LO - Can you pack 4 L-shaped pieces inside the frame?
LO is a clever packing puzzle designed by Dr. Volker Latussek.
At first glance, the goal seems simple: fit all four L-shaped pieces inside the frame. But there is a catch — the frame is almost completely closed.
The only way to insert the pieces is through a single L-shaped opening on the back. Inside the frame, two additional pieces are permanently trapped: a flipped L-shaped piece and a circle. They cannot be removed and quickly get in the way as you try to maneuver the four loose pieces into position.
LO offers a satisfying medium level of difficulty. It is designed to provide around 20–30 minutes of solving time — challenging enough to make you think, without turning into an exhausting multi-hour solve.
