Hackenbush

Take turns trimming branches in this classic from combinatorial game theory!

You (Red) and your vicious opponent (Blue) take turns cutting the branches of a bush matching your respective color. Branches not connected to the ground naturally fall and vanish from the game. The last one to make a move wins!

These simple rules make up the classic of combinatorial game theory that is Red-Blue-Hackenbush. The implementation you are looking at lets you play out some levels, against a Computer or with a friend. (Playing with a fiend is also possible)
