BHLS1 is Ben's first set, which consists of 149 Levels. Most of the levels are short concept levels, or simple levels he made before he discovered the community. Not all 149 levels were created by Ben either; some levels were created by his siblings and cousins. A lot of the levels contained invalid tiles however, so the creator edited the set to create BHLS1Lynx, which had 138 levels, and no invalid tiles. The set, however, did not fix all the inequalities, and thus many levels were still impossible in lynx. This set was LPed by the chipster known as Josh Lee, or Flareon350.
