It's been a long time since the release of Ballance, and its original 12+1 levels cannot satisfy the interest of its gamers, which lead to the appearance of custom maps. Custom maps are made based on the knowledge of properties of objects and the "principles" of map-making in Ballance. This article is aimed at listing all the custom maps that has been created so far. If you want to know how to make a custom ap, please see Mapping page. And about the history of custom maps, please also see the history part of Mapping page. The history of custom maps is roughly recorded there.
Here you will get an overview of the classification of custom maps. Custom maps are currently divided into three types: independent maps, professional speedrun and modified maps, which will be introduced later on separately.
Moreover, due to the large number of custom maps, to quickly locate a map, you may want to use the search bar in the upper right corner.
Independent maps are made indepently or partly derived from available maps by mappers. Some of them are interesting; some are lengthy; and some need carefully thinking. Typically, making an independent level is time and energy-consuming, but that also gives the level high quality and completeness.
Professional speedrunnings are two series of levels made by Burning红云 from Chinese Ballance Forum, which are aimed at competiting skills in playing Ballance and exercising. Compared to independent levels, 虽然这个地图集的地图也是自制的，但是它们都很短小精悍，每张图仅仅只有一个小节。专业竞速非常适合用于针对某一种竞速技术进行训练，也比较适合用于比较玩家之间的技术差异。
Modified levels, or modified maps, are created from existing default levels and custom levels. These include reversed levels, grid-floor levels, 45° levels, and easy levels. Some may be meaningless, just for the desire of the mapper and/or entertainment.
Skill needed for modifying a level is far lower than creating a custom level, thus not only has modifying levels become a preferred way to exercise by new mappers, but also, it gave rise to custom levels. Ballance的自制地图最早起源于jxpxxzj制作的一张反向 Level 1，此后在各个玩家的不停地探索之下，探索出各种技术后，才逐渐从改地图走向制作新地图。
