How many plays did Sophocles write for dramatic festivals?

Sophocles is credited with writing 123 dramas for the Athenian dramatic festivals.12

Because each playwright selected for the competition typically presented four plays—a tetralogy consisting of three tragedies and one satyr play—it is estimated that Sophocles competed in these festivals approximately 30 times throughout his career.2

Of this extensive body of work, only seven tragedies survive in their entirety: Ajax, Antigone, Trachinian Women, Oedipus the King, Electra, Philoctetes, and Oedipus at Colonus. Additionally, a significant portion of a satyr play titled Trackers remains as a 400-line fragment. Sophocles enjoyed unparalleled success during these festivals, securing perhaps as many as 24 victories.132
