What is this game?▶
This is standard chess with all normal rules, but displayed as a single 1D strip of 64 squares. Moves are still validated using real 8x8 chess logic, and you can optionally view the synced 8x8 preview board.
Why create this?▶
Other than "why not?", comments on Hacker News by traderj0e and highphive, arguing that chess technically is a 1D game, were a direct inspiration. It might also help with blindfold-style board visualization training... or at least that is the theory. I am around 1500 on LiChess, so please treat this as "enthusiastic field research," not grandmaster-certified science.
What AI/Chess Engine is used?▶
This uses js-chess-engine in the browser for legal move validation, game-state checks (check/checkmate/stalemate), and the optional AI opponent with selectable levels 1-5 from Beginner to Expert.
