Hint 2 of 2
Any path that lands on a blue water square is not allowed, so cross it out; the good path stays on dry land all the way to the koala.
Show solution
Approach: trace each arrow path and reject any that hits water
- Start at the kangaroo in the corner and follow each option's arrows, moving one square per arrow.
- As soon as a path would land on a blue water square (or leave the grid), cross that option out.
- Only path C stays on dry squares the whole way and reaches the koala, so the answer is C.
