Hey,
there is no Need to put +1 in the Random.Range!
Because we put the Method OnPressHigher() to min = guess +1 the logic goes that if the guess is 999 and we hit higher the min will go to 1000 and the next guess will therefore be 1000.
So no Need to put Random.Range(min, max+1).
Try it.
And in the case I’m wrong, please tell me.
