Someone is trying to pass old paper pull tab tickets off at sites in the Twin Cities. They are trying to redeem low amounts, probably nothing that requires a prize receipt.
Please remind your employees to check the serial numbers before paying out any tickets.
If this has happened at one of your sites recently, you should contact the Gambling Control Board immediately.
You may want to spot check your storage to see if any games appear to have gone missing. My guess is that someone has gained access to some closed games and is going through them to pull out any winners that went unsold. If you see that something is amiss with your stored games, contact the GCB immediately.
