It is impossible to say how long a game will last. There are too many variables to say for certain, however, if we take the averages we can come up with a number. Usually, a game of poker is played by six people. So, if we take six players, the standard Texas Hold ‘Em game will take an hour to finish. However, this all changes depending on the situation. If you are playing in a tournament, a game might last 2+ hours, depending on the skill level of the tournament.
