It's hard to get blue stones..😢

Today, I got even fewer blue stones than yesterday.. only 390..😭😭 Ugh, I can keep grinding for red stones, but there's no such thing for blue stones, which is frustrating..😢 I keep thinking about when I'll ever collect 5000 to exchange them..😅 Getting blue stones requires not just effort but also luck.. I wonder if I'll barely make it?..🥺✨ Please help me exchange them for draw tickets!😂 I'll have to run hard again after work to get more red stones.. (Issue with today's blue stone quota reached..😢) I also finished all the missions yesterday, so this is all I have left to do.. It's a shame.. How many stones have you all collected?😊 Actually, I've saved about 100 purple stones.. If you include the ones I've exchanged, maybe around 140?🤔
