High-limit rooms run on unwritten rules that the main casino floor does not enforce, and knowing them is the difference between being welcomed and being quietly shown the door.

Dress smartly, keep your phone away from the table, and handle chips and cards exactly as the dealer asks, since these small habits signal respect for the game and the other players.

The deeper rules are social: do not celebrate other players' losses, do not offer unsolicited advice, do not slow the game with indecision, and tip the dealer when you win.

If you are new to a high-limit room, watch a few hands first, ask the dealer politely about anything you are unsure of, and remember that calm, quiet confidence is the real dress code.
