Solution for stack of boxes.....
Move the box at the bottom left to the top right, as far over as it can go. It should line up with the blue gem and they all drop down
Niagara Falls level
Pillar of Strength
Drop the purple and green piece that is at the top and center onto the green hearts to the left.
Switch the red and purple gems at the two bottom corners and wait.
Carefully slide the green and purple piece over to the right. Puzzle solved.

Spin the bottom row. Spin the very top row. Then spin the middle section (the one that looks like a frown) with the red and purple. The first two moves will not clear any gems, but the third one will clear them all.
If you still remember it I'd love the answer! I've been stuck on that stupid puzzle for three days now!
For the Pirate puzzle, move the single blue gem which is on the 3rd row down, put it on top of the L shape green gems (3rd row from the bottom, 2places in from the right).
