I think I've spent close to 5k mora already just gambling on getting the right jadestone. Now I'm not sure if the system is rigged against me or whatnot, but I'm honestly not even sure if there even is a way to correctly guess which jadestone contains the jackpot on the first try. The boss mentions that you can take a closer look, but the only thing you can do is run around the table to look at the stones, which to be honest, look almost exactly the same.
How can you tell which jade stone contains the jackpot in the "Diamond In the Rough" daily commission? Or is it that there are no jackpots?
