Left or Right

You will see two buttons. One of them is correct but no one knows which one is it.
Choosing the correct buttons in a row gives you 3^n coins (where "n" is a number of selected correct answers in a row)
Earned coins can be used to upgrade the following things:
- chance not to lose the game when choosing the wrong answer,
-chance to get two and three points (intead of 1) after choosing the correct answer.
