Most sports grow out of a simple formula—ball plus stick, ball plus kick, or car plus explosion. Celebrate simplistic styles with today’s game-garbed Groupon: for $10, you get three drop-in sessions for roller hockey, ball hockey, or futsal (a $21 value) at Sunplex Sports Arena.

Located on Ellis Street, Sunplex Sports Arena is a privately owned indoor sporting venue that hosts a wide array of roof-topped sports. Sun-shy sportsmen can drop in on any number of ball-centric back-and-forths, including roller hockey, ball hockey, or futsal. FIFA-approved futsal is an incarnation of indoor soccer that pits two five-person teams against one another on a wall-less playing surface, making for more strategy and less of the treacherous geometry of traditional indoor soccer. Meanwhile, roller hockey and ball hockey allow athletes to improve their hand-eye coordination while successfully avoiding rouge zambonis. Each of Sunplex's inspired athletic bouts take place on polyethylene flooring, known for its improved traction and gentle, knee-forgiving surface.

Invoke the athletic muses in the climate-controlled locker rooms complete with showers, or pour a libation to Lord Stanley and his enchanted chalice in the 30-seat bar and grill. Setting their sights on the two upper viewing levels, players can strike poses to garner the attention of lay-announcers and spectators. Roller-hockey players should arm themselves with a helmet, shin guards, gloves, rollerblades, and a stick, and ball-hockey hopefuls should bring gloves and a helmet. Sunplex offers equipment for rent, and though drop-ins are welcome, league play is common, so call ahead for availability.
