Qe4+ is illegal.
Nd5 is illegal.

None of those moves are legal--I think you have your board rotated. Also the pawn is moving downwards and denies the knight all the squares it needs.
I'm kind of baffled by this one. Yes, it pins the rook, but can you capitalize on that?

the board posted is flipped, i have the coordinates correct for the puzle
the puzzle in the link and the puzzle I posted have different coordinates. Idk how to change the board's coordinates so I just removed them on the one I posted

Engine thinks that pinning the rook is a great move although I have no clue why. I would assume that the reason Is black getting an extra move but I'm not sure why that is great.

Yes board is rotated. Theoretically drawn position until king goes to a8. Pinning the rook allows black's Knight to develop, and if the King tries to free itself from the a8 square to allow the pawn to promote then there are lines later like mate in 12 for black, which any 600 rated player should be able to calculate (joking of course).
The rating is frankly bizarre given the complexity of the continuation......

Found the actual game for you. Black didn't find the engine continuation either (forward to move 73 for Qe4+) but still won the game.
Okay, so here is the full explanation of the puzzle:
1. This is a 600-rated puzzle.
2. Therefore, the solution is the most obvious check. It has to be.
3. The most obvious check is Qe4+, amitite?
4. Solved!

Thanks. He ended up going to Qd6 which was my guess when solving the puzzle (Move 75). Just different order of moves

The position was extremely complicated. There was no way that I would see all of that lol

Don't chess.com puzzles work by top engine move? If so then isn't unlikely that the only check would work.

as i mentioned earlier the rating is likely because the first and only move is obvious (1.Qe4+) as there really isnt any other clear options.
edit: puzzle rating is found by using essentially the elo system for player vs player, but with puzzle vs player. so if it is a simple one move check beginners will see it without knowing the extra complications thus giving it a low elo.

The logic goes in the opposite direction. Puzzles that have an obvious check as the solution will have a low rating - just like here. This puzzle is complex, but it does not matter. Low rated players will calculate nothing, they just play the most obvious move without thinking... and they "solve" it.

I swear that chess.com puzzles solutions were top engine move... not the obvious move. I may not be correct tho but I'm like 90% sure

they are the top engine move, this happens to be the case where it is an obvious move too

I take everyone's point here. I don't think it's helpful at the 600 level to have a "one right move" where the continuation can't be easily understood. People need to be able to learn, not be told "you're 600, the reason is 'just because' " - that's lazy parenting 
Maybe restrict the puzzles at that level to the shorter continuations only to remain instructive? The reason for the obvious check is that any other reasonable move is a draw, which I don't think is obvious at the 600 level, so the value of the puzzle as a learning tool is questionable. Anyway, fun discussion, thanks all

yeah chess.com puzzles are rather lackluster and are of very low quality. I think lichess puzzles are a much better option and provide better learning experiences as well as more patterns to learn (chess.com has a lot of mating patterns especailly at lower level especially ones involving backrank) while lichess has a more balanced and reasonable amount of puzzles that have unique patterns to learn. also as a bonus lichess is free lol.
Encountered it while doing puzzle rush, specifically Puzzle 9. I was initially surprised that I couldn't solve a 600 rated puzzle. Spent a while calculating what the move was, I ended up getting a lot of draws but it's 12 points of material vs 10 points of material so I discounted them (should be a win for black). Solution was apparently just a check. Afterwards, I did an analysis but I don't understand why checking with the queen is the solution (It just paralyzes the rook...). Anyone with an explanation?

Ngl, this 600 puzzle is harder than the 2400 puzzles I encounter.
