If you have any questions, Jackpot City casino offers assistance 24 hours a day, seven days a week. At the touch of a button, a live chat function links you with an available agent. This is also true for Jackpot City mobile clients who use their smartphones and tablets to access the site. Unfortunately, the Jackpot City Casino does not appear to have a telephone hotline. You can, however, use the dedicated email address to contact the customer service team as an alternative.
