Picked this up last week, looking to trade for another California roulette that I don't have. The "volcanic bingo" notation on the chip shows the way they do roulette. California law won't let Indian casinos use an actual roulette wheel so this casino uses balls and a blower such as Bingo games use to pick the numbers but the betting is just like roulette. Drop me an e-mail if you're interested in trading.
