Jerry,

I can't speak about these specific chips at Comanche Nation, but a form of roulette was played in Oklahoma starting in about 2014. Oklahoma roulette still required the use of chips to place bets on the table, so these could be the ones used at Comanche Nation...not sure.

Oklahoma gaming laws back then required that all table games be card based, so the casinos came up with ways of playing roulette and craps using cards. They used regular roulette and craps tables, but no roulette ball or dice, respectively. Weird. You had to see it to believe it.

About two years ago, Oklahoma changed its gaming laws to allow normal roulette and craps.
