This has happened the past couple days (I'm a noob) I have no trouble (well, when I don't suck at the games) getting gold, and then, out of nowhere, I'll get a small amount, and then nothing (keep in mind, this is when I do well enough to get some).
I assume it's because there's some kind of limit (which sucks because I have a hard enough time getting gold without one ). If so, what kind, and how much? A certain amount of gold? A certain amount of times you played a game? If not, then what?

Please help. Thanks!

There's a 250 daily limit on the games. Once you hit 250, you don't earn anymore for the day.

There is a max of 250gold per day per account that you can earn :3 (So if you had a mule you could own a total of 500g from both your main and mule accounts).

Within each game there is a small limit as well. Attack of the Fangirls and Sardine Smash net you 100g (if you score that high enough). Every other game nets you 50g (if you score that high enough).

So it doesn't matter how many times you play. Just the total.
