What is freeze out poker?

Freeze-out poker refers to a type of poker tournament that
has three main characteristics:

1. As the previous answer
notes, in a freeze-out poker tournament, chips are bought at the beginning of the
tournament, and once play begins, may not be re-bought.

2.
Play continues until only one player has all of the
chips.

3. The most striking characteristic of a freeze-out
tournament though is that tables are "broken." In other tournaments, such as a shootout
tournament, as players are eliminated from play, the number of tables remain the same,
but the number of players at each table drops. However, in a freeze-out tournament, as
players are eliminated from play, floormen will stop play at tables with less players
and send the remaining ones to fill-in empty seats at other
tables.

Thus, in a freeze-out tournament, the number of
players at each table remains the same, but the number of tables fall, instead of the
reverse as in a shootout tournament.
