Like learning to use chopsticks, roller skating takes patience, dedication, and a particularly dexterous set of toes. Watch foot flexibility in action with today’s deal: for $14, you get two general-admission tickets to the Big Easy Rollergirls’ home bout at the University of New Orleans Human Performance Center on Saturday, August 20 (a $24 value before fees, or up to a $26.82 value online, including all ticketing fees). Doors open at 6 p.m., and the wheels start rolling at 7 p.m. Kids 5 and under are always admitted fee.

The hometown girls of the Crescent Wenches roller-derby squad transform into eight-wheeled warriors as they battle the Cajun Rollergirls in a full-contact competition for skating supremacy. Bruising blocks and pileups characterize this high-energy sport, in which teams of up to 14 players vie for points and 8-bit golden coins on an oval flat track. Derby newcomers should have little trouble grasping the rules after the bout’s first few rotations, in which star-helmeted jammers weave their way through the pack to earn points while blockers obstruct their paths with well-timed hits and well-placed banana peels. While the girls lick their wounds during half time, the Pussyfooters cheerleading squad shimmies to the sounds of live music and rolling Elvis impersonators make a raucous pit stop on their pilgrimage to Graceland.

First-come, first-served seating and a full bar stocked with draughts from NOLA Brewing Company entice early arrivers, and the fried tortillas at Woody’s Taco Stand outside the arena mentally prepare spectators for the bout’s crunchier collisions (costs not included with today’s deal). Children are also welcome to attend the derby event, which benefits the Gulf Restoration Fund with a 50/50 charity raffle.
