Or are there just simple goals.

Goals are much more common in handball than in most other sports; usually, both teams score at least 20 goals each, and it is not uncommon to have a match end (say) 33-31. This was not true in the earliest days, when the scores were more akin to that of ice hockey, but as offensive play (in particular in terms of counterattacks after a failed attack from the other team) has improved, more and more goals have been scored after each match.

Who cares.
