How to play
Drag a piece with a finger or the mouse. Tap a selected piece again to turn it by 45°, or use the buttons under the board to turn it either way and to flip the parallelogram. Pieces settle onto nearby corners when you let go.
Keyboard: Tab or the left and right arrows choose a piece, Enter picks it up, the arrows move it (Shift for bigger steps), R or E turns it clockwise, Q anticlockwise, F flips the parallelogram, Enter puts it down and Escape puts it back.
Gentle shows the outline of every piece inside the shape, Club shows only the silhouette, Strong adds a hint button that marks a spot still empty. Any arrangement that fills the outline counts, and best times are kept for runs without hints.
