To host a game you need to forward the port 53893 and share your IP (servers are in the works). Once people join, they can decide at any point to stop syncing with the host and try out their (possible) solution. When they sync back up, their board will be overwritten however (the board from the host will always be used for this; will change in the future).
At this point in time the host can not stop syncing, as he provides all the people who joined with the board (to level the playing field you can open two instances, one just as the server and one to play, a headless version of the host may, or may not come in the future).

An exclusive feature of this app is the scenario system. Scenarios allow you to try out solutions that may or may not work.
Simply start a scenario, if you want to try if a solution works and try entering the solution. If it works, you can keep this board state by pressing "Keep Scenario".
If you find out that solution was wrong you can press "Undo Scenario" to return to state you were at, when starting the scenario.
If you are unsure what that state was you can use the preview buttons above the "Start Scenario" button to look at those boards.
Scenarios in scenarios are also possible ;)
the most recent is always affected by undoing and keeping.

To save your solution you can use the save and load button. These are self explanatory.

The Menus are very experimental (I know it looks like shit (:) and will change (I just haven't found the time yet).
