★ How to Play ★
The Board
StarChess is played on a 37-cell hexagonal star (hexagram) board. The board consists of a central hexagon of 19 cells with 6 triangular points extending outward, each adding 3 cells.

37-cell hexagram board
Setup
Each player starts with 10 pieces:
- 1 King, 1 Queen, 1 Rook, 1 Bishop, 1 Knight
- 5 Pawns
White's pieces start on the bottom (rows r=1 and r=2). Black's pieces start on the top (rows r=-1 and r=-2). White moves first.
Piece Movement
Hexagonal chess uses 12 directions: 6 orthogonal (edge-to-edge) and 6 diagonal (vertex-to-vertex).
King
Moves one step in any of the 12 directions (6 orthogonal + 6 diagonal). Must not move into check.
Queen
Slides any distance along 10 directions — all 6 diagonals plus 4 orthogonal directions. Cannot move along the horizontal axis (East/West).
Rook
Slides any distance along the 2 vertical directions (NW and SE). Cannot enter tip cells.
Bishop
Slides any distance along the 6 diagonal directions.
Knight
Jumps to any of 12 fixed positions, ignoring intervening pieces. Similar to a standard chess knight but adapted for hexagons.
Pawn
Moves forward 1 cell (or 2 from starting position). Captures diagonally forward. Cannot enter tip cells except by capture. Promotes upon reaching the opponent's back row.
Special Rules
- No castling — the board is too small for castling.
- No en passant — this rule does not apply in StarChess.
- Pawn promotion — when a pawn reaches the opponent's back row (r ≤ -2 for white, r ≥ 2 for black), it must promote to a Queen, Rook, Bishop, or Knight.
- Check & checkmate — standard chess rules apply. You must escape check. If you cannot, it's checkmate and you lose.
- Stalemate — if a player has no legal moves and is not in check, the game is a draw.
Tips
- The center of the board is extremely valuable — control it early.
- Knights are powerful on hex boards due to their unusual movement pattern.
- The Rook is limited to vertical movement — use it carefully.
- Games are short and tactical — every move counts!
