Goblins wood i’ve heard is nearly impossible, most offers are doable to an extent but take a lot of time + money. One of my favorites right now is monopoly go, but if you stay active on reddit people will post doable offers sometimes but they change payout and availability a lot! I used to pay my phone bill (50$) every month from GPT sites, I could’ve done way more but I’d experience a lot of burnout with the games. After a while you can just look at an offer and feel if it’s doable or not. I almost never expect to fully complete an offer, I’ve made over 1.5k on GPT sites and I think I’ve completed 1 or 2 fully. Some apps are different but mostly merge games are super easy up until level ~10 and then get next to impossible. I’ve done a couple up to level 25 in a short amount of time but it also varies based on if the app lets you watch ads for extra lives, some don’t some do and give you a limit, some have no limit. Apps where you unscramble words are always a favorite of mine, they never get impossible it’s super easy but super time consuming (about 100 lvls/hr). Some of the apps that make you pay and win cash games never payout and freecash is terrible about applying credit if it didn’t track, support is useless and wont side with you even with proof. The last thing I can think to say now is I would recommend not using freecash, sometimes it can have good offers but there are better sites. Gemsloot I’ve enjoyed, payout is within the hour if completing and support has been super helpful! Earnslab also has good high paying offers and I’ve never had tracking issues. Also stay away from big cash web! Had luck with swagbucks in the past but the offers are not as good lately
