Where is the gambler?

Diablo 2 had a gambler where you could purchase items before knowing what magical properties they'll have.

I'm about halfway through Diablo 3 and have yet to stumble upon a gambler. Has anyone found him? If so, where is he?

Solution 1:

In Diablo 3: Reaper of Souls you can find the Gamble merchant, Kadala, in Adventuring mode. To gamble, you spend Blood Shards that are earned through completing Bounties and within Nephalim Rifts (The Rift Boss seems to drop large chunks).

Solution 2:

There is no gambler. You can get something similar - gear with random stats by paying gold - by using the Blacksmith Artisan, but that's the closest there is in Diablo 3.
