There are probably 25 betting machines arranged in this setup. Sky River has a Shoot to Win bubble craps setup with one big bubble towards the center, and all the betting machines arranged in a circular formation around the center bubble. This place has a good buffet which makes coming here sort of worth the drive, but sort of not due to how many big reds the machines roll at least when I was last there. The comps are good on the machine, they give out more points on your card on the craps machines here. Couple times I've had back to back 7's on the CO roll. Had good luck there on two of the machines before, the one closest to the bar facing the main casino floor and one at the far back set of machines also facing the main casino, but ever since they took away 3 machines the remaining machines left seem to roll big reds more often on average every 2 to 4 rolls between each 7.
Red Hawk had 6 individual bubble craps machines up until beginning of February this year, then they reduced them to just 3 machines. So for bubble craps in NorCal, only places that still have them are Red Hawk casino in Placerville CA, and the new Sky River casino in Elk Grove CA.
Just wanted to update this thread for 2023.
