GAMMONLAB Board (picture below) has 2 modes:
- Play Mode
This is a default mode that allows only legal moves. You can move by dragging checkers to any pip highlited in bright green (see picture below). To move back (undo the move), you can drag the checker that just moved back to a pip highlited with yellow. Instead of moving the checkers by yourself, you can move them by pressing 'Best Move' button & GAMMONLAB will make the best move for you.
- Setup Mode
This mode allows all checkers to be moved to any pip. To use this mode, select Setup Tab control on the right hand side.
