I have done each job for 30 minutes and tested which one gave you the MOST Gralats!
Here's the results
Mining- made 182 Gralats not the best, but everyone has different mining levels so it's different for everybody!
Car missions- made 841 Gralats you could get more money, but there was a ton of people trying to get money for gifts and it just depends on how much money you get permission and how fast you can get the mission!
Speedy Pizza- Made a surprising 704 Gralats!
Digging- made 664 Gralats and if you're a tro collector I got 88 of them!
Mail- made 312 Gralats I would only recommend this if you have death revive
In conclusion car missions are the best and if you're a new player do speedy pizza and save for a car which the lowest is 3000 at the car dealership!
