Luck accounts for many reasons. Personally, I suggest that you only open one every day. If a bucket of fish is a bucket of fish every day and a box of meat is a box of meat every day, my friends and I do the same. It feels fast, but the material of that delicious chocolate cake is very troublesome, and most of it is made for an achievement ... As for fishing, I still hope to open some junk items (worth several g), such as hats and buckets.
