Prison – Expert Anti-Slide Packing Puzzle by Pelikan Puzzles

Prison – Anti-Slide Packing Puzzle by Pelikan Puzzles

Prison is a deceptively challenging spatial puzzle designed by Lucie Pauwels and produced by Pelikan Puzzles. At first glance it appears to be a compact packing puzzle, but its true nature reveals a far more subtle and demanding objective centered on movement restriction and internal stability.

The puzzle consists of seven wooden pieces that must be placed inside a rigid 3×3×3 frame. Once the pieces are positioned, the magnetic lid is replaced — and here lies the real challenge. The internal configuration must be precise enough that no piece can slide or escape in any direction once the prison is sealed.

Limited 2×3 openings on each face, combined with single voxel holes in both the floor and ceiling, significantly restrict movement and dramatically increase complexity. While multiple internal assemblies exist, only carefully planned arrangements succeed under the anti-slide constraint.

Specifications:

• Designer: Lucie Pauwels
• Producer: Pelikan Puzzles
• Puzzle Type: Anti-Slide Puzzle, Packing
• Difficulty Level: Expert
• Dimensions: 60 mm × 60 mm × 60 mm (approx. 2.36 in × 2.36 in × 2.36 in)
• Material: Bubinga and Maple

Features:

• Anti-Slide Challenge: Pieces must be arranged so they cannot move or fall out in any direction once sealed.
• Magnetic Lid: Removable top allows full access during placement, then locks the solution in place.
• Restricted Openings: Partially obscured 2×3 gaps on each face severely limit insertion paths.
• Voxel Constraints: Floor and ceiling holes must be filled as part of a valid solution.
• Multiple Valid Assemblies: Over 150 theoretical configurations exist, but only careful planning reveals them.

Why You'll Enjoy It:

Prison rewards thoughtful experimentation and patience. While placing the pieces may initially feel straightforward, ensuring complete internal stability after sealing the lid transforms this into a deeply satisfying expert-level puzzle. The moment when the roof clicks into place — and nothing moves — delivers a uniquely elegant sense of success.

Notes:

• Natural Material Notice: Wood grain and coloration will vary, making each puzzle unique.
• Care: Handle gently to preserve the precision fit and magnetic components.
• Safety: Contains small pieces.
