Our Direction enum can then be enhanced with two helper methods to determine what are the valid moves (I'm borrowing Streams from Java 8, but I don't think it's that hard to replace it with loops for a < Java 8 implementation): The trick we employ in isValidMove assumes that the Border enums have the same names as our Direction enums to simplify the logic (returning false when the name()s match), alternatively, you can replace it with a more full-blown switch logic. Swift - Seeding arc4random_uniform? Up - Not available, since the last move was down (reversing itself) Right - Not available, since there is a wall directly to the right Down - Available Left - Available From here we can see that should it move down, then the same availability will occur.
