'1D-Chess' is a one-dimensional chess game played on a board with just one row.

1D-Chess is a variation of chess played on an 8x8 board, but using a smaller board with only 8 squares in a row and a limited number of pieces. 1D-Chess is a mini-game introduced in a science magazine in 1980 and can be played at the following website.

The 1D-Chess game playable on the above website uses three types of pieces: King, Knight, and Rook. The Rook moves like a rook in shogi, and can move any number of squares forward or backward.

The knight's movement is similar to that of the knight in shogi, but in 1D-Chess, it can jump two spaces forward and backward. The king's movement is the same, one space forward and one space backward.

The rules are simple: 'You win if you checkmate your opponent's king.' However, if the same move is repeated (resulting in a draw), if it becomes impossible to check, or if both players end up with only their kings, it's a draw.

The player goes first, using white pieces. I started by moving my knight forward, and my opponent's knight also moved forward.

So, I use the white knight to capture the opponent's rook. At the same time, I've managed to put the opponent's king in check.

Then, the black king moves forward and escapes check. If you're curious whether checkmate is possible, try playing the game yourself.

Even if the game ends in a draw, you can start playing again from the beginning by clicking 'Restart Game'.

Additionally, the social news site Hacker News featured ' Mind Chess ,' a game where players endlessly call each other 'check' and wait for the right moment to say 'checkmate' first, as well as ' PAKU PAKU, ' a Pac-Man game played using only one line of text.
