There is described a game of the see-saw type, wherein an extended bar or beam is oscillated up and down by children and/or adults sitting at the respective ends. According to the invention the central support can rotate around a vertical axis rotated if necessary by a motor reducer placed at the base thereof. Moreover, there is provided a counterweight, which can slide on the oscillating beam and can be moved by means of manual controls or automatically through sensors for detecting balance positions of the beam itself. It is thus possible to use the game for a single user, whereby the see-saw acts also as a balance by making use of the counterweight position, or for several users having different weights, the balancing of the two arms of the beam being ensured. In order to use the game on payment there may be provided a slot-machine, connected to timers and automatic devices for the possible operation of the rotating motor reducer, even at different speeds and for returning to the initial conditions with the counterweight in the central position. |
