Giant Book Reversi

You play white against the computer's black on an eight by eight board that starts with two pieces each in the centre. Put a piece so that one or more lines of computer pieces lie between it and another of yours, across, down or on the diagonals, and they all turn over. The game ends when the board is full or neither side can move, and the most pieces wins.

On the CLASSIC level the computer plays as the book's program does: for each free square it counts the pieces it would turn, doubles that on the edges, halves it on the squares next to the edges and halves it again beside the corners, and plays the best square, choosing at random between equal ones three times out of ten. A new MASTER level also looks at your best answer to each of its moves and avoids giving it. Small dots show where you can play, a turn you cannot play is passed for you (the book asked you to type 0), and the pieces turn over in steps. New music (Queen's Gambit Rag) is added.

Controls: either joystick. The stick moves the cursor; a side button plays the square. The keypad is not used.
