Objective: Match the YELLOW & ORANGE puzzle footprint by placing chess pieces on the board.

• Ambit: Each piece on the board has its AMBIT, the collection of all squares that the piece can move to. So, by definition, a piece is never its own AMBIT.


Example of a Queen's Ambit.

• Pieces DO NOT block each others ambits. The ambits of pieces do not cancel each other. They coexist.
• Select and place Piece: Click on a piece from the rack to select it. Click on an empty square on the board to place the selected piece.
• Check Progress: Use the "Check" button to view the collective footprint of your placed pieces.
• Lives: You have 3 lives. Placing a piece with an AMBIT outside the puzzle footprint costs a life.
• Placement Rules: Much like in chess, you cannot take back a move.
• Par pieces: Each puzzle has a PAR number of pieces that were used to generate it. Compare this with the number of pieces you use to solve the puzzle (Used Pieces).
• Bonus Stars:
  • <30s gets you 2 bonus stars.
  • >30s and <60s gets you 1 bonus star.
