In the billiards "snooker" game, there are 15 red balls, one each of yellow, green, brown, blue, pink, and black balls. The pockets of black balls accumulate 2, 3, 4, 5, 6, and 7 points respectively. In the first stage of the game, all 15 red balls must be knocked into the bag first, and after each red ball is shot down, a ball of another color must be shot down. Put the balls back on the table after being knocked down; in the second stage, knock down the balls in the order of yellow, green, brown, blue, pink and black. So, how many points can you get in the "snooker" game?
