# G4G12 Exchange Gift

Ziggy

Ziggy is a small packing puzzle that I designed. I used it as the exchange
gift for the Gathering for Gardner 12 conference in 2016.

The puzzle is based on the fact that 1+2+3+4+5+6+7+8 = 6^{2}. There
are 8 zig-zag polyomino pieces, ranging in size from 1 to 8 squares. The basic aim
is to create a 6 by 6 square. The pieces are shown here:

There are two very closely related solutions to the square, but there are
also several other challenges you may like to try. Here is a selection of 18
shapes that can be made from the 8 pieces:

1.

2.

3.

4.

5.

6.

7.

8.

9.

10.

11.

12.

14.

15.

16.

17.

18.

## Solutions

Here are solutions to each of the challenges. Both solutions to the 6 by 6
square are given, but for the other challenges only one solution is shown even
though there may be more.
