Replaying Moves

Probe lets you move back and forth through the move sequence, to explore game variations.

Undo

Reverses the last pair of moves in the game: Probe's and yours. You can undo moves all the way back to the beginning of the game, even if you save the game and later resume it.

Redo

Replays the next pair of moves you previously undid, provided you didn't undo several moves and then make a new one.

Start Over

Begins a new game from the original position.
