Next, drag the piece to the square you want to move to. If the move was legal, you'll hear a 'click' and you've made the move.
To see all legal moves for the selected piece, turn 'Highlight Legal Moves' on. You can do this even while dragging a piece by hitting the 'L' key.
If your solution to the puzzle is correct, you'll be rewarded with applause and a green checkmark.
Finally, if Auto-Move is turned on and the game is not over, the engine will make a counter move.
