The challenge here is to place the matchsticks as shown in "Start" above, then move them so that you end with 3 long matchsticks next to each other and 2 short matchsticks next to each other. (As shown in "End" above)
The following rules apply when moving matchsticks:
1. Two matchsticks must be moved at the same time.
2. The two matchsticks must be a long- and a short one.
3. The two matchsticks may not exchange positions when moved.
4. The two matchsticks you pick up to move must be adjacent.
Can you achieve this in 4 steps?
