I recently started playing chess and was doing some puzzles online. It says that this move is checkmate but I don't see why white can't move to b1. Can someone please explain?

    It means that mate will happen not that it has already occured. See Phishmasters full answer below.

  • Maybe this puzzle shows the tower in the wrong color (that is, it should have been a black tower instead of a white one).

No, the white king can still move to b1.

That said, Kb1 Qb4+; any Qb2 is mate.
