About this app
Three variants of the classic 15 puzzle can be played: 1. Slide the tiles in a random sequence to a selected goal sequence. 2. Select a magic square sequence as a goal, i.e., whose rows, columns and diagonals sum to 34. The empty position contains a phantom 16 tile. 3. Take on a challenge puzzle and from a start sequence, reach the goal sequence in the minimum number of tile moves. Features: * Tile numbers can be changed to Arabic, Eastern-Arabic, Perso-Arabic, Chinese, Hebrew, Indian, Japanese, Korean or Thai numerals. * Tiles in the goal position are outlined in red. * The start tile sequence can be shuffled before play starts. * The color of the even tiles, odd tiles, case and numbers can be changed to any color using a color wheel. * Challenge solutions can be played forward and backward. * Tiles moved to achieve the goal are counted and can be timed. * The Best Overall Score for 15 and 34 puzzles is kept and displayed. * All Settings and scores are persisted between app launches. * Detailed Help on app features within the app and on the support website verusapps.com.
