Bowling is a classic game the whole family can enjoy. If your game room isn't large enough to accommodate an alley with a full-size lane, consider other options. Purchase a set of bowling pins and balls, and create a makeshift lane on the floor. You can also try duckpins, which are shorter and squatter than regular pins and are knocked over with smaller balls. If space is really at a premium, try a tabletop version made of wood, in which you "bowl" with mini pins and marbles.
