The record for the most casinos visited in 24 hours is 69 and was set by father and son team, Jack and Jeremy Freeman (both USA) in Las Vegas, Nevada, USA, on 27-28 August 2007.

The pair went to 69 casinos and ended the attempt after 19 hours as they could find no more casinos to play at. They played blackjack at every casino and kept a $5 (£3.15) chip from each one, meaning a loss of £345 (£217), but winning $30 (£18) from all hands played.
