I haven't updated to the hotfix version yet, but figured I'd give some report on how gambling is going since that's pretty variable. I'm assuming the "crazy exploit" is something you intentionally have to do.
Value-wise, in v13 I got about 10-18x the value of the 1k chips back, and I'm getting somewhere in the 3-3.5x here, counting apples. It's pretty solid returns. So far I've spun the wheel about 500 times by april. I've got a lot of cool random shit, like an electric lasso, 12 electroflares, 3 blunderbusses with 15 ammo, and some really nice heavy painbringer smg with 5 rounds. But since I can't make any more ammo it's not too crazy.
Also, you get kind of a ridiculous amount of bounty token for jack (and to a much lesser extent zaxx from valuable coins). I'm just at April 7th and I've now got 30mm cannons because I've gotten 1500 tokens already for the confederate gear and cannons. I guess it's not too broken since you can also get a lot from bounty challenges, but this is probably more than intended.
Edit: Oh right, I also got combat shotguns which I could research, and that was pretty huge.
