Question

In which game is the word roll-in used?

Hint:

This term is about restarting play after the ball crosses the sideline in a stick-and-ball team sport.

Answer 1

Hockey is the sport where the term roll-in applies.
When the ball goes out over the sideline during a hockey match, a player from the opposing team gets to roll the ball back into play from that point. This is called a roll-in.
Earlier, hockey used a hit-in for the same situation, but it was later changed to the roll-in to keep the game moving and reduce delays.
