Long Chess

Two boards joined into one 8×16 field

Push two boards end to end and play on a board twice as deep. The extra distance completely changes how pawns, rooks, and endgames behave.

How it plays

  • 1

    The two boards form one continuous 8×16 field.

  • 2

    White starts on the near board, Black on the far edge of the second.

  • 3

    Move hints ripple across the seam onto the other board.

  • 4

    Pawns have a much longer march, so promotion becomes a real project.

What the lights do

Legal-move hints continue across both boards, so a rook's range lights up sixteen squares deep.

What you need

  • Two boards
