The widest grid yet
Three spaces right.
Two spaces up.
Five moves in all.
What do you notice?
Five moves in the plan.
Five lines in the program.
They match, move for move.
Nova is listening
Say the plan out loud.
Right, right, right, up, up.
Now you are ready.
TRACE THE LONG PATH
Three rights along the bottom, then climb.
Trace the plan with your finger. Then tap the squares from S to the star.
Click S to start, then click each next cell. Path so far: 0 cells
Your finger knows the path.
Now read it as lines.
Then build it yourself.
