Think about a number between 0 and 99.
I will try to guess it... Press RETURN when ready.
My guess is 49. Enter '=' if found, '-' if it is too high and '+' if it is too low -
My guess is 24. Enter '=' if found, '-' if it is too high and '+' if it is too low +
My guess is 36. Enter '=' if found, '-' if it is too high and '+' if it is too low +
My guess is 42. Enter '=' if found, '-' if it is too high and '+' if it is too low =
Thank you
