This puzzle consists of five
transparent tetraminoes with thin outlines; they are
shown in the middle of the above grid placed separately,
and at left assembled into a shape.
Tetraminoes can be rotated, flipped over, and overlapped
so that they can make several layers. The object is to
assemble different shapes shown in the vertical line
next to the grid, at left, using all the five contour
tetraminoes every time.
Move tetraminoes dragging them with your mouse, rotate
tetraminoes clicking them. Every time when you move your
mouse over a tetramino it is highlighted. Note, that
some tetromoinoes are asymmetric, and you may need to
flip them over while assembling the shapes of the
Tetramino Contours. To flip any tetramino over just
press the Space bar at your keyboard and hold it while
clicking the respective tetramino.
A small example in the illustration below shows how to
assemble a patterned 3x3 square using a subset of four
contour tetraminoes; every single contour tetramino is
shown in its respective place within the square. |
