Loop Sculptor

How to play

1. 1.On the right is a short program that looks like Python. You can change the boxed numbers with − and +.
2. 2.Press Run: the loop places one cube each time around. You’ll see which line is running and the current values of x, y, z.
3. 3.When the placed cubes match the dashed target, the sculpture is done. Cubes outside the target turn red.
4. 4.Every wrong run takes 5 points off your score. Think first, then run.
