A1: I can't remember what puzzle this is so i'll give you two that I have.
puzzle 1. count the squares and remember what peice is which number in rows. eg. first row=1,2,3
2 row=4,5,6 ect.
with that memorised these are the moves you must make.(move these cirtain block numbers)
3,2,5,4,7,8,5,6 and then 9. tada. its solved!
by the way, this is the fish level with the fish picture.

puzzle 2. you will have a square where the hole has to go in the middle and the colours on the outside. I think!
i don't have or know what to move but, the blue goes at the bottom, green pieces on the left side and red at the top. yellow should be on the right and middle. hope it helps!
