Chessboard Tours

Two chessboard puzzles. In the Queen's Tour the queen moves along a row, a column or a diagonal any number of squares, may cross squares already covered, and must cover all 64 squares; it can be done in 14 moves, ending where she began. In the Bishop's Tour the bishop starts on a white square, moves only diagonally, may not land on a square already covered, and must visit all 32 white squares; it can be done in 17 moves. Every square the piece leaves or crosses is marked with a gem, and the queen's starting square is ringed so you can find your way home. Your move count is shown against the target. Stuck? Ask the computer to solve the tour, and watch the piece glide through it square by square.

Controls: Use either joystick. The stick moves the cursor; the left button places the piece, then moves it to the cursor's square. The right button opens the menu (SOLVE, END, BACK): up and down choose and a button picks.
