The state Casino Control Commission last week approved a law to require winnings from slot machines and keno in the Atlantic City casinos be collected in one year.
After that, the money belongs to the casinos and the state.
Officials say there are $12.4 million in unclaimed winnings - much of it in very small amounts, often under $1.
The first deadline to collect is April 8 for all winnings over a year old. After that, the vouchers will be good for a year after they're issued.
The rules apply only to slot machines and keno, not to other games of chance.
The state and casinos are each to get a share of unclaimed winnings.
