This is a rather difficult sliding puzzle to solve! See below screenshots. I have taken a shot every 3 to 5 moves, but someone as clever as you should have no difficulty in solving this puzzle using the below screen-shot hints:
The Curse Walkthrough – Puzzles 70, 71, and 72
Here are the solutions, hints, tips, and tricks
to solve THE CURSE levels 70, 71, and 72!
THE CURSE level 70: Magic Squares #2 – Hard
All directions must add up to 34
I do not know if there are other possibilities, but this one works out:
THE CURSE level 71: Sliding Blocks #7 – Hard
And finally, the Mannequin can slide to freedom!
THE CURSE level 72: UnTangle #3 - Hard
Here you need to be quick and untangle before the time runs out. My strategy was to start with one and then try to make a big circle, following the outer line to the next button. This will get you about a 60% solved solution. Then spread the buttons out in the middle. With a bit of luck you will only need to adjust one or 2 on the outside perimeter to solve with only a few seconds remaining.
