Note: moves are commutative in this game, so clicking once "+" and once "–" on the same node at different points of the game cancel out and make 0 moves.
Graph validation:
To move nodes just drag & drop; To edit a number in a node use buttons that appear when hovering over it.
Shortcuts: 1, 2, 3, 4.
Save/Load graph
This string represents the graph with the current values (make sure to hit "restart" beforehand if you've played some moves, but want the original numbers)
You can copy the string and send it to a friend. Or you can paste a string that a friend sent you here and hit "Load from string".
