Abstract
In some embodiments, a wall block system has at least one block, multiples of the at least one block being suitable for use in constructing a wall from multiple courses of the blocks stacked one upon the other. For example, the wall block system can comprise at least one block having opposed first and second faces, the area of the first face being greater than the area of the second face, wherein the first face or second face can serve as an exposed face on one side of the wall, and each block having an upper surface and lower formed with a single central slot to receive a three-way block-connecting element thereby allowing vertically adjacent blocks in a wall to be interconnected in three different positions to establish a neutral batter, negative batter or a positive batter between blocks in adjacent courses.
