A bridge clock has four actuator means, one for each player at a bridge table. A first and a third of these actuator means are adapted to cause a first clock mechanism to stop and a second clock mechanism to begin to run, when activated by a respective bridge player. A second and a fourth of said actuator means are adapted to cause the second clock mechanism to stop and the first clock mechanism to run, when activated by a respective player of a playing pair. The first and the second clocks can be set to run individually for a predetermined total time, after which a signal is triggered by a first alarm means. A second alarm means triggers a signal when the time clock exceeds a predetermined value.
