  • Arrows snap to valid moves. Freehand arrows can be drawn by dragging the mouse off the board and back while drawing an arrow.
  • Entirely configurable and reconfigurable at any time
  • Styling with CSS only: board and pieces can be changed by simply switching a class

  • Support for 3D pieces and boards

  • Move pieces by click
  • Move pieces by drag & drop
    • Minimum distance before drag
    • Centralisation of the piece under the cursor
    • Piece ghost element
    • Drop off revert or trash
  • Premove by click or drag
  • Drag new pieces onto the board (editor, Crazyhouse)
  • Animation of pieces: moving and fading away
