Deadwood casino operators have talked about adding craps and roulette to the card games and slots that they have offered for two decades. But Ken Gienger, president of the Deadwood Gaming Association, says they aren't ready to ask voters for permission.

He says casino operators have to keep an eye on their competition, which includes Colorado casinos that were allowed to add craps and roulette in July.  State Sen. Tom Nelson of Lead says supporters probably won't push the idea of adding craps and roulette in the 2010 legislative session.

The state Constitution limits Deadwood casinos to slot machines and card games, which include blackjack and poker, so any change to allow craps and roulette would have to be approved by voters statewide.

The 20th anniversary of legal gambling in Deadwood is next week.
