I can't earn PlayO points because of Merge Dragons

After finishing all the quests early in Merge Dragons... I've been playing this game mainly because it's fun even without quests. I used to collect PlayO points by doing quests in one or two other games for a short while... Now it's been ages since I've even looked at other games ㅎㄷㄷ As time-quest games appear based on age and gender, maybe because I'm older, the recommended games are things like card games or 'matgo' (a Korean card game). I downloaded one out of curiosity for the points, but it was so boring that I only played it once or twice. The reason I use PlayO is because I was hoping to exchange the points for gift certificates 🤣 I've played many other merge-type games too, but their patterns are so predictable that I don't even want to start them 😅 I'm just stuck with Merge Dragons 🤣 If they let me keep buying gem boosts with hearts, I could pour everything into Merge Dragons, but I can only buy one of each type per month 😥
