It’s believed that in Ohio in 2012 there was a mass roulette scam involving as many as 70 people. The scatter gun approach would involve players placing as little as $1 while swiping chips when the dealer was distracted. The chips would then be passed on to another member of the group before being cashed out.
Effective as it was, this clearly wasn’t the most sophisticated of scams and so various members of the group were caught in the act, or later via the viewing of CCTV footage. Authorities believe the gang were actually operating in numerous states and continue to this day. Those that have been caught have received penalties ranging from $2500 fines to a year in prison.
