You’ve purchased both your own personal chess trainer
and a partner who is always ready for a game! The chess
board is made up of eight vertical rows called files, and
eight horizontal rows called ranks. Each file (left to right)
is designated by a letter (A to H ), and consists of eight
squares alternately colored green and white. Each rank
(bottom to top) is designated by a number (1 to 8), and
consists of eight squares alternately colored green and
white. The green squares are referred to as “black”
throughout the rest of this user’s guide.
When it is your turn, press SETUP+/HINT to view
suggested moves. HinT appears with a recommended
move. To take it, press OPTIONS/MOVE. To make another
move, press NEXT PIECE or LAST PIECE.
Piece
Move your piece into an occupied square to capture the piece located there. Remove the
captured piece from the board.
Castling protects the king from a potential check or checkmate situation by hiding it behind a
fortified position or moving it away from danger of attack. You can castle if:
• The king has not moved from his original position.
• The rook that you want to move by castling has not moved from its original position.
• No opponent’s piece attacked the king’s original square, or the squares which the king
must cross, or the one which the king is to occupy.
• The squares between the king and the rook are not occupied.
• You cannot “castle” after undoing a rook or king move.
• If a rook is on the same side of the board as the king’s square, it is called a king’s side
castle. If the rook is on the same side of the board as the queen’s square, it is called a
queen’s side castle.
• In castling, the king moves two squares in the direction of either rook. The rook closest to
the king after the king moves can now move to the square right next to and on the other
side of the king. Castling counts as one move.
playing basic chess
E-Chess starts a new game with you playing the white pieces and your opponent playing the black pieces. To start a
new game and erase games stored in memory, press 2nd, then NEW GAME/HELP. 01CHESS appears.
Playing against E-Chess is like playing with a human opponent. You make your move, and E-Chess responds with its
move. Making a move involves a “from” square and a “to” square. The “from” square is the current location of the
piece you plan to move; the “to” square is where you are moving the piece.
1. When it is your turn, repeatedly press NEXT PIECE or LAST PIECE to select the piece you want move. The piece alternately
flashes on its “from” square and one of its legal destinations.
2. If the move that appears is not the one you want, repeatedly press NEXT MOVE or LAST MOVE to select other legal moves
for the piece.
3. Press OPTIONS/MOVE to make your move. If you decide you want to take back your move, you must wait until E-Chess
makes it’s next move. Then, press /UNDO twice to take back E-Chess’s and your previous move.
• You cannot enter a command before E-Chess makes its move.
• If you do not want to wait for E-Chess to calculate a move, press OPTIONS/MOVE to force the move.

checkers rules
Each player gets 12 checkers and places his pieces on
the dark squares in the first three rows in front of him.
Players take turns moving, and black moves first. The
first player normally moves from the “bottom” of the
board. The goal of checkers is to leave your opponent
with no legal move, either by taking all of his pieces or
by blocking his pieces. Move your pieces diagonally
forward, staying on the dark squares. A piece is
captured by jumping over it to an empty square. A
piece cannot jump over its own pieces. Captures are
obligatory. When a piece reaches the other side of the
board, it is promoted to king. Unless you instruct the
game otherwise, you have the black pieces, and black
always moves first.  indicates it’s your move. A move
consists of two parts, choosing a “from” square and a
“to” square.
1. Press NEXT PIECE or LAST PIECE to choose a piece to move.
captures
Press /UNDO to take back your last move.
Capturing is obligatory in the game of checkers,
although if you have a choice of captures, you choose
the one to play. When it’s your turn and you have a
jump to make, JP appears. E-Checkers knows the rules
and will stick to them! Make your capture, and proceed.
multiple captures
If there are multiple jumps possible, the “from” and “to”
squares flash. All intermediate squares the piece landed
on while jumping have a king’s cross on them. Some
multiple jumps have two paths to the same square.
Press NEXT MOVE to view both possible jumps.
turn pieces into kings
At the start of the game, all pieces are referred to as
“piece”. When a piece reaches the far side of the board,
it is crowned “king”. A king is much more powerful
because a king can move backward and forward.
E-Checkers automatically crowns your piece a king. A
piece that promotes to a king by making a jump cannot
continue jumping as a king. You must wait your turn.
care

immediately. Use and store the game only in room
