On each tile of the grid stands a pillar. The lowest pillar is 1 unit tall, the next 2 units and so forth. That means that in this puzzle there are pillars of 1-, 2-, 3-, and 4-unit heights. Each row and each column has exactly one pillar of each height in it. The higher pillars of course block the smaller ones from view. The numbers and arrows indicate how many pillars are visible from that position (Imagine you are standing in that position, looking in the direction the arrow points. The number next to the arrow, is the number of pillars you will be able to see along that row/column).
