About Push & Pull ✱✱✱✱
Description:
Push-pull is a cubic box with double panels on one side. Each panel has a wing on the side of the axis. This means when a panel opens the wing sweeps in the 3x3x3 volume of the cube. Five polycubes must be packed so the doors can close. No trivial task, since the lids will quickly obstruct packing, imagination and perseverance are needed.
