One by one, we send the requested blocks for the structure by tapping them upwards. As the requested blocks progress, we build meaningful and pleasing structures with the blocks from that complex pile. However, we need to be careful about which blocks to send, as the requested blocks can be found in multiple places within the pile. To meet all the requests, we may need to make selections considering the upcoming moves. To clearly see which blocks will go, you can tap and hold to inspect the selected objects.
