The challenge here is that the numbers are never in the same position. If the game continues, the number sequence is never like last time.
Currently, 16 levels with 10 stations are available. The higher the level achieved, the more numbers appear on the screen.
If a level is completed, the time for the whole level is saved in "High Score". The game allows to compete with other players.
In the settings, you can store and remove a user name, reset your game or to acticate or disable the game music, effects and game tips.
