They don’t only spawn on full moons in swamps, they just spawn the MOST on full moons, and not at all on new moons. It appears however that the Xbox one edition is broken for slimes. I’ve dug our 4 slime chunks, made 6 iron golem farms in 2 different swamps, and after about a total of 4 hours over the course of weeks, I’ve gotten about 34 slime balls. It’s absolutely ridiculous. What sucks even more is they just updated it the other day and fixed nothing regarding the slimes. They did fix the wither skeleton issue though which gives me hope that this will be addressed soon. I think everyone that’s had this issue is sick and tired of the “light up surrounding caves, they don’t spawn on new moons” answer.
