This works because after completing two sides of the square, the next side is one shorter. 3. Challenge: "Maze Runner" (The Holy Grail of Karel) Problem: Karel is dropped into a random maze. Use the "right-hand rule" to escape. Karel must find the ball (the exit) at the bottom right. Run it

This requires Super Karel ( turnRight ). For standard Karel, you replace turnRight() with turnLeft(); turnLeft(); turnLeft(); . 4. Challenge: "Repair the Row" (Fixing potholes) Problem: Karel must travel down a row. Every 2nd, 3rd, or 4th cell is a "pothole" (a missing ball). Karel must put a ball in every pothole and end at the far wall. That is how you reach the top

It doesn't matter if the potholes are random or specific. It solves 100% of "row repair" problems. 5. Challenge: "Checkerboard" (The hardest basic Karel) Problem: Cover the entire world (any size) with balls in a checkerboard pattern. A ball on (1,1), no ball on (2,1), ball on (1,2), etc.
