Rivers and Mount Airy were fined for giving away more complimentary vouchers than they were allowed.
While casinos are allowed to give out vouchers for free slot play as a marketing tool, the amount distributed must correspond to a pre-approved plan. Both casinos acknowledged that employees had given out more complimentary slot play vouchers than approved in their plans.
The breaches were discovered after an audit was conducted of all complimentary slot play programmes up until 2018.
Rivers was fined $47,500 for giving out 407 too many slot play vouchers between 2015 and 2016. Mount Airy was fined $92,500 after it was found that 10 employees had together issued 491 too many vouchers between 2013 and 2015.
Both casinos have agreed to tighten controls around the authorisation of slot play.
