You can move the pieces with the mouse by drag and drop. To rotate you have to press these keys: R (for the red piece), Y (yellow), G (green), D (dark blue), L (light blue), O (orange) and P (pink). For some shapes you have to flip the pink piece with the F key. To reset press the space key. With the up and down arrow keys you can change the size of the pieces.
You can try to make some shapes, e.g. a house, a ship or a rectangle. The shape must contain all seven pieces. And the pieces may not overlap.
