Add hinting feature to Fifteen (press 'h' for a hint).
This is really an incremental solver. It alternates between solving rows and solving columns. Each row and column is solved one piece at a time. Except for some temporary trickery with the last two pieces in a row or column, once a piece is solved it is never moved again. (On non-square grids it first solves some rows or some columns until the unsolved part is a square, then starts alternating.)

Pressing \q{h} will make a suggested move. Pressing \q{h} enough

times will solve the game, but it may scramble your progress while

doing so.
