This is a revisiting of the popular game with a minimalistic interface.

The game is based on numbered tiles that slide on a board in order to create an ordered disposition from 1 to 15, leaving the empty cell in the right-bottom corner.

The included features allow to:
- restart the current game;
- start a new game leaving the current one;
- to have all the instances generated checked to be solvable;
- to count the number of moves to win;
- record the elapsed, effective, time;
- save and restore the last incomplete match;
- restart or resume the old games, visualizing the latest status.
