Review of Desert Diamond Casino in Why/Ajo

Possibly one of the smallest casinos in the Grand Canyon state, Desert Diamond Why Casino is more of a service station than a casino. Visitors come mainly to fuel up their cars as they pass through on Route 86, or to stop by for a bite to eat and grab a drink.

But once inside there are in fact 40 slot machines offering some of the hottest games which will soon become your favorite titles. And with on-site jackpots, there are some big payouts if you’re one of the lucky winners.

As well as games, there is also the Desert Diamond Casino convenience store where you can grab all the supplies you need to top you up. And if you’re hungry but in a hurry, then the Diamond Deli offers plenty of tasty treats that are quick to eat to fill you up so you can get back on your way.
