Still, those who love duckpins continue to swear by them. They note that both the old and young can play — as opposed to the more traditional tenpins, where balls that start at eight pounds are simply too heavy for some people. They boast that the game is more difficult, and thus takes more skill. No one, for instance, has ever bowled a perfect game — 12 strikes in a row for a score of 300 — in duckpins, while plenty of people have done so in tenpins.
