There's one weird trick Blizzard / Netease used to avoid (some of) these laws. A game system that gets classified as gambling usually does the following:

User pays money > User gets premium currency > User presses button > User gets random reward(s)

Here's DI's version:

User pays money > User gets premium currency > User "uses" item before rift > User plays rift > User gets random reward(s)

That extra step means that instead of simply playing a slot machine with real money, you're playing a (very very easy) game segment that gives you (exponentially better) rewards, since you used real money.

Essentially, that distinction makes DI a game of skill, as opposed to a game of chance.
