So far here is my code  
Pretty Much there is 21 sticks in the beginning the player gets choice between picking 1 or 2 sticks and the AI gets to pick the Sticks when its turn,The one who is forced to pick the last stick loses.  
so far everything good but the AI gets stuck when its the last move not sure why

```auto

The `checkWin()` checks the Win and turns the scene and scenes show win or lose, i think did couple months ago

Yeah Correct but the void created to control the scenes doesn’t work i think or something that controls the scene doesnt work

Use print(scene); in draw() to find out

I have not checked the code since I can’t run the sketch without the images but I can see an error in the `bestChoice` method it should be

```auto
int bestChoice(int s)
{
  int a = s % 3; // 0, 1 or 2
  if(a == 0) { // No best solution so pick one at random
    return int(random(1, 3));
  }
  // Best solution is to make the number chosen add up to 3
  return 3 - a;
}

Also, why does screen switch between 1 and 2 ?

Or why 2 numbers in one line?

I see screen and mode (edited)
