Rotation Lock Puzzle
The trick to the puzzle is to:
- Get the 2 squares into the center.
- Move a rectangle into the top middle indent.
- Align the rings such that you can move a rectangle into both the left and right indents at the same time.
- End by moving the final rectangle into the center (right).
Figuring out #3 is the hard part, since you need 3 rectangles in order for the outer most ring to rotate. #2 is before #3, because there are only available 2 holes on the outer ring (to move rectangles in at the same time). And they are opposite to each other.
I thought the puzzle was annoying too.
