Actually it’s part of the game experience to find out how the controls work.
But to give some assistance i implement the autoplay mode. Hm, however it seams it's still not very clear how it works.
Here is some hint:
Every time the colour of the shape changes the roulette must be touched to synchronize the colour filed,
then you can press the button of the recognized shape. If you touch the roulette while the colors are synchronized,
the roulette gets over synchronized and that will cause a fail. (Hope that helps)
One more hint you find your name in the game if you touch “2015 robin”, this will open the credits screen.
Thanks for your work on the engine.
