If you are organized and want to keep track of which buildings are at which particular level, you can purchase 3 different types of ink: Blue, Red, and Yellow. Then to keep track of level 1 buildings, you could, say, keep them at their natural color. For level 2 buildings, you could label them with Yellow ink, level 3 buildings with Red ink, and for when new building levels are released, you could start using Blue ink for level 4s, and then hope that TNT will also release a more varied set of ink colors for us to use. Alternatively, you could come up with your own system, for example: Natural colors for level 1-2s, Yellow ink for level 3-4s, Red ink for level 5-7s, Blue ink for level 8-10s – whatever strategy you feel most comfortable with. And again, this is totally optional but it’s great for keeping everything organized in case who knows how TNT might plan to change the game later on and this might prove to become a useful asset for you.
