# Reverse puzzling. What game is this?

I saw my friend working on making a computer game version of an old game (not traditionally a computer game) and his notepad has these strange series of numbers. What game is he working on?

(1,2,3)
(4,5,6)
(7,8,9)
(10,11,12)
(13,14,15)
(16,17,18)
(19,20,21)
(22,23,24)
(1,10,22)
(4,11,19)
(7,12,16)
(9,13,18)
(2,5,8)
(17,20,23)
(6,14,21)
(3,15,24)


And he says that is the complete set of sets (whatever that means!)

Any ideas?

This refers to

Nine Men's Morris.

which uses this board

    1-----------2-----------3
|           |           |
|   4-------5-------6   |
|   |       |       |   |
|   |   7---8---9   |   |
|   |   |       |   |   |
10--11--12      13--14--15
|   |   |       |   |   |
|   |   16--17--18  |   |
|   |       |       |   |
|   19------20------21  |
|           |           |
22----------23----------24 

The listed sets are

all the possible ways to get get three of your pieces in a row horizontally or vertically, which is a goal of the game.
