To identify a "hot" or "cold" table in a casino, one should observe the game dynamics and player behavior. A "hot" table features frequent wins and a lively atmosphere, attracting more players, while a "cold" table has players experiencing consistent losses, creating a more subdued environment. Noticing the frequency of winning hands and how long players stay can help gauge the table's temperature, as a hotter table often retains players looking to capitalize on the winning streak. Overall, the perception of a table's temperature is influenced by personal experiences and the energy of the game.
