your problem is that you have defined your variables as random numbers and the start of your program, and then not called randint again to change them. To fix this you need to call randint for your variables inside your main loop so they will have different values each time the loop executes

Ok. You have variable boulder1Y. Then you make a random number and assign it to variable number4. Lets say that the random number outputed 150. number4 is equal to 150.  Then you makeboulder1Y equal to number4- so now boudler1Y is equal to 150.

Then you begin your loop. The first time through the loop, the boulder is drawn at boulder1Y- which is 150. The second time it is draw and boulder1Y, which again is 150 because you have never changed the value of it.

To solve your problem, you have assign a random number to boulder1Y every time it reaches the end of the screen. What you could do is change this code:

    
if boulder1X + boulderWidth
