Twist Them In
Twist Them In is a clever packing puzzle with a mechanical twist. The container consists of three parts — a base, a rotating lid, and a removable hatch that serves as the entry point. Because the lid rotates eccentrically, the hatch only opens when the lid is turned exactly 90°, 180°, or 270°.
Your challenge is to fit four pentacube pieces into the container and close it completely. Sounds simple — but the restricted opening and rotation mechanism make this far trickier than it first appears. Solving it requires spatial imagination and mechanical insight, rewarding you with a satisfying “click” once everything is in place.
