Black Hawk casinos are MOSTLY mega casinos making it have the largest draw of gamblers in Colorado. Central City and Cripple Creek do have some big casinos there are only one or two of them in each town. Black Hawk currently dominates the Colorado gaming scene. In the beginning of the casino rush in Colorado (much like the Gold Rush) Black Hawk was the underdog of the three towns that were given legal casinos: Black Hawk, Central City and Cripple Creek. Now there are over four luxury casino hotels one over is over 33 stories tall (Ameristar). In the beginning of legalization there were no hotels. So if you're not that age, please don't visit, sorry!
For the record the legal minimum gambling age in Colorado is 21. Amendment 50 basically boiled down to the following: while the casinos used to have to close at 2:00am, they are now allowed to operate 24 hours a day now! Max bet has been raised to $100, Plus craps and roulette are now available. What started out as small $5 bets has become max $100 bet on Novemwhen Colorado voters approved Amendment 50.
