57DMantis is a vertical casual organizing mobile game that combines book sorting with timed judgment. Players need to tap or drag books from their hand onto shelves of the corresponding category; placing one correctly scores a point, while a single mistake immediately ends the round. As the score rises, the number of books to be sorted gradually increases, and the categories become more detailed from broad to fine. During play, special books such as rush returns, fragile rare editions, signed copies, and return carts also appear, interspersed with challenges like speed sorting and category rotation. Easy to pick up, yet it tests observation and rhythm control.
