Seidrleik is a Norse mythology-inspired chess variant where fate itself becomes a weapon. Drawing from the ancient magic of Sei r — the power wielded by Odin and Freyja to reshape destiny — players guide pieces that momentarily become conduits for the gods' will. The game transforms the familiar chessboard into a battlefield where mortal strategy and divine intervention intertwine. The flow of each turn is bound by ritual. A player must first move a piece without capture, making it a Seidr-Bearer. This piece then embarks on a journey dictated by an eight-sided die: rolling determines its path across the board, swapping places with any piece it encounters — friend or foe. The Bearer continues moving, roll after roll, until it can go no further, frozen at the board's edge. Only then does steel enter: the player must make a capture with a different piece, striking where the weaving of fate has created an opening. Pawns walk a harsh path in Seidrleik. Those swapped onto the back rank vanish entirely — claimed by the gods. A pawn that bears Seidr remains a pawn throughout its journey, never promoting during the weaving. If it ends its path on the back rank, it too is lost. The only path to glory lies in the Call of Steel: a pawn standing on the seventh rank that captures an opponent's piece on the eighth promotes as in standard chess — a rare moment of mortal triumph amid divine chaos. Victory is brutally simple: capture the opponent's king. There is no check, no checkmate, no special protection for royalty. The king is just another warrior in a golden helm, and the game ends when it falls. With no castling, no en passant, and draws only by mutual agreement, every match continues until blood is spilled — a true saga shaped by the threads the Norns spin. —description from the designer
