A labyrinth puzzle provided with a single inlet designed to receive and retain a marble. The labyrinth includes at least one T-shaped passage formed by first and second channels, the second channel intercepting the first channel intermediately. The first channel forms the arms of the T, one arm being provided with a throwing station and the other arm having a trap at its end. The second channel or leg portion of the T defines at its end the marble destination. The marble in the labyrinth is thrown from the throwing station to the destination to release the marble from the labyrinth. In a preferred embodiment, two T-shaped passages are overlapped, a common channel functioning as the leg portion of the first T-shaped passage and the arms of the second T-shaped passage. In this manner, the destination of the first T-shaped passage becomes the throwing station of the second T-shaped passage, thereby requiring two successive throws of the marble to release it from the labyrinth.
