Ruby got me into the game a few months ago and I've been playing ever since. I play it nearly every day once or twice, so I can usually get the daily quests done. Some of those missions are near impossible for me to complete though, like getting a certain high score or amount of tsums, etc. I'm thinking the game checks your own high score and then gives you a mission to get an even higher score. Problem is I just can't reach that score/amount of tsums. I think I'm currently level 26 or something? My highest leveled tsum is a...Gadget Hackwrench I think?? I have no idea what she's called in English so I just Googled her name in Chinese. I use her because I somehow managed to max out her skill level so I get a lot of coins from using her skill in games.
