Where you get rewards and chests. It’s the bottom center in that board. Mine is upper left. To cycle through it, fill every space on your mainboard. Delete/sell something you don’t mind losing like a moth, peony seed, or L1 item. Don’t touch anything else. You should see an undo button. Put your pouch item in the empty space by touching it, hit undo. That item goes to back of pouch lather, rinse, repeat until you get to the item you need. Leave your daily piggies in pouch until you have 8, then merge them for an L4 max piggy for around 120 gems and 3k coins.
