For demonstration purposes. This is the very first app I made (renamed from for trademark reasons back in 2012). This app basically solves a 4x4 grid of letters (or words or no letters) from user input. It returns all possible words from the built-in dictionary that can be constructed from the letters of sequentially adjacent squares, where adjacent squares are those horizontally, vertically, and diagonally neighboring. Clicking a returned word will highlight that word on the grid.更多
