In one of the clubs in your city there will be a billiards competition called 3d Billiard Piramid. You will be asked to play such a variant as the Pyramid. The table for the game will be visible on the screen in front of you. Balls in the form of a geometric figure will be located on it. There will be a white ball opposite them. You will need to hit one of the balls with a cue and try to pocket it. To do this, you will call a special line by clicking on the ball. With its help, you set the trajectory and force of the blow and, when ready, make it. If you calculated the parameters correctly, the ball you need will fly into the pocket, and you will receive points. Remember that you will need to pocket all the balls in the shortest possible time.
