Chess on Board

The aim of the game is to take pieces from the palette on the left and fit them onto the board to make a chessboard pattern.

How to play the game

Drag/drop pieces from the palette to the board (and vice versa).
Double tap a piece in the palette to place it on the board in the first available position/orientation where the piece can be placed legally (working from the bottom of the board towards the top of the board).
Once a piece is on the board, it can be dragged/rotated directly with the fingers.
A piece on the board can be selected by tapping it. When selected, its border will change colour to magenta.
The currently selected piece can be rotated using two of the toolbar buttons.
The currently selected piece can also be removed from the board and returned to the palette using a toolbar button.
