That was my thought too.

> The Word Gem Puzzle is a sliding-tile letter puzzle. The board is a rectangular grid (10×10, 15×15, 20×20, 25×25, or 30×30) filled with letter tiles and one blank space.

Just last week my superior asked to implement that for a customer. /s

Maybe some real, real task would be good? Add sone database, some REST, some random JS framework and let it figure out a full-stack task instead of creating some rectangles?

giving real relatable task like that is memory excercise, not any reasoning excercise. The training dataset have tens of thousands apps like that
