" depends on your betting level. All downtown stores except Siena are D10. Sparks stores are double any first two cards, but reasonable betting levels stand out, since most of their patrons are very low-level grinders. Baldini's is unplayable, due to paltry $50 table max. Pen is generally acceptable-to-good everywhere, except Golden Phoenix, and varies by dealer at some stores.
Worst sweatshops are Peppermill and Eldorado. Eldorado has the Mindplay cheating devices, and uses them blatantly to pref shuffle. Others with dealers who frequently pref shuffle are JA Nugget and Sands Regency.
