Preston Estabrook, 7, of Monmouth reacts as he racks up points during a game of Ice Ball at the new Joker’s inside the Auburn Mall on Sunday. Featuring arcade games, train rides, food and an “a-maze-zing playhouse,” Joker’s celebrated its grand opening on Sunday. “We were cruising the mall and decided to check it (Joker’s) out,” said Estabrook’s mother Karen. “We stumbled on to this. It’s great,” added Preston Estabrook’s dad, John. Joker’s is open during regular mall hours.
