Keep every piece intact
Each piece is made of connected squares. You may move and turn a piece, but not flip it, cut it or put it on top of another. Use every piece once. The outline must have the same number of squares as the pieces together.
Fill a rectangle
These two L-shaped pieces each have three squares. Turn and move them to fill a rectangle with two rows of three. The numbers show where each piece goes. All six squares are covered once.
Try two new outlines
Use the two pieces shown. Both outlines have six squares, so counting alone cannot choose the answer. Imagine fitting one whole piece, then check whether the space left fits the other.
Try it
Which outline can these two pieces fill?
- Outline A.
- Outline B.
Show the answer
Outline B.
B fits both pieces without overlap or gaps. A has the same area, but the arrangement of its squares prevents these two pieces from fitting.
