I guess this is a nice game to kill some time with. With the audio on the headset I can imagine myself playing this while in a doctor's waiting room or something like that.
The concept reminds me a bit of Jelle's Marble Runs, a YouTube channel were marble races are shown with real marbles and a very great narrator (Greg Woods). This is a nice virtual marble race. Now I hate playing for real money, but as this is virtual money, I guess it's all cool.
A nice game to give your mind some rest.
