This puzzle is similar to but different from number 125.

Place 6 sticks as shown in Figure 1. The challenge is to end as shown in Figure 2 with adjacent matchsticks pointing in opposite directions.

Start by picking up 2 adjacent sticks and place them next to the others (to the left or right of the layout) and continue doing this until you get to the layout as shown in Figure 2. The following rules apply when moving the 2 sticks:

1. The 2 sticks must be moved simultaneously.
2. The 2 sticks you move must be adjacent.
3. The 2 sticks you move may not be turned around vertically.
4. The 2 sticks you move may not change positions.
