for #8:
There are 10 different symbols in the puzzle. Each one has a different value between 1 and 10. I used some fuzzy math to come up with the values. I didn't take a screen shot, but I describe each symbol and give it's value.
1 = upside down tree
2 = rightside up tree
3 = target symbol
4 = X
5 = rightside up triangle(tree without a trunk)
6 = boat
7 = The symbol in the center of the puzzle(looks like two cherries)
8 = A triangle on top of a circle
9 = one upright triangle with one upside down triangle inside of it
10 = hourglass
There are 10 small triangles on the board and 4 large ones. Each of the large triangles is made up of 4 of the small triangles(Four within make four). Three of the large triangle are upright and one is upside down(One is inverted). The values of all the symbols in each of large triangles need to add up to the same number(All are equal). All four large triangles need to add up to 23(Thrice and a score).
