That Holly Game

This puzzle game was inspired by a Numberphile video made by Brady Haran and Dr Holly Krieger -'The Dollar Game' . The hexagon based graphs resembles the shape of a Tetrahydrogestrinone particle, hence the name T.H.G. , though it can have other meanings...

The game randomly generates a 3D graph with connected nodes having both positive and negative numbers, the goal of the game is to remove all negative numbers from the graph - you can do sow by either giving or taking from neighbouring nodes.

T.H.G. is free and open sourced, but donations are welcome.

The source code is packed with all the executable versions, but it's also hosted over at GitHub: https://github.com/wezu/dollar_game
