I'll be honest and say I wouldn't be watching this if I wasn't a fan of any of them.
But I like the cute Yangmi-Denglun-MingHao trio so I filled my free time with it.

The story is really simple, and there were more games rather than puzzles.
Since they're new players, it's more of a beginners look on solving puzzles on the sisters' team with Da Zhang Wei guiding.
Things I personally really like would probably the setting/costumes and the trio's antics.

So yeah, definitely not a must watch but for more contents of the members you like, go ahead.
