Wood Stacks

It is known that beavers are masters at building dams, but recently there is less and less wood and the animals have to save. In Wood Stacks, you help the beavers make the most of the limited number of wooden blocks of different shapes. The task is to fill the holes with blocks, and the dotted border above the dam should turn green. If a block extends beyond the border, it turns red, which is wrong. Rearrange the blocks until you achieve the desired result and complete the level in Wood Stacks.
