Toy billiard, of the type comprising a base frame that defines a playing surface on which lever means are provided for the thrust of the ball, throwing means for the ball and fixed obstacles, characterized in that it comprises, on said game plane, bistable oscillating obstacles and obstacles to hit associated with a bistable scoring display, as well as means of zeroing to reach the initial game conditions again. Billiard according to claim 1, characterized in that said launching means for the ball are constituted by a launching lever, of elastically flexible material, fixed, at one of its ends, to the game plane and having the other of its ends arranged at the base of a launching channel, a fixed stop defined on the playing surface acting on a middle portion of said launching lever. A billiard according to the preceding claims, characterized in that it comprises a recovery channel that merges with said launch channel, said recovery channel being at its lower end, controlled by a stop lever, of elastically flexible material, having a fixed end at base plane and the other end that interests the recovery channel. Billiard according to any one of the preceding claims, characterized in that said bistable oscillating obstacles are constituted by a pivoting body around bolts and having an external part with a punctuation indication and an internal part that emerges, through an opening, in a shell provided in said game plane. A billiard table according to any of the preceding claims, characterized in that said external part has a greater weight than the internal part in order to maintain said bistable oscillating obstacles in a collapsible position in the absence of said ball in said shell. 6. Billiard according to any of the preceding claims, characterized in that said obstacles to strike have an upper part in the form of a target that develops radially from a sleeve rotatably associated with a first axis arranged parallel below the game plane, developing from said sleeve, in the lower part, a leg element that ends in a hook part, with said leg element acting as a contrast spring having the other end thereof housed in a fixed cup-shaped element. 7. Billiard according to any of the preceding claims, characterized in that said hook-shaped part is able to be coupled with a ratchet part provided in a numbered body rotatably supported by a second axis parallel to said game plane, said numbered body having a numbered plate to take two positions, a first position lowered in which it is flush with said game plane and a raised position in which it is visible. 8. Billarin according to any of the preceding claims, characterized in that said numbered body has a hook for coupling with the end of a tension spring having the other end attached to a fixed point and able to push said numbered platelet to said raised position. 9. Billiard according to any of the preceding claims, characterized in that said numbered plates are housed in a projecting dome element of said game plane and that frontally presents an optically transparent surface. 10. Billiard according to any of the preceding claims, characterized in that said zeroing means for said numbered bodies are constituted by a comb-shaped element slidably housed in the bottom of the support container of said first and said second axes, said a comb element, on its rear part, a backrest from which, to the front part, fit to fit by contact with the ratchet part of said numbered body to overcome the elastic traction force exerted by said spring means elastic traction exerted by said traction springs, to bring said numbered plaque back to the folded position and realize the engagement between said pawl part and said hook part. 11. Billiard according to any of the preceding claims, characterized in that said zeroing means comprise a traction element that slidably engages below said game plane, said traction element being, on its front part, coupled with the front end of said comb element, and defining in correspondence with the fixed obstacles seats provided below the through openings, as well as said shells in correspondence with said oscillating obstacles. 12. Billarin according to any of the preceding claims, characterized in that said traction element has a gripping tongue protruding superiorly from said game plane and accessible from the inside to exert said traction. 13. Billarin according to any of the preceding claims, characterized in that said traction element has a closure element able to prevent the passage of the balls through said recovery channel. 14. Billarin according to any of the preceding claims, characterized in that they comprise an elevation articulated in correspondence with the upper end of said base reinforcement through coupling means constituted by an elongate plate housed in an edge provided on the sides of said elevation, said platelet having at its ends a pivot of rotation that develops perpendicularly with respect to the plate itself and which passes through said side of the base frame and said sides, a lock spring acting between the internal part being further provided. Of the sides of the base reinforcement and a closing washer coupled to said pivot of rotation, developing on the other end of the plate a fixing pin suitable for inserting in a through hole provided on the side of said base frame. 15. Toy billarin. (Machine-translation by Google Translate, not legally binding)
